Cangshanaltica ogatai Takemoto & Suenaga, 2021 Cangshanaltica ogatai Takemoto & Suenaga, 2021: 146 Type locality: Japan, Okinawa, Iriomote isl. Type series: Holotype —SEHU; paratypes: HSPC, TTPC. Remarks. Cangshanaltica ogatai is the only species described, so far, which has an elytral pattern with multiple spots. This coloration is uncommon among Cangshanaltica species distributed in continental Asia. Species with a similar color pattern are distributed also in Taiwan, however, we hesitate to either assign them to C. ogatai or describe them as a new species (see comments below).

(2) sifting of leaf litter and leaf accumulations along stony stream in evergreen lowland subtropical forest [sifting sample 13]; (3) VOUCHER SPECIMEN DNA collection No. AFD-125 Albert F. Damaška coll. Differential diagnosis. The species can be distinguished from all other known Cangshanaltica species by its coloration—elytra ochraceous with one darkened spot in the center of each elytron. DNA sequences. 18S: MZ312403.1; 16S: MZ312387.1; Cox1: MZ303694.1, MZ220536.1 (barcode). All sequences were published by Damaška et al., 2021. Description. Habitus. Body round, convex, 2 mm long, 1.7 mm wide, 0.9 mm high. Dorsal and ventral surfaces ochrebrown, each elytron with a darkened spot in the middle. Head. Nearly hypognathous, triangular. Labrum and clypeus blackish brown, vertex brown.Frontal ridge absent; frons shiny, impunctate, with bunches of setae below antennae. Frontal calli nearly absent. Suprafrontal sulcus shallow, orbital and supraorbital sulci developed. Eyes round. Antennae reaching basal 1/3 of elytra. Antennomeres I–VI and XI light brown, antennomeres V–X darkened. Antennomeres I and II bulbose, wide; antennomeres VII–XI elongate, as long or longer as antennomeres III and IV combined.Antennomere VII bearing a slight distal protrusion. Thorax. Pronotum brownish ochraceous, wide, convex, impunctate. Anterior margins of pronotum lobate, projecting, forming distinct “flap-like” structures towards head; posterior pronotal edges dull. Anterolateral pronotal setiferous pore placed in the middle of lateral pronotal margin. Elytra convex, brownish ochraceous with a darkened spot in the central part of each elytron, irregularly punctured. Epipleura distinctly widened in basal part. Anterior metaventral process completely covering the mesoventrite between mesocoxae, as a sharply pentagonal, deeply excavated “horseshoe-like” structure. Legs brownish ochraceous. Metatibiae slightly curved, apical metatibial spine short. Metatarsomere I slightly elongated. Abdomen. Abdominal ventrite I longer than ventrite II, but not as long as ventrites II and III combined.Anterior process of abdominal ventrite I reaching space between metacoxae, bulbose, forming a sharp, ventrally projecting elevated ridge. Genitalia. Median lobe of aedeagus long but wide, parallel-sided in dorsal view, slightly curved in lateral view. Apex dull, slightly widening posteriorly. Female unknown. Remarks. The only known specimen is apparently not fully sclerotized—the coloration of a mature adult is probably somewhat darker. Despite that, we are describing the species, as all morphological characters are welldeveloped, and available DNA markers clearly indicate its isolated phylogenetic position among other studied Cangshanaltica species (Damaška et al. 2021). Etymology. The species name is derived from Guanxi, the name of the Chinese province where the holotype was collected.

Ivalia sichuana Medvedev, 2016 Comments. We were unable to study the type specimen from Erland Shan Pass, Sichuan deposited in Medvedev’s private collection. Instead, we examined a photograph made by A. Moseyko of the box containing the type series of Ivalia sichuana. Based on this photograph, it seems likely that I. sichuana belongs to Cangshanaltica., Published as part of Damaška, Albert František, Ruan, Yongying & Fikáček, Martin, 2022, The genus Cangshanaltica (Coleoptera: Chrysomelidae: Alticinae): overview, new species, and notes on species complexes, pp. 49-64 in Zootaxa 5219 (1) on page 61, DOI: 10.11646/zootaxa.5219.1.2, http://zenodo.org/record/7408144, {"references":["Medvedev, L.

Cangshanaltica castanea had been described in Taizonia by Gruev (1985), a genus subsequently synonymized with Ivalia by Duckett et al. (2006). Due to homonymy with Ivalia castanea (Samuelson, 1966), a new name Ivalia gruevi was proposed for the species by Nadein (2013). Our placement of Gruev’s species in Cangshanaltica makes Nadein’s replacement name redundant (ICZN Art 59.4). We move the species to Cangshanaltica based on the following characters: (1) antennomere VII bearing a slight distal protrusion; (2) metaventrite bearing an anterior, horseshoe-like process reaching mesocoxae and covering the mesoventrite; (3) anterolateral pronotal setiferous pore placed in the middle of the pronotal margin; and (4) round, ovate, and convex body shape. Cangshanaltica castanea is similar to other Chinese Cangshanaltica species distributed in lowlands— C. sprynari, and C. fuanensis. The species can be distinguished using the key below. Type locality identity and distribution. The type locality “ China: Da-laen-saen” named by Walker has been discussed by authors who have revised J. Walker’s Chinese material (Schawaller & Aston 2017; Smetana 2009). According to their findings, the most likely type locality of C. castanea is China, Zhejiang prov., Ningbo pref., Dalei Shan (kDZ山), cca 29.5928 N, 121.2930 E. The second Walker locality in the BMNH material is “Nyew-tew I.” This locality refers most likely to the Nantian Dao Island (Éffl岛) in Zhejiang province, named “Nyew-tew Island” in 19th century Western maps, likely after the island’s peak Niutou Shan (牛Ë山). The second type locality should therefore be: China, Zhejiang prov., Ningbo pref., Nantian Dao (Éffl岛); cca 29.1361 N, 121.9388 E. Additional specimens assigned to the species complex of C. castanea were collected recently in Lu’aocun (炉岙村) in the Lishui prefecture, and in Hangzhou, both in Zhejiang province, China. Species identity and variability. Cangshanaltica castanea was described based on a type series collected by J. J. Walker. Besides the type series, we examined additional Walker material from the type locality (Da Laen Saen) and its surroundings (Nyew-tew I.). We also collected fresh DNA-grade specimens in southern Zhejiang —they strongly resemble several specimens from the C. castanea type series. All the specimens have similar morphology of external characters and female genitalia, however, the morphology of median lobe of aedeagus is quite variable among all specimens, even within the type material (fig. 3 G–H). Specimens also differ in elytral punctuation (in the holotype and most of Walker’s specimens, elytra have very feeble punctures, in several of Walker’s specimens and all the fresh specimens from Lishui, punctures are shallow but distinctly visible, forming a pitted elytral relief, similar to the surface of a golf ball), and size (males are up to 1.9 mm long). A similar species in external morphology is C. fuanensis Ruan, Konstantinov & Damaška, 2022, which differs in having a more slender median lobe of aedeagus, but is strongly divergent from the Lishui specimens based on DNA phylogenetic analyses (Damaška et al. 2021). This strong difference in both mitochondrial and nuclear DNA markers among the two morphologically similar species suggests that the C. castanea species complex can consist of more species which are similar in morphology but phylogenetically isolated from each other. Due to the lack of any DNA-grade material from the two historical collecting sites in Zhejiang, we decided not to treat any of the specimens with different genitalia morphology as distinct species. However, the variability of median lobe of aedeagus in C. castanea in our understanding is apparently larger than in other Cangshanaltica species. The species definition of C. castanea may therefore represent a species complex. A careful analysis of DNA and morphology based on fresh material from more localities in Zhejiang and around (including Walker’s sites) is the only way to yield enough information to resolve the C. castanea species complex.

