Thorictus bengalensis Háva & Chakrovorty sp. nov. from West Bengal, India is described, illustrated and compared with similar Indian species. Trichomyrmex destructor (Jerdon, 1851) (Hymenoptera, Formicidae, Myrmicinae, Crematogastrini) is the host ant species. The interaction has been studied from an urban rooftopgarden. The species Thorictus wroughtoni Wasmann, 1912 stat. nov. is elevated from subspecies to a separate species. The check list of Thorictus species recorded from India is added. Additionally, a Goblin spider species, Gamasomorpha sp. Karsch, 1881 (Arachnida: Araneae: Araneomorphae: Oonopidae) was observed to be inhabiting the same nest. [ABSTRACT FROM AUTHOR]

Epepeotes luscus luscus (Fabricius, 1787) is newly recorded in Cambodia and Singapore, and Epepeotes uncinatus uncinatus Gahan, 1888 is newly recorded in Bangladesh. Images of the type and other significant specimens are provided for 23 taxa, mainly for the first time. [ABSTRACT FROM AUTHOR]

Type specimens of Oedionychina Chapuis, 1875 described by Fabricius from the Kiel collection are examined and illustrated. Lectotypes are designated for the following species: Chrysomela albicollis Fabricius, 1787; Chrysomela nobilitata Fabricius, 1787; Chrysomela quadrifasciata Fabricius, 1787; Chrysomela quadriguttata Fabricius, 1781; Galleruca atomaria Fabricius, 1801; Galleruca decemguttata Fabricius, 1801; Galleruca fasciata Fabricius, 1798; Galleruca humeralis Fabricius, 1801; Galleruca lunata Fabricius, 1801; Galleruca nitida Fabricius, 1801; Galleruca obsoleta Fabricius, 1801; Galleruca petaurista Fabricius, 1801; Galleruca quadrinotata Fabricius, 1798; Galleruca sellata Fabricius, 1801. The species status is restored for Chrysomela quadriguttata Fabricius, 1781 and Alagoasa areata (Germar, 1824) comb. nov. The following new combinations are proposed: Phenrica quadriguttata (Fabricius, 1781), Asphaera nitida (Fabricius, 1801), Phenrica obsoleta (Fabricius, 1801), Alagoasa areata areata (Germar, 1824), Alagoasa areata decempunctata (Latreille, 1833), Alagoasa areata escuintla Bechyné, 1955, Alagoasa areata macromela Bechyné, 1958, Alagoasa areata praecessa Bechyné, 1959, Alagoasa areata recuperata Bechyné, 1959; all comb. nov. New placement: Galleruca avicenniae Fabricius, 1792 is removed from Alticini and placed in Galerucini incertae sedis; Galleruca trifasciata Fabricius, 1801 is removed from Chrysomelidae and placed in genus Ora Clark, 1865 (Scirtidae Fleming, 1821).

Elytroatra Daccordi, status novus, and description of E. caroli, species nova, from Bolivia with brief notes on some related neotropical genera of Chrysomelinae Doryphorini (Coleoptera: Chrysomelidae). Elytroatra Daccordi 2008 is raised to genus level from its original status as subgenus of Proseicela Chevrolat 1836. The new status is proposed in consideration of the wide clypeus, almost smooth, the supra-orbital area strongly raised, with the eyes placed at its vertex so that the head appears notably transversally widened, absence of metathoracic wings, elytral shape elongate with a narrow apical angle (nearly 60°), for the presence of a wide, continuous, bulgy elytral lateral callus, narrow and elongated femora and particularly narrow and elongated tibiae. Type species of the genus is Elytrosphaera melas Jolivet 1950. Elytroatra caroli sp. n. is here described from the same biogeographic region of the Bolivian Yungas. and is the second known species of the genus. Elytroatra caroli sp. n. can be separated at first glance from its relative E. melas for its thoroughly shining black coloration, absence of two symmetrical pores at sides of pronotal disc, the shape of aedeagus with the apex narrower and elongated and shorter and less arcuate tegmen.

Trichomyia is a cosmopolitan genus, and it is the only genus of Trichomyiinae to include extant species. In recent years, an increasing number of species belonging to the genus have been described, particularly from the Neotropics. However, phylogenetic studies of these species are lacking. In addition, few studies have focused on this group, and none has focused on it exclusively, making it difficult to classify objectively the high diversity known today. Herein, we present the first phylogenetic analysis of Trichomyia. We studied specimens from all continents to propose a phylogeny and used it as the basis of a new classification. Two clades proposed as genera were recovered. The canonical informal classification of Trichomyia into Groups A and B is discussed, and Gondwanotrichomyia is assigned a new status. Although we do not propose a subgeneric classification for Trichomyiinae, we provide some comments on the previously proposed subgenera based on our phylogeny. In addition, we report on the expanded distribution of Trichomyia festiva , Trichomyia gabia and Trichomyia imarui. [ABSTRACT FROM AUTHOR]

Cetoniine genus Hemiprotaetia Mikšič, 1963 and subgenus of Protaetia Burmeister, 1842 -Chalcoprotaetia Mikšič, 1963 are studied. Study of representatives of both taxa, especially aedeagi of their males revealed that representatives of Hemiprotaetia Mikšič, 1963 currently recognised as valid genus in Cetoniini and representatives of Chalcoprotaetia Mikšič, 1963, currently recognised as a subgenus of Protaetia Burmeister, 1842 stay much closer than it was supposed. Also their distribution seems to be very similar, both are endemical to northern part of Philippines, mainly to Luzon Island. Intermediate species habitually imitating representatives of Chalcoprotaetia Mikšič, 1963, but in structure of male aedeagus very similar with Hemiprotaetia Mikšič, 1963 was collected in Luzon Island. It is here compared with currently known Hemiprotaetia Mikšič, 1963 and Chalcoprotaetia Mikšič, 1963 species and described as Protaetia (Chalcoprotaetia) sierramadrensis sp. nov. Based on study of several major characters in Hemiprotaetia Mikšič, 1963 and following concept of most of current researchers of Cetoniini, it is here proposed to threat this genus as a subgenus of Protaetia Burmeister, 1842. Protaetia (Hemiprotaetia) madjaasica sp. nov., cohabiting with Protaetia (Hemiprotaetia) boudanti (Arnaud, 1992) in Panay Island is compared with its congeners and described as new to science.

The generic distinctness of Mocuellus and Henschia (Cicadellidae) is proven. The genus Goniagnathus is divided into four genera: Goniagnathus (with the subgenera Goniagnathus s. str. and Goniozygotes), Epistagmastat. n. (with the subgenera Epistagma, Epitephra, and Episarca), Tropicognathusstat. n., and Telogonusgen. n. with the type species Goniagnathus pectinatus Fletcher, 2008. A new synonymy is established in the family Delphacidae: Leimonodite Kirkaldy, 1907 = Ferganodelphax Dubovsky, 1970, syn. n. The following replacement names are given for homonyms: in Delphacidae, Migma Emeljanov, nom. n. for Polytropa Emeljanov, 1982, nom. praeocc., non Polytropa Swainson, 1840 (Mollusca, Gastropoda: Muricidae); Dicranotropis vilbastei Emeljanov, nom. n., sp. propria for Dicranotropis montana Vilbaste, 1965, secondary homonym, non Dicranotropis montana (Horvath, 1897) = Stiroma montana Horvath, 1897; Dicranotropis vilbastei is restored as a distinct species; in Dictyopharidae, Ostopicus Emeljanov, nom. n. for Opsigonus Emeljanov, 2006, nom. praeocc., non Opsigonus Baudi de Selve, 1877 (Coleoptera, Melandryidae); Rugorana Emeljanov, nom. n. for Cnodalum Emeljanov, 1978, nom. praeocc., non Cnodalum Agassiz, 1846 (Coleoptera, Tenebrionidae); in Derbidae, Synavella Emeljanov, nom. n. for Synavea Emeljanov, 1995, nom. praeocc., non Synavea Lallmand, 1955 (Homoptera, Cercopidae). Several new combinations are formed in the family Cicadellidae. [ABSTRACT FROM AUTHOR]

Schusterolejeunea inundata (Spruce) Grolle is a widespread, yet poorly known species restricted to riparian habitats of the Amazon Basin in northern South America. Since its original description by Richard Spruce in 1884, phenotypic differences among populations convinced the original author to split the taxon into two varieties. An extensive review of Schusterolejeunea Grolle specimens hailing from disparate regions of the Amazon Basin has provided convincing evidence of discontinuities among leaf, lobule, and perianth morphology offering support for a novel taxonomic proposal. In the present review, the genus Schusterolejeunea encompasses two species, S. inundata and the newly elevated species Schusterolejeunea saxorum (Spruce) A.M.Sierra & C.E.Zartman, stat. nov., comb. nov., which differs from S. inundata by its oblong leaves, with large rectangular to oblong lobules, that cover 1/3-2/3 of the leaf lobe, and the perianth with five indistinct low keels. The variety Schusterolejeunea inundata var. fontinaloides (Spruce) A.M.Sierra & C.E.Zartman, comb. nov. is considered a distinct taxon, distinguished from S. inundata var. inundata by its ovate leaves, and lobules on the primary stem triangular with a longer keel extending 6-12 cells long. For each taxon, we present a detailed morphological description, current geographical distribution, and illustrations. [ABSTRACT FROM AUTHOR]