Tung Comments. In Taiwan, Cangshanaltica is a common genus, with at least two species well-delimited based on molecular analysis (Damaška et al. 2021). All examined species from Taiwan have spotted elytra and are generally similar to the Japanese C. ogatai Takemoto & Suenaga, 2021 in all external characters, except for the coloration: Taiwanese specimens have 4 elytral spots, C. ogatai has 6 elytral spots. The dorsal body coloration among different Taiwanese specimens is variable (for example, pronotum can be yellow or black, elytral suture yellow or black) and body size also varies greatly. However, the coloration variability does correspond to the molecular data provided by Damaška et al. (2021). We examined numerous specimens of Cangshanaltica from Taiwan, however, only a few provided molecular sequences, which made a broad molecular analysis impossible, similar to the case of C. castanea. The type series of C. ogatai also does not contain any DNA-grade specimens (H. Suenaga, pers. comm., 2021). An analysis containing both molecular and morphological characters would be, however, necessary to delimit the species. The fauna of the Iriomote island is very similar to Taiwan, both islands even share two species of the edaphic flea beetle genus Clavicornaltica (Suenaga & Yoshida 2016). It is therefore likely that C. ogatai may be distributed in Taiwan. Taiwanese Cangshanaltica diversity is clearly complicated and needs more data to be properly taxonomically resolved. As in the case of C. castanea, we therefore hesitate to describe any new species of Cangshanaltica from Taiwan., Published as part of Damaška, Albert František, Ruan, Yongying & Fikáček, Martin, 2022, The genus Cangshanaltica (Coleoptera: Chrysomelidae: Alticinae): overview, new species, and notes on species complexes, pp. 49-64 in Zootaxa 5219 (1) on pages 61-62, DOI: 10.11646/zootaxa.5219.1.2, http://zenodo.org/record/7408144, {"references":["Takemoto, T. & Suenaga, H.

Material examined: Holotype, male, BRAZIL: Rio de Janeiro (Corcovado), 11.V.1912 // Cerasommatidia arroaei nov. spec. Brèthes (BMNH).

THE PHYLOGENETIC PLACEMENT OF CERASOMMATIDIIDAE STAT. RESTORED WITHIN THE COCCINELLID LINEAGE OF COCCINELLOIDEA The results from our molecular (Fig. 1), morphological (Supporting Information, File S12a–c) and combined data (molecules and morphology) (Fig. 2) analyses strongly and unambiguously support the status of Cerasommatidiidae as a distinct clade at the family level. Morphologically, the monophyly of Cerasommatidiidae is supported by several characters (Fig. 2) (listed in Results) that set cerasommatidiids apart from Eupsilobiidae and other coccinelloid groups. In particular, the ovipositor lacking coxites is unique to this group and has not been found in any other Coccinelloidea. The sister-relationship of Cerasommatidiidae with Mycetaeidae is strongly supported in both the molecular and combined analyses. Yet, only one morphological, homoplastic character was recovered in the combined analyses as supporting this relationship: the mandible with subapical teeth or serrations (9:0). At this point it is difficult to elucidate shared morphological characters between members of these two families. It is noteworthy that the position of Eupsilobiidae differs between the combined and molecular trees. In the molecular tree (Fig. 1) it is recovered as the sistergroup to Coccinellidae with strong support (PP = 1.0), whereas in the combined analysis it forms the sistergroup to the Mycetaeidae + Cerasommatidiidae, although with low nodal support (PP = 0.69) and no corresponding anatomical synapomorphies. The monophyly of Eupsilobiidae is supported by two uncontroverted synapomorphies: aedeagus with penis coiled (38:1) and ovipositor with infundibulumlike structure/sperm duct modified (41:1) and by one homoplastic character: labial mentum with large, triangular, raised area (11:2). The position of Eupsilobiidae within the coccinellid group, as well as the internal family relationships, remains uncertain and ought to be readdressed in future studies. The genus Chileolobius, the only member of Eupsilobiidae represented in the molecular analysis, was supported in our combined data analysis as sister-group to the rest of Eupsilobiidae (‘core Eupsilobiidae’ composed of Eidoreus, EƲolocera, Microxenus and Natalinus). This result could be an artefact of the remaining eupsilobiid exemplars being represented in the combined data analysis by morphological data only. However, Chileolobius is an enigmatic taxon, exhibiting several morphological features shared with all or some Coccinellidae but no other Eupsilobiidae, including frontoclypeal suture absent (6:0), mandibular mola absent or reduced (7:1) and mesotrochantin concealed (28:1). The core eupsilobiids are recovered with strong nodal support (PP = 0.99) and multiple anatomical apomorphies, including antennae composed of ten articles (4:2) and mesotrochantin at least partially exposed (28:0). A closer relationship between Eidoreus and Microxenus, with respect to Chileolobius and Ibicarella, was previously hypothesized by Pakaluk & Ślipiński (1990). Including molecular data for exemplars of core Eupsilobiidae will be the next step to elucidate their relationships with Chileolobius and corroborate the position of Eupsilobiidae among the coccinellid group of families. The results of this study demonstrate the separation of Cerasommatidiidae from Eupsilobiidae, and justify the restoration of this lineage to family status. Cerasommatidiidae are corroborated by both high topological support as the sister-group to Mycetaeidae in the molecular and combined analysis and by their unique morphological features, as outlined above. The relationships between species of Cerasommatidiidae, as revealed by the morphological and combined analyses, justify the recognition of four genera despite an unclear relationship between them. Cerasommatidia in the new sense (including Ibicarella) is a homogeneous group, with species differing only in the structures of the male genitalia, the body proportions and the degree of development of the pronotal border. A sister-relationship recovered for Cerasommatidia + MahaƲelo is based on single homoplastic character: labial palp with palpomere 2 oval, inflated (12:1) and is not strongly supported (PP = 0.83). Similarly, the sisterrelationship of Yamuy with Karumbe has negligible nodal support (PP = 0.47) and no morphological characters to bolster the relationship., Published as part of Arriaga-Varela, Emmanuel, Tomaszewska, Wioletta, Szawaryn, Karol, Robertson, James, Seidel, Matthias, Ślipiński, Adam & Fikáček, Martin, 2023, The resurrection of Cerasommatidiidae, an enigmatic group of coccinelloid beetles (Coleoptera: Coccinelloidea) based on molecular and morphological evidence, pp. 1078-1115 in Zoological Journal of the Linnean Society 197 (4) on pages 1085-1086, DOI: 10.1093/zoolinnean/zlac082, http://zenodo.org/record/7814127, {"references":["Pakaluk J, Slipinski SA. 1990.

CERASOMMATIDIIDAE STATUS RESTORED The BI, ML and MP analyses provide unequivocal support for the monophyly of Cerasommatidia clade and, therefore, we propose the restoration of family status for Cerasommatidiidae. Cerasommatidiidae are divided into four clades corresponding to the four genera proposed here (Fig. 2). The new monotypic genus from Madagascar, MahaƲelo, is recovered as sister-taxon to the Neotropical, type genus of the family, Cerasommatidia (= Ibicarella, synon. nov.), albeit with weak support (PP = 0.83). Morphologically, both genera share the labial palp with oval, inflated second palpomere (12:1). MahaƲelo is characterized by one uncontroverted synapomorphy, scutellar shield invisible (25:1) and one homoplastic feature, abdominal ventrite 1 without postcoxal lines (34:0). Cerasommatidia is supported by one homoplastic character: mesotrochantin at least partially exposed (28:0). Support for the clade comprising the new genera Yamuy and Karumbe is low (PP = 0.47) and lacks supporting morphological features. The new genus Karumbe is supported by the distinctly bordered pronotal base (19:1) and pronotal anterior margin with bordering line crenulate (21:1). Yamuy is characterized by a single uncontroverted synapomorphy, elytral vestiture comprising multiple setal forms (1:1) and one homoplastic character, the abdominal ventrite 1 with postcoxal lines (34:1)., Published as part of Arriaga-Varela, Emmanuel, Tomaszewska, Wioletta, Szawaryn, Karol, Robertson, James, Seidel, Matthias, Ślipiński, Adam & Fikáček, Martin, 2023, The resurrection of Cerasommatidiidae, an enigmatic group of coccinelloid beetles (Coleoptera: Coccinelloidea) based on molecular and morphological evidence, pp. 1078-1115 in Zoological Journal of the Linnean Society 197 (4) on page 1085, DOI: 10.1093/zoolinnean/zlac082, http://zenodo.org/record/7814127

MAHAVELO SZAWARYN, TOMASZEWSKA & ARRIAGA- VARELA GEN. NOV. (FIGS 17, 18, 19C, D, 20C) Zoobank registration: urn: lsid: zoobank. org:act: DF9A1833-7A95-4B99-9148-AFCB9248D39B Type species: MahaƲelo madagasus by present designation. Diagnosis: MahaƲelo is a distinctive genus in Cerasommatidiidae by the lack of a scutellar shield (Fig. 18C, F), and by having the prosternal process provided with single, longitudinal, median carina (Fig. 18D). In general appearance it is most similar to Cerasommatidia, sharing the glabrous appearance of pronotal and elytral surfaces (covered with tiny inconspicuous hairs), pronotum without internal sublateral carinae, and pronotal and elytral surfaces covered with single size punctae (Fig. 18C, F). However, apart from its unique characters, MahaƲelo can also be separated from Cerasommatidia by having the pronotal hind angles with small, oblique indentation to receive the humeral corner of the elytron (Fig. 18C) (absent in Cerasommatidia). Description: Length 1.00 mm, width 0.79 mm. Body short oval and convex, 1.3 times as long as wide. Coloration uniformly brown (Fig. 17A–C). Head (Figs 17D, 18B) with dorsal surface uniformly covered with short fine setae. Clypeus large, rectangular. Frontoclypeal suture distinct but feebly marked, straight.

Antenna (Fig. 18A) approximately 0.35 of length of body; antennal club one-quarter of total antennal length; antennomeres 1–5 much longer than wide, with antennomere 3 longer than antennomere 4 and 5; antennomeres 6–9 less elongate. Eyes comparatively small, moderately prominent, coarsely facetted (Figs 17D, 18B). Maxillary palpomere 1 narrow, elongate; palpomere 2 weakly trapezoidal and somewhat bulbous (Fig. 17E). Galea large, densely setose apically. Lacinia about half as wide as galea, with dense setae at apex and inner margin. Labium with mentum widest near basal third, palpomere 2 large, bulbous, somewhat oval; terminal palpomere short, subquadrate, about as long as penultimate, truncate apically. Prothorax. Pronotum 2.7 times wider than long, widest at base, and strongly convergent anteriorly (Fig. 18C). Anterior pronotal margin narrowly bordered with regular bordering line; base without distinct bordering line. Pronotal sides weakly rounded, narrowly bordered; hind angles with small, oblique indentation to receive humeral corner of elytron. Pronotal disc moderately convex, with uniform sparse fine punctures bearing tiny, thin hairs (Fig. 18C). Prosternum (Fig. 18D) with anterior margin scarcely arcuate posteriorly; prosternal process narrow, at apex about 0.60 of width of procoxal cavity, with long, single median carina but not reaching anterior prosternal margin or apex of prosternal process; prosternal process extending posteriorly to hind level of procoxae. Hypomeron with deep, long and straight antennal grooves. Pterothorax. Mesonotum lacking scutellar shield. Mesoventrite strongly transverse, with intercoxal process smooth, almost flat, with raised anterior border complete (Figs 17G, 18E); 1.2 times as wide as mesocoxal diameter. Metaventrite as long as abdominal ventrites 1 and 2 combined; discrimen absent; anterior margin with bordering carina simple, straight at intercoxal process and widening towards lateral corners (Fig. 18E); central area of metaventrite with fine setiferous punctures. Anterior part of metanepisternum with lateral sub-triangular projection on its external margin. Elytra about as long as wide, with lateral margins invisible from above (Figs 17A, 18F). Surface covered with uniform, small setiferous punctures bearing tiny, thin hairs. Epipleura incomplete but almost reaching elytral apex (Fig. 18G), narrow, with internal bordering line wide, present from the level of mid coxae to apex (Fig. 18E); basal part of epipleuron with short groove corresponding to projection of metanepisternum. Hindwings reduced. Legs. Trochanters produced posteriorly (Fig. 18E). Femora weakly flattened (mid and hind femora more distinctly than fore femora); with g r o o v e s f o r t i b i a e p r e s e n t t h r o u g h o u t w h o l e length. Claws with distinct sharp, subquadrate tooth at base. Abdomen with ventrite 1 with anterior bordering carina below coxae widening laterally (Fig. 18G), absent on intercoxal process; postcoxal lines absent. Male genitalia (Fig. 17H). Aedeagus with penis short and stout, sclerotized, weakly curved, wider near apex, asymmetric, with small acute apical projection. Tegmen moderately large, basal, throne-shaped, weakly sclerotized; tegminal strut short. Female genitalia (Fig. 17J).

(FIGS 6C, D, 7F, I, L, 8A–C, 10A–F, 20A) Zoobank registration: urn: lsid: zoobank. org:act: 57FC49EB-6890-4AF8-BB33-70F66B4D466C Type material: Holotype, male, GRENADA: Balthasar (Windward side), Grenada, W.I., H. H. Smith (BMNH). Paratypes: Same data as for holotype (one male, one female and 1 ex., BMNH; 2 ex, MIZ). Diagnosis: Karumbe geiseri is most similar to K. pakaluki, but it can be distinguished from the later by the wider prosternal process being about 0.90 of width of procoxa (Fig. 10B) (0.67 in K. pakaluki); pronotum with postero-lateral indentation shorter and more rectangular (Fig. 10C) (longer and more oblique in K. geiseri) and by the shape of the aedeagus. From K. brethesi it can be easily distinguished by having dorsal surface of the body covered with setiferous punctures and additional foveolate depressions (in K. brethesi peculiar punctations as in Fig. 9E), the central area of the metaventrite covered with simple setiferous punctures without wide foveate impressions (Fig. 10E), the pronotal disc only weakly concave along the internal lateral carina, and the terminal labial palpomere short and apically rounded, 1.4 times as long as wide (Fig. 10A) (in K. brethesi: elongate and acuminate, 2.2 times as long as wide at base). Description: Body: length 0.90–0.96 mm, 1.25 times as long as wide, 2.0 times as long as high, short oval and moderately convex, brown with yellowish legs, antennae and palpi (Fig. 6C, D).