Despite the importance of morphological characters for classification, molecular data are now more widely used than morphology in phylogenetic reconstructions, particularly in studies of algae. The tribe Ceramieae C.Agardh ex Greville (Ceramiaceae) is a widespread, speciose, and morphologically diverse group of valuable red algae with many identified bioactives. We aimed to elucidate phylogenetic relationships in the tribe to delimit genera and provide a new classification. Generic delimitation is currently based on morphological characters, and there has been no overall reassessment of generic circumscriptions and evolutionary relationships using molecular data. We used three molecular markers (mitochondrial COI-5P, plastid rbcL and nuclear LSU). Within the Ceramieae, several clades are recovered, although the relationships among major clades are not supported. These clades are here recognized as genera, with new circumscriptions for Ceramium Roth, Carpoblepharis Kützing, Herpochondria F.Schmitz & Falkenberg, Campylaephora J.Agardh and Celeceras Kützing, and the proposal of Pseudoceramium Barros-Barreto & Maggs, gen. nov., Yoneshiguea Barros-Barreto, Maggs & M.A.Jaramillo, gen. nov. and Stirkia Barros-Barreto & Maggs, gen. nov. The Ceramieae show a high degree of morphological homoplasy among species as well as extreme phenotypic plasticity within species. Genera lack unique synapomorphies and multiple morphological characters are required to define most of them. Molecular data are critical for understanding systematics in this group.

Three new taxa are described: Pilemia (Pseudopilemia) arida sp. nov. from Jordan, P. (P.) hirsutula karadutensis ssp. nov. from Turkey, P. (P.) hirsutula richardi ssp. nov. from Iran (Lorestan), P. (P.) homoiesthes (Ganglbauer, 1888), stat. nov. upgraded to the species rank. P. (P.) hirsutula holosericea (Faldermann, 1837), stat. nov. is regarded as a valid name for a taxon from Transcaucasia and Turkey. [ABSTRACT FROM AUTHOR]

In 2019 and 2020, the population of Armada Staudinger, 1884 represented by specimens with light colouration of forewings (identical with this in Armada clio (Staudinger, 1884)) and with dark colouration (as in Armada barrygoateri Fibiger et Ronkay, 2003) was found in Stavropol Region of Russia. Study of genitalia of males and females with various colouration of forewings showed that all specimens belong to one species. Comparison of the females with the holotype of A. barrygoateri, described by a single female, and comparison of male genitalia with those of a topotype of A. clio showed the absence of clear differences between A. clio and A. barrygoateri, therefore the taxonomic rank of A. barrygoateri was changed to the subspecies, Armada clio barrygoateri stat. n., with the range limited by semideserts of Ciscaucasia.

New nomenclature and taxonomic changes are proposed for some taxa of the subgenus Callisthenes Fischer von Waldheim, 1820, genus Calosoma Weber, 1801. New synonymy is established: Calosoma panderi (Fischer von Waldheim, 1820) = C. karelini (Fischer von Waldheim, 1830), syn. n., = C. cyaneosterum Mandl, 1954, syn. n.;C. elegans rostislavi Semenov, 1906, stat. n. = C. elegans subtilestriatum Mandl, 1954, syn. n. The name C. breuningi Mandl, 1954 is proposed to replace the preoccupied name C. karelini (Fischer von Waldheim, 1846) (non Fischer von Waldheim, 1830). Calosoma elegans amethystinum (Obydov, 1997), stat. rest. is restored from a synonym of C. elegans semenovii (Motschulsky, 1860), the correct authorship and publishing date of this name are defined which had been initially proposed for infrasubspecific entity. Two new subspecies are described: C. breuningi iliensesubsp. n. from the plains and piedmonts on the right bank of the Ili River (Southeastern Kazakhstan) and C. elegans kashensesubsp. n. from the piedmonts on the left bank of the Kash River (Xinjiang-Uygur Autonomous Region of China).