The New Zealand species of the water scavenger beetle genus Berosus Leach, 1817 are reviewed based on freshly collected material and museum specimens. Four species are recognized: Berosus pallidipennis (Sharp, 1884) widespread in the North and South Islands, B. muellerorum sp. nov. from the eastern part of the North Island, and B. halasi sp. nov. and B. maru sp. nov., both endemic to central part of South Island. The synonymy of B. mergus Broun, 1886 with B. pallidipennis is confirmed and lectotypes for both taxa are designated. The larval morphology of B. pallidipennis and B. muellerorum is briefly discussed. Distributional data of all species are reported and illustrated, indicating a noticeable lack of Berosus species in the northern part of North Island and in Stewart Island and the presence of two rare species in the South Island, east of Southern Alps. An identification key to New Zealand species of the genus is provided

ADAMASTORALTICA BIONDI ET AL., 2020 Type species: Adamastoraltica humicola Biondi et al., 2020. Synonymy: No generic synonyms. Phylogenetic position: Adamastoraltica has been placed in the Aphthonine–Chabrine clade as a sister-group to a clade containing Neocrepidodera, Clavicornaltica and the Chabria group. DamaŠka et al. (2020) found different phylogenetic relationships inside the Aphthonine–Chabrine clade, placing Adamastoraltica as a sister-group to a clade containing Mniophila, Pentamesa and Argopus Fischer, 1824.

APTEROPEDA CHEVROLAT, 1836 Type species: Haltica ciliata Olivier, 1808 = Apteropeda orbiculata Marsham, 1802. Synonymy: No generic synonyms. Phylogenetic position: Apteropeda is a sister-group to the Oriental and Eastern Palaearctic Argopistes, inside the Dibolia group. Diversity and distribution: The genus has four known species, which are distributed only in the Western Palaearctic (Europe and North Africa). Revisions: This genus has never been revised. A synoptic key to all known species is given in Warchałowski (2013). Morphological characteristics: Body 2.0– 3.8 mm long, round-elliptical in dorsal view, convex in lateral view, brown to black or black with metallic lustre. Head nearly hypognathous; frontal ridge present and T-shaped. Antennae 11-segmented without any apical club. Pronotum short, wide, nearly impunctate or densely punctate. Procoxal cavities open posteriorly. Elytra convex, covered by rows of deep punctures. Wingless, humeral calli not developed. Legs relatively short, metatibiae variously modified (e.g. curved or deeply excavated). First metatarsomere elongated. Aedeagus short, bulbous with distinct excavations and furrows in dorsal view. Spermatheca simple; spermathecal duct U-shaped without coils. Ecology: The ecology and host plants of Apteropeda are not well known. Konstantinov & Vandenberg (1996) list many different vascular plants to be previously documented as food sources (e.g. Ajuga L., Cirsium Mill., Plantago L., Satureja L., Veronica L., etc.), but the beetles are usually collected in plant detritus (ČÍŽek & Doguet, 2008). Remarks: In the Western Palaearctic, the genus Apteropeda is somewhat similar to Sphaeroderma Stephens, 1831, from which it can be distinguished by having regular rows of punctures on the elytra(Palaearctic Sphaeroderma has confusedly punctate elytra).In general, Apteropeda is similar to the genus Argopistes, from which it can be separated by having nearly hypognathous head (in Argopistes, head is opistognathous) and by having moderately broadened metafemora and long metatibia (in Argopistes, metafemora are extremely enlarged and metatibiae shortened and usually strongly modified)., Published as part of Damaška, Albert František, Konstantinov, Alexander & Fikáček, Martin, 2022, Multiple origins of moss-inhabiting flea beetles (Coleoptera: Chrysomelidae): molecular phylogeny, overview of genera and a new genus from Africa, pp. 647-676 in Zoological Journal of the Linnean Society 196 on pages 670-671, DOI: 10.1093/zoolinnean/zlab112, http://zenodo.org/record/7196247, {"references":["Warchalowski A. 2013.

MNIOPHILOSOMA WOLLASTON, 1854 (FIG. 6) Type species: Mniophilosoma laeve Wollaston, 1854. Synonymy: No generic synonyms. Phylogenetic position: The phylogenetic placement of Mniophilosoma has not been sufficiently resolved in our analysis; with a low support, it was revealed as a member of the Aphthonine–Chabrine clade. Diversity and distribution: The two known species of the genus are distributed in the Macaronesian islands of the Azores and Madeira. These species are similar and differ mostly in morphological details in elytral microsculpture and genitalia. Gillerfors (1986) proposed a hypothesis that the two species are closely related. Revisions: The genus contains two species only and was never revised. Diagnoses of both species were provided by (Gillerfors, 1986). Morphological characteristics: Body small, around 1.5–2.0 mm long, elliptical in dorsal view, convex in lateral view. Body surfaces darkened or black with metallic lustre. Head nearly hypognathous, frontal calli well developed. Antennae with 11 antennomeres, pale yellowish. Apical antennomeres tending to form a slightly developed antennal club. Pronotum convex, lacking any grooves or impression, impunctate. Procoxal cavities open posteriorly. Posterior process of proventrite process strongly punctated. Elytra convex, sparsely punctate or microsculptured. Wings and humeral calli not developed. Legs pale, metafemora not strongly widened. Aedeagus long and parallelsided, spermathecal duct without coils. Ecology: The species are enigmatic and only a few papers comment on their biology. In the Azores, Mniophilosoma obscurum Gillerfors, 1986 was collected from Sphagnum L. moss cushions under Ericaceae shrubs (Gillerfors, 1986). The Madeiran species, M. laeve, inhabits moss cushions in wet subtropical laurisilva forests typical for Macaronesia (Prada et al., 2009). Mniophilosoma laeve is a common species in Madeira and can be easily collected. Interestingly, the beetles are slow in their movement and are almost unable to jump (DamaŠka, personal observation). Remarks: The genus is somewhat similar to the European Mniophila, from which it was diagnosed above., Published as part of Damaška, Albert František, Konstantinov, Alexander & Fikáček, Martin, 2022, Multiple origins of moss-inhabiting flea beetles (Coleoptera: Chrysomelidae): molecular phylogeny, overview of genera and a new genus from Africa, pp. 647-676 in Zoological Journal of the Linnean Society 196 on page 666, DOI: 10.1093/zoolinnean/zlab112, http://zenodo.org/record/7196247, {"references":["Gillerfors G. 1986.

IVALIA JACOBY, 1887 (FIG. 4) Type species: Ivalia viridipennis Jacoby, 1887, designated by Maulik (1926). Synonyms: Ancyloscelis Ogloblin, 1930, synonymized by Scherer (1969); Amphimeloides Jacoby, 1887, synonymized by Duckett et al. (2006); Taizonia Chen, 1934, synonymized by Duckett et al. (2006); Schereria Medvedev, 1984, synonymized by Gruev & Askevold, (1988). Phylogenetic position: The genus belongs to the Chabria group, based on both our analyses and DamaŠka et al. (2021); the latter study revealed polyphyly of the genus, therefore, the genus will require revision. Diversity and distribution: There are 86 known species of Ivalia; most species were catalogued by Nadein (2013a) listing 67 species.An additional two species were described by Medvedev (2016) and a further species by Takizawa & Konstantinov (2018). New species from the Philippines were described by DamaŠka et al. (2020) and from Japan by Takemoto & Suenaga (2021). The genus is distributed from India and the Himalayas to central China, Japan and southwards to Australia. Most species are described from high mountain ranges (Himalayas, Mt. Kinabalu and New Guinea). Revisions: The genus has not been revised recently. Duckett et al. (2006) redescribed the genus, described its larva and established new synonyms; fauna of Australia was revised by Nadein (2013a). Synoptic keys were presented by Medvedev (2009) for Indochina and Yang et al. (2015) for China and Taiwan. Morphological characteristics: The morphological features diagnosing Ivalia were proposed by Duckett et al. (2006) and should possibly be revised based on DamaŠka et al. (2021). The genus consists mainly of small to large flea beetles (1.5–5.0 mm). General body shape oval to rounded, convex in lateral view. Body colour from black, with or without metallic lustre, to yellow basic colour and variable pattern or dark elytral and pronotal spots. The majority of species are wingless. Head nearly hypognathous, antennal shape from long and slender to relatively short, with distal antennomeres somewhat widened, frontal calli poorly developed (Nadein, 2013a; Takizawa & Konstantinov, 2018). Pronotum usually about twice as wide as long, convex, on apical margins sometimes with rounded lobes visible anterolaterally. Pronotal margin with a setiferous pore situated in the apical half of the pronotal length. Procoxal cavities widely open posteriorly.The anterior process of the metaventrite expanding between the mesocoxae partially covering the mesoventrite, similar to that of Clavicornaltica and Cangshanaltica. Metaventral intercoxal process surface excavated, forming a horseshoe-shaped structure (as in Cangshanaltica). Metafemora strongly curved in many species, some described species bearing straight metafemora (Takizawa & Konstantinov, 2018). Metatibiae with a long apical spur, proximal metatarsomere elongated. Vaginal palpi fused basally, with apices widely separated. Spermatheca simply formed, with duct not bearing coils. Aedeagus usually simple with long, wide and flat apex. Ecology: In most species the ecology is not known, but all species with known biology are associated with mosses and known larvae feed on mosses (Duckett et al., 2006; Takizawa & Konstantinov, 2018; Takemoto & Suenaga, 2021). The majority of known species are described from high elevations up to 3500 m, but mid-elevation and lowland species are known as well (DamaŠka & Aston, 2019; Takemoto & Suenaga, 2021). Remarks: Diagnoses from Clavicornaltica and Cangshanaltica were mentioned above. Ivalia is also similar to Phaelota Jacoby, 1887, from which it can be distinguished by the morphology of procoxal cavities, closed posteriorly in Phaelota, open in Ivalia (Konstantinov et al., 2013)., Published as part of Damaška, Albert František, Konstantinov, Alexander & Fikáček, Martin, 2022, Multiple origins of moss-inhabiting flea beetles (Coleoptera: Chrysomelidae): molecular phylogeny, overview of genera and a new genus from Africa, pp. 647-676 in Zoological Journal of the Linnean Society 196 on page 663, DOI: 10.1093/zoolinnean/zlab112, http://zenodo.org/record/7196247, {"references":["Duckett CN, Prathapan KD, Konstantinov AS. 2006.

ANDERSONALTICA LINZMEIER & KONSTANTINOV, 2012 (FIG. 3) Type species: Andersonaltica pecki Linzmeier & Konstantinov, 2012. Synonymy: No generic synonyms. Phylogenetic position: The genus belongs to the mossinhabiting clade in the Monoplatus group. Our analysis revealed its sister-group as Ulrica Scherer, 1962. D i v e r s i t y a n d d i s t r i b u t i o n: S e v e n s p e c i e s o f Andersonaltica are known to date. They occur in Central America (Guatemala, Honduras and Mexico) and in the West Indies (Dominican Republic). Revisions: Apart from five species described within the genus (Linzmeier & Konstantinov, 2012), two additional species were described recently from the Dominican Republic (Konstantinov et al., 2020). Morphological characteristics: The beetles are small, 1.76–2.07 mm long and 1.07–1.17 mm wide. Head with antennal calli small, widely separated anteriorly, slightly raised above surface of vertex, generally nearly indistinguishable; without supracallinal, orbital, supraorbital, suprantennal and frontolateral sulci. Suprafrontal sulcus deep. Antennae with 11 antennomeres; of which seven to 11 form a tight club; antennomere 6 generally shortest, wider than long. Pronotum without antebasal transverse impression; with anterior margin straight, posterior margin nearly straight to slightly concave, sides parallel or slightly convex. Anterior setiferous pores of pronotum present, facing laterally. Posterior setiferous pores facing dorsolaterally or dorsally. Pronotal disc raised with two elongate tubercles anteromedially with shallow groove in between. Elytral surface shiny, deeply punctured, with dense pilosity. Punctures forming nine striae (not counting short scutellar and marginal striae). Basal calli generally well developed. Humeral calli absent or poorly developed. Impression between basal and humeral calli ending deeper behind basal callus. Metatibia nearly straight in lateral view, slightly curved in dorsal view. Apex of outer lateral dorsal ridge with three to five denticles. Inner lateral dorsal ridge with one to three denticles at apex. Metatibial spur short. Metatibia with or without preapical tooth situated before tarsal insertion. Outer and inner dorsal margins of metatibia not connected at apex. Ecology: All Central American species were sifted from (cloud) forest leaf-litter at various elevations. West Indian species are known from moss cushions at about 1200 to 2600 m above sea level. Remarks: Andersonaltica may be separated from many genera of Monoplatina in having antennae with a compact club (compared to mostly filiform antennae in other Monoplatina). Andersonaltica is similar to Apleuraltica Bechyné, 1956 and can be differentiated from it by the following characters: five apical antennomeres forming a compact club (Apleuraltica has the five apical antennomeres clearly separated from each other, not forming a compact club); outer and inner dorsal margins of metatibia not connected at apex by a ridge (Apleuraltica has outer and inner dorsal margins of metatibia connected at apex by a ridge, before tarsomere insertion).