All cavernicolous species of the millipede family Trichopolydesmidae from the Carpathian-Balkan arch and the Rhodope Mountains have been reviewed. At present the family has been shown to comprise five or six genera with eight or nine species. Two new genera have been described, viz., Balkanodesminus gen. nov., with two new species: B. dentatoides sp. nov. and B. serbicus sp. nov., from Bulgaria and Serbia, respectively, and the monospecific Rhodopodesmus gen. nov., with R. niveus sp. nov., from Bulgaria. Two new combinations and one new status have been proposed: Balkanodesminus bulgaricus (Strasser, 1962) comb. nov. ex Bacillidesmus bulgaricus Strasser, 1962 and Balkanodesminus dentatus (Strasser, 1966a) comb. nov., stat. nov. ex Bacillidesmus bulgaricus dentatus Strasser, 1966a. All genera and species are diagnosed with the inclusion of the most relevant remarks for each of them. Old museum types are checked for Bacillidesmus filiformis (Latzel, 1884) with lectotype designation, as well as for Trichopolydesmus eremitis Verhoeff, 1898. An identification key to all six genera and a distribution map for the eight species are provided, as well as brief remarks and general considerations on the family Trichopolydesmidae.

The Isturgia limbaria (Fabricius, 1775)/roraria (Fabricius, 1776) complex is analyzed, taking into consideration the external morphology of the adults (coloration and pattern of upperside and underside of wings), the morphology of the female genitalia (signum and lamella postvaginalis), of the tympanal organs and of the preimaginal stages, as well as molecular data. Based on the molecular data and morphology of signum and tympanic organs, the populations of this complex can be divided into two groups, one more western (with the taxa limbaria s. str. and delimbaria), distributed east to north-western Italy and part of Germany, and one more eastern (with the taxa roraria s. str., rablensis and anzascaria), distributed west to northern and eastern Piedmont (Italy) and north-eastern and south-eastern Germany. However, there are no consistent differences between the two groups in the diagnostic characters used until now to identify the two taxa (pattern of the wing upperside and underside). Although there is a considerable genetic distance between these two groups, the correlation between molecular differences and morphological characters (size of the signum and presence ̶ or absence ̶ of a roundish lobe in the bullae tympani) is not completely constant and the two groups of populations are not completely separated from each other: some populations of the northern Apennines (taxon delimbaria) cannot be clearly attributed to one or the other group. In the absence of constant morphological characters associated with the molecular differences and in the presence of Italian populations with intermediate characters, we suggest that the different taxa of this complex be considered as subspecies of the same species, as already proposed by Povolný and Moucha (1957, 1959). However, the data available do not allow definitive clarification of the taxonomic problem and further research is necessary.

The genus Stictane Hampson (1900) is reported for the first time in Korea, for the species Stictane chinesica (Draudt, 1931). Genitalia of Korean Agrisius fuliginosus Moore, 1872 is reexamined and was identified to Agrisius japonicas Leech, 1889. Up to now, unknown female of S. chinesica is newly described herein. Diagnostic comparisons are made with Stictane rectilinea (Snellen, 1879) and Agrisius fuliginosus Moore, 1872. Illustrations of adult and genitalia are presented.

Taxonomical, geographical and nomenclatorial aspects of Merizomena Chaudoir, 1873 are discussed. The genus Merizomena is divided in to 2 subgenera Merizomena s.str. and Dichromenta subg. n. One new species is described: M. kabaki sp. n. (Tajikistan). M. schoenmanni (Kirschenhofer, 1994) is restored as a valid species. Five new synonyms are established: M. silvatica Mikhailov, 1977 syn. n. = M. tricolor (Gebler, 1845); M. klapperichi (JedliËka, 1956) syn. n. = M. grandinella (Semenov, 1889); M. afgana (JedliËka, 1956) syn. n. = M. grandinella; M. buettikeri (Mateu, 1986) syn. n. = M. castanea (Klug, 1832); M. yemenita (Mateu, 1986) syn. n. = M. castanea. A lectotype is designated for M. castanea (Klug, 1832). Distribution maps are added. An identification key is provided. [ABSTRACT FROM AUTHOR]