CLAVICORNALTICA SCHERER, 1974 (FIG. 4) Type species: Clavicornaltica besucheti Scherer, 1974. Synonymy: No generic synonyms. Phylogenetic position: In our analysis, Clavicornaltica has a long branch suggesting its rapid evolution, and making its phylogenetic placement difficult to reveal. Our analysis revealed Clavicornaltica as a member of the Aphthonine–Chabrine clade, with Neocrepidodera as the sister-clade, albeit with low support (P = 0.64). DamaŠka et al. (2020) revealed Clavicornaltica to form a moderately supported clade with Neocrepidodera and Orestia Chevrolat in Dejean, 1836. Diversity and distribution: To date, 27 species of Clavicornaltica are described from various countries across South-East Asia. The genus is distributed from Nepal, India and Sri Lanka to the Solomon Islands, one known species lives in Australia and the northern boundary of the range is in Japan and China. Because the treatment of Clavicornaltica and the dissection of genitalia are extremely difficult, older authors used a wide species concept, treating the observed variation as unnamed forms. Modern studies based on genitalia morphology have shown that this approach is incorrect and the true diversity of Clavicornaltica is huge, probably reaching hundreds of undescribed species. Revisions: The complete fauna of Clavicornaltica was reviewed by Medvedev (1996); a long-term study on the genus was also performed by Manfred Döberl, but its results were never published. Konstantinov & Duckett (2005) described new species and provided a key for species distributed in southern China and Vietnam, Suenaga & Yoshida (2016) summarized the known fauna of Japan and Taiwan with descriptions of more new species. Other studies on Clavicornaltica only describe single new species, without providing a wider comparison or updated identification keys. Morphological characteristics: Clavicornaltica specimens, being the smallest among leaf beetles, are characterized by very small body size (0.7–1.5 mm). Body generally extremely compact, round, pronotum and elytra strongly convex in lateral view. Head hypognathous, triangular in frontal view, in some species with developed frontal callosities and frontal ridge. Antennae short; antennomeres 5–11 strongly widened, forming a distinct antennal club. The shape of the antennal club varies from relatively elongated, not welldefined one to strongly compact and rounded (the latter is present in most species). Pronotum strongly convex, legs short. Metatibiae extremely widened. Procoxal cavities open posteriorly. Mesoventrite completely invisible in ventral view, entirely covered by an elongated anterior metaventral process. First abdominal ventrite with an anterior process reaching the space between metacoxae with distinct ridge surrounded by deep punctures. Elytra strongly convex, usually covered with poorly visible punctures. Males of most species winged; females of all known species flightless and wingless. The morphology of both male and female genitalia is extremely diverse and seems to be one of the only morphological characteristics useful for species-level diagnostics. Aedeagus moderately sclerotized to nearly completely unsclerotized; in many species, basal opening of the aedeagus strongly elongated, forming up to a half of the aedeagus length. Aedeagi of many species strongly curved in lateral view or, on the other hand, strongly elongated, in extreme cases longer than abdomen stretching up to prothorax. The morphological diversity of spermatheca is also high; the shape of the pump and receptacle varies from a cylindrical pump with distinctly separated, short and slender receptacle, to bow-like spermatheca with receptacle and pump fused. Duct usually short, but strongly coiled in many species; on the other hand, the duct is extremely shortened and nearly not present in some species. Vaginal palpi usually long, slender and parallel. Ecology: Little information is available about Clavicornaltica ecology. The beetles are usually collected by sifting, males are sometimes detected in flight-intercept traps or malaise traps. Konstantinov et al. (2013) mentions some species to be associated with mosses, which is the reason why we list the genus here. However, the majority of species are probably associated with decaying material and can be collected by sifting forest leaf-litter without mosses. Therefore, we treat the genus as leaf-litter-inhabiting in the phylogenetic study. Remarks: The unique morphology of Clavicornaltica makes the genus clearly distinguishable from all other flea beetle genera distributed in the Old World. The only genus similar to Clavicornaltica is Kiskeya Konstantinov & Chamorro-Lacayo, 2006 distributed in the West Indies. However, the two genera can be distinguished by different shape and structure of antennae and the antennal club, as well as by the shape of the metaventrite (Kiskeya does not have the metaventral process covering the mesoventrite in the space between the mesocoxae) and procoxal cavities (in Kiskeya, procoxal cavities are closed). Because of the morphological uniformity and strong morphological difference from other genera, no hypothesis on the relationships between Clavicornaltica and other flea beetle genera has been proposed to date., Published as part of Damaška, Albert František, Konstantinov, Alexander & Fikáček, Martin, 2022, Multiple origins of moss-inhabiting flea beetles (Coleoptera: Chrysomelidae): molecular phylogeny, overview of genera and a new genus from Africa, pp. 647-676 in Zoological Journal of the Linnean Society 196 on pages 660-661, DOI: 10.1093/zoolinnean/zlab112, http://zenodo.org/record/7196247, {"references":["Damaska AF, Mohagan DJ, Fikacek M. 2020.

BENEDICTOIDES GEN. NOV. (FIG. 5) Z o o b a n k r e g i s t r a t i o n: u r n: l s i d: z o o b a n k. org:act: 0D64E9D0-9F23-447C-963D-775BB7995B67 Type species: Benedictoides munclingeri sp. nov.. Phylogenetic position: Benedictoides is placed in the Manobia group, with Benedictus revealed as its sistergenus. The morphologically similar Neotropical genus Aulonodera is not closely related to Benedictoides. Diversity and distribution: The single species is found in Cameroon, western Africa. Description: Body convex, elongate, 1.4 mm long, 0.75 mm wide in dorsal view, 0.5 mm high in lateral view. Ventral surfaces and legs brown without metallic lustre, dorsal surfaces dark blackish brown. Head: (Fig. 5) Nearly prognathous, triangular, slightly protruded anteriorly. Vertex impunctate. Supraorbital, orbital, suprafrontal, supraantennal and supracallinal sulci deep and well developed. Antennal calli well developed, oblique, rhomboidal. Frontolateral sulci feebly developed. Supraorbital pore large, circular, placed nearly equally distant from eye as diameter of eye from dorsal view. Orbit large, equally wide as diameter of eye in lateral view; impunctate, eyes projecting laterally. Frontal ridge slender, sharply projecting. Frons nearly impunctate with several scattered setae. Clypeus darkened. Labrum with a longitudinal row of four setae. Antennae with 11 antennomeres, antennomeres 9–11 rounded oval, equally wide, distinctly wider than antennomeres 2–7. Thorax: Pronotum (Fig. 5) round, strongly convex in lateral view, impunctate, strongly narrowed basally by a deep antebasal transverse impression. Pronotal impression impunctate, reaching pronotal side. Anterolateral angles of pronotum extremely wide, projecting laterally, triangular, bearing a setiferous pore with a long seta. Posterolateral angles of pronotum small, sharp. Pronotal base straight, with a sharp edge. Procoxal cavities widely open posteriorly. Scutellum rounded-triangular. Elytra convex, punctate; punctures arranged in regular rows. Basal elytral margin widely rounded, elytral apices narrowed posteriorly. Lateral sides of elytra slightly produced laterally, lateral elytral margin and pleura not visible from dorsal view. Epipleura wide in basal parts, strongly narrowing towards apex. Humeral calli and wings absent. Metaventrite with a short, wide process extending about half of the space between the mesocoxae, not covering mesoventrite. Legs brown. Protibiae widened towards apex and slightly curved laterally. Metatibiae slightly widened apically, not bearing any distinct apical spine. Pro- and mesotarsi elongated; protarsi as long as a quarter of the protibiae, mesotarsi nearly as long as two-thirds of the mesotibiae. Metatarsomere 1 elongated, as long as metatarsomeres 2 and 3 combined. Abdomen: Abdominal ventrites feebly punctate. First abdominal ventrite with a wide process reaching the space between the metacoxae. Generic diagnosis: Benedictoides is distinct among the Afrotropical fauna. It is only similar to the Afrotropical genus Celisaltica Biondi, 2001, sharing the lack of wings, somewhat elongated body, open procoxal cavities and apical antennomeres slightly widened. However, Benedictoides can be easily distinguished from Celisaltica by having a deep pronotal antebasal transverse impression and impunctate pronotum. The new genus is also similar to Manobia, from which it can be separated by lack of humeral calli (in Manobia, extremely projecting humeral calli are present). When compared to the fauna worldwide, Benedictoides is similar to the related Asian moss-inhabiting genus Benedictus. It also shares general body shape and many characters with the Neotropical genus Aulonodera Champion, 1918, but which is not related. Benedictoides shares the following characters with Benedictus: wings absent; procoxal cavities open posteriorly; pronotum impunctate with a deep, antebasal, transverse impression; well-developed frontal calli; elytra deeply punctate by deep punctures arranged in rows; and widely projected anterior pronotal angles. However, the new genus differs from Benedictus in the following characters (Fig. 4): (1) pronotum narrow, much narrower than basal part of elytra (in Benedictus, pronotum is usually as wide or only slightly narrower than basal part of elytra); (2) basal margin of elytra rounded, not forming a distinct edge between basal and lateral elytral margin (in Benedictus, basal elytral margin is straight, basal and lateral margin of elytra forming an edge); (3) pronotum and elytra extremely convex (in Benedictus, pronotum and elytra are not extremely convex or even flat in some species); (4) pronotal antebasal transverse impression reaching pronotal side (in Benedictus, pronotal antebasal transverse impression usually ends before pronotal side, in many species surrounded by short basal longitudinal impressions); and (5) antennomeres 9–11 rounded oval, equally wide, distinctly wider than antennomeres 2–7 (in Benedictus, antennomeres are widening gradually from basal to apical, with antennomere 11 the widest and antennomeres are subtriangular, widening apically). Benedictoides shares the following characters with Aulonodera: wings absent; pronotum narrower than basal part of elytra; basal elytral margin rounded, lacking an edge between basal and lateral margins; ovalrounded distal antennomeres; and antebasal pronotal transverse impression reaching pronotal pleura. The new genus differs from Aulonodera by having elytra punctate with deep punctures arranged in rows (in Aulonodera, elytra are nearly impunctate); and procoxal cavities widely open posteriorly (in Aulonodera, procoxal cavities are partially closed posteriorly). Ecology: The only species, here described, was collected by sifting moss cushions in a tropical montane cloud forest (Fig. 6). Etymology: The name Benedictoides means ‘similar to Benedictus ’ and refers to the strong similarity between these two moss-inhabiting flea beetle genera. The name is masculine., Published as part of Damaška, Albert František, Konstantinov, Alexander & Fikáček, Martin, 2022, Multiple origins of moss-inhabiting flea beetles (Coleoptera: Chrysomelidae): molecular phylogeny, overview of genera and a new genus from Africa, pp. 647-676 in Zoological Journal of the Linnean Society 196 on pages 657-658, DOI: 10.1093/zoolinnean/zlab112, http://zenodo.org/record/7196247

CANGSHANALTICA KONSTANTINOV ET AL., 2013 (FIG. 4) Type species: Cangshanaltica nigra Konstantinov et al., 2013. Synonymy: No generic synonyms. Phylogenetic position: Cangshanaltica has recently been revealed as a member of the Chabria group, together with the moss-inhabiting genus Ivalia and the leaf-surfaceliving genera Chabria Jacoby, 1887, Chabriosoma Chen, 1934 and Sutrea Baly, 1876 (DamaŠka et al., 2020). In our present study, the sister-group of Cangshanaltica is Ivalia (pp = 0.95). However, a larger phylogenetic analysis of the Chabria group revealed Cangshanaltica as a sister-group of a clade containing mostly winged genera, namely Chabria, Chabriosoma, Sutrea and Parathrylea Duvivier, 1892 (DamaŠka et al., 2020). Revisions: The genus was recently described (Konstantinov et al., 2013) as monotypic, with additional species described since (DamaŠka & Konstantinov, 2016; Konstantinov et al., 2016; DamaŠka & Aston, 2019; Ruan et al., 2020; Takemoto & Suenaga, 2021). Diversity and distribution: Seven species have been described; descriptions of four additional species are in preparation (DamaŠka et al., in prep.). The genus is distributed in the Himalayan foothills (China and Thailand), the Philippines, the Chinese coast from Hong Kong to Zhejiang, in Taiwan (DamaŠka et al., 2021) and in the Ryukyu Archipelago (Takemoto & Suenaga, 2021). Morphological characteristics: Body generally ovate to round in dorsal view, strongly convex in lateral view, head nearly hypognathous. Antennal calli indistinct. Antennae with 11 antennomeres; apical antennomeres tend to be widened. Antennomere 7 bears a distal protrusion. A remarkably similar protrusion was recently discovered in a flightless galerucine Prathapanius fortis Viswajyothi & Clark, 2020. Pronotum short, convex, with an anterolateral setiferous pore placed nearly in the midlength of the lateral pronotal margin. Procoxal cavity open posteriorly. Mesoventrite entirely covered by the anterior process of the metaventrite in the area between the mesocoxae. The surface of the anterior metaventral process is strongly modified with distinctly projecting lateral margin, forming a specific ‘horseshoe-like’ shape. Elytra convex, usually covered with scattered feeble punctures. Legs robust, metatibiae slightly or strongly curved. First metatarsomere elongated. First abdominal ventrite with an elevated ridge, surrounded by deep punctures, exceeding as an anterior abdominal process between metacoxae. Aedeagus usually simple, long, with somewhat arrow-like apex. Spermathecal duct without coils. Vaginal palpi fused basally. Ecology: Unlike other moss-inhabiting flea beetle genera, the ecology of Cangshanaltica is well documented. The montane species (C. mindanaoensis DamaŠka et al., 2020, C. nigra and C. siamensis DamaŠka & Konstantinov, 2003) live in moss cushions in montane cloud forests or close to the tree line. Cangshanaltica sprynari DamaŠka & Aston, 2019 and C. fuanensis Ruan et al., 2020, on the contrary, were found at low elevations. Individuals of C. sprynari were documented to be active only for few days during the year, usually after rains, walking over substrate covered by thin layers of mosses (instead of inside of moss cushions). Cangshanaltica nigra is documented to feed on tissues of Hypnum Hedw. moss, as documented by the dissection of its gut content; C. sprynari feeds on Fissidens Hedw., which was also demonstrated by dissection (Konstantinov et al., 2013; DamaŠka & Aston, 2019). Ruan et al. (2020) described the larva and ecology of C. fuanensis, including the length of the larval development and egg-laying ecology. Remarks: Externally, Cangshanaltica is s i m i l a r t o I v a l i a, s h a r i n g m o s t o f i t s g e n e r a l morphological features, i.e. round and convex body, curved metatibiae and the horseshoe-like anterior metaventral process. The main diagnostic characters between Cangshanaltica and Ivalia are: the anterolateral pronotal setiferous pore situated nearly in the midlength of the pronotal margin (in Ivalia, it is placed anteriorly, usually with an anterior lobe placed before the pore); seventh antennomere is modified, bearing a distal protrusion (in Ivalia, seventh antennomere does not bear such a protrusion). Members of Ivalia are also usually more ovate (Cangshanaltica is usually more rounded) and less convex in body shape., Published as part of Damaška, Albert František, Konstantinov, Alexander & Fikáček, Martin, 2022, Multiple origins of moss-inhabiting flea beetles (Coleoptera: Chrysomelidae): molecular phylogeny, overview of genera and a new genus from Africa, pp. 647-676 in Zoological Journal of the Linnean Society 196 on pages 659-660, DOI: 10.1093/zoolinnean/zlab112, http://zenodo.org/record/7196247, {"references":["Konstantinov A, Chamorro ML, Prathapan KD, Ge SQ, Yang XK. 2013.

MNIOPHILA STEPHENS, 1831 (FIG. 6) Type species: Haltica muscorum Koch, 1803. Synonymy: This genus has no generic synonyms. Phylogenetic position: Our Bayesian analysis revealed Mniophila as a sister-group to Pentamesa in the Pentamesa group. This result corresponds with Bayesian and maximum likelihood analyses in DamaŠka et al. (2021). The maximum likelihood analysis performed here reveals Mniophila as a sister to the leaf-litter-inhabiting Patagonian Aulonodera with a low support (BS = 32), which we consider as less probable. Diversity and distribution: Four species are known so far. The genus is distributed in Europe and adjacent areas around the Black Sea coast. Differences between the species are subtle and molecular treatment seems necessary to reveal the species status of various populations., Published as part of Damaška, Albert František, Konstantinov, Alexander & Fikáček, Martin, 2022, Multiple origins of moss-inhabiting flea beetles (Coleoptera: Chrysomelidae): molecular phylogeny, overview of genera and a new genus from Africa, pp. 647-676 in Zoological Journal of the Linnean Society 196 on page 665, DOI: 10.1093/zoolinnean/zlab112, http://zenodo.org/record/7196247, {"references":["Damaska AF, Konstantinov A, Lee CF, Ruan Y, Mohagan DJ, Fikacek M. 2021.

KISKEYA KONSTANTINOV & CHAMORRO- LACAYO, 2006 (FIG. 3) Type species: Kiskeya baorucae Konstantinov et al., 2006. Synonyms: No generic synonyms. Phylogenetic position: We found Kiskeya deeply nested inside the ‘Disonychine–Monoplatine’ clade, belonging to the Disonycha generic group, where it stands as a sister-lineage to all its remaining members. Diversity and distribution: Five species of Kiskeya are known to date. The genus is endemic to the West Indies. Revisions: New species with keys provided are described in Konstantinov & Konstantinova (2011) and Konstantinov et al. (2020). Morphological characteristics: Body extremely small (0.8–1.1 mm), strongly ovate and extremely convex in lateral view. Head hypognathous. Antennae with only nine antennomeres, short, four apical antennomeres strongly widened, forming a compact and rounded antennal club. Pronotum strongly convex, bearing a pair of basal setiferous pores on lateral margin. Elytra extremely convex, round, nearly lacking punctures. Procoxal cavities closed posteriorly. Metaventral process short, triangular, not covering the mesoventrite in the space between the mesocoxae. Metafemora strongly widened, metatibiae slightly curved. The first abdominal ventrite bears a distinct ridge surrounded by deep punctures, with an anterior process reaching the space between metacoxae. Aedeagus simple and parallel-sided, curved in lateral view. Spermatheca subcylindrical, pump wide and relatively long. Spermathecal duct extremely short. Ecology: Specimens of Kiskeya were collected in cloud forests by sifting or individually from moss cushions. Larvae were also collected in the same moss samples (Konstantinov, unpubl. data). Remarks: The morphology of Kiskeya represents an extreme specialization for edaphic lifestyle, making Kiskeya completely different from all known Neotropical alticine genera. In worldwide fauna, the only similar genus is the Asian genus Clavicornaltica, which is diagnosed from Kiskeya above., Published as part of Damaška, Albert František, Konstantinov, Alexander & Fikáček, Martin, 2022, Multiple origins of moss-inhabiting flea beetles (Coleoptera: Chrysomelidae): molecular phylogeny, overview of genera and a new genus from Africa, pp. 647-676 in Zoological Journal of the Linnean Society 196 on pages 663-664, DOI: 10.1093/zoolinnean/zlab112, http://zenodo.org/record/7196247, {"references":["Konstantinov AS, Chamorro-Lacayo ML. 2006.

PHAELOTA JACOBY, 1887 (FIG. 4) Type species: Phaelota semifasciata Jacoby, 1887. Synonymy: This genus has no generic synonyms. Phylogenetic position: Unknown. A possible placement in the Chabria group has been discussed, but no molecular or morphological phylogenetic analysis has been published to justify this. Diversity and distribution: So far, 16 species of Phaelota are known (Ruan et al., 2017). The genus is found mainly in India and Sri Lanka. One species was described from Borneo (Konstantinov, 2008). Revisions: The fauna of southern India and Sri Lanka was recently revised by Prathapan & Viraktamath (2009). Morphological characteristics: Body large, 2.5 to 5.5 mm long, oval to round in dorsal view, moderately convex in lateral view, colour variable. Head hypognathous, partially retracted into prothorax. Antennal calli well developed, triangular, separated from vertex and from each other by deep impressions. Frontal ridge wide and flat. Antennae with 11 antennomeres, not widened or forming any apical club. Pronotum wide, with a feebly developed a n t e b a s a l t r a n s v e r s e i m p r e s s i o n, s u r r o u n d e d by two short longitudinal impressions. Procoxal cavities closed posteriorly; in Phaelota sindhoori Prathapan & Viraktamath, 2004, procoxal cavities narrowly open. The intercoxal proventral process wide. Elytra narrowing towards apex, with rows of slightly developed punctures. Legs long; all coxae with a triangular posterior denticle. Aedeagus simple, slightly curved in lateral view. Spermatheca simple, with a long pump and bulbous receptacle; spermathecal duct without coils. Vaginal palpi fused basally, and parallel. Ecology: The genus contains both moss-inhabiting and leaf-surface-living species (Konstantinov et al., 2013; Ruan et al., 2017). Prathapan & Viraktamath (2009) report that at least three leaf-surface-living Indian species feed on ferns. It is likely that various species from the genus feed on various food sources; however, the ecology of Phaelota needs more research to be resolved. Remarks: The genus is similar to Chabria and Acrocrypta Baly, 1862. It can be separated from Chabria, by having closed procoxal cavities (procoxal cavities are open in Chabria). From Acrocrypta, the genus differs by having a wide intercoxal proventral process and elytral punctures in rows (in Acrocrypta, the intercoxal proventral process is narrow and elytra are confusedly punctured)., Published as part of Damaška, Albert František, Konstantinov, Alexander & Fikáček, Martin, 2022, Multiple origins of moss-inhabiting flea beetles (Coleoptera: Chrysomelidae): molecular phylogeny, overview of genera and a new genus from Africa, pp. 647-676 in Zoological Journal of the Linnean Society 196 on pages 668-669, DOI: 10.1093/zoolinnean/zlab112, http://zenodo.org/record/7196247, {"references":["Ruan YY, Konstantinov AS, Prathapan KD, Yang XK. 2017.