The subgenus Rhoicosphenula Lange-Bert. has a unique character combination that differentiates it from Gomphosphenia subgen. Gomphosphenia Lange-Bert. In particular, Rhoicosphenula has striae/areola features that are similar to Gomphosphenia, but is differentiated from that genus by also having pseudosepta present on both poles of the valves, copulae with septa at one of the poles, and frustules almost rectangular in girdle view. Together, this character combination strongly supports it as an independent genus following modern diatom-taxonomy criteria. Moreover, the only species of Rhoicosphenula known so far was collected from a peculiar acidic and dystrophic habitat, whilst most Gomphosphenia s.s. species colonize medium-conductivity, alkaline inland waters. On the basis of LM and SEM studies, we also propose a species of Gomphosphenia (G. patrickiana Cantonati, Lange-Bert., Kociolek & A.A.Saber, sp. nov.) as new to science. The new species is mainly defined by its valve outline and dimensions, length to breadth ratio, striation density, and geographical distribution. It was found in several samples of two streams in Puerto Rico, sometimes with high relative abundance. Gomphosphenia patrickiana Cantonati, Lange-Bert., Kociolek & A.A.Saber, sp. nov. was much more abundant in the stream with lower nutrient (in particular P) concentrations, and higher ecological integrity. The new species seems to prefer moderately alkaline freshwater habitats with medium-high conductivity and oligo- to mesotrophic conditions, with moderate tolerance to N enrichment. Also noteworthy is the occurrence of the new species in streams with above-average magnesium concentrations (due to the local geology). This Neotropical, warm-water species might be a potential indicator of global warming effects. [ABSTRACT FROM AUTHOR]

[Display omitted] • Trypherus obscurimembris Pic, 1933 stat. nov. is reinstated as a valid species. • T. plagiocephalus Brancucci, 1983 is supplementarily described. • A new species is discovered from China (Fujian), T. sinensis sp. nov. • A key to the Trypherus species in the world is updated. The genus Trypherus LeConte, 1851 has dozens of species distributed in East Asia, but a few known in the mainland of China. In the present study, a large series of Chinese Trypherus material available allows us to make a taxonomic study. As a result, T. nankineus var. obscurimembris Pic, 1933 is removed from synonym of T. nankineus Pic, 1913 and reinstated as a valid species, T. obscurimembris Pic, 1933 stat. nov. Meanwhile, T. plagiocephalus Brancucci, 1983 is supplementarily described and illustrated to better understand its variation in structures of the aedeagus. Additionally, a new species is discovered and described under the name of T. sinensis sp. nov. (China: Fujian). They are illustrated with habitus and genital segments of both sexes, aedeagus and internal genitalia of females. Besides, the generic diagnosis is resummarized and an identification key to all Trypherus species of the world is updated. [ABSTRACT FROM AUTHOR]

Similarly looking representatives of Miksicus Özdikmen & Turgut, 2009 and Miksicoprotaetia Legrand & Chew Kea Foo, 2010, subgenera of Protaetia Burmeister are studied. Study of approximately 400 specimens of Protaetia (Miksicus) acuminata Fabricius, 1775 revealed that populations flying across its large distributional areal are not conspecific. Distribution of this species is here corrected and two new species are described, Protaetia (Miksicus) oceanica sp. nov. from isolated Enggano Island (Indonesia) and Protaetia (Miksicus) austrosundana sp. nov. from Sumba and Sumbawa Islands in Lesser Sundas (Indonesia). Protaetia (Miksicus) acuminata baveanica Mikšič, 1965 and Protaetia (Miksicus) acuminata freudei Mikšič, 1962 are raised to species level. Lawangia Schenkling, 1921 is withdrawn from synonymy with Protaetia Burmeister, 1842 and it is here considered as a valid subgenus of Protaetia Burmeister, 1842. Protaetia (Miksicoprotaetia) Legrand & Chew Kea Foo, 2010 is synonymised with Protaetia (Lawangia) Schenkling, 1921. Protaetia (Miksicus) binghami Arrow, 1910 is transferred to Protaetia (Lawangia) Schenkling, 1921 and description of its male is given. New replacement name Protaetia (Miksicus) kaorusakaii nom. nov. is proposed for Protaetia (Miksicus) sakaii Jákl, 2011 due to homonymy. Five species of Miksicus Özdikmen & Turgut, 2009 and one species of Lawangia Schenkling, 1921 are pictured, including aedeagi of males and compared with their relatives. New distributional records for several species are given. [ABSTRACT FROM AUTHOR]

Frullania diversitexta Steph. currently occupies its own subgenus, subg. Diversitextae (Kamim.) S.Hatt., although its taxonomic placement is somewhat enigmatic. The habit of the species, as well as the position and shape of the lobules, are morphologically comparable to species in subg. Diastaloba Spruce and subg. Frullania Spruce, whereas its tuberculate perianth ornamentation is reminiscent of species in subg. Trachycolea Spruce. Here, molecular sequence data resolves F. diversitexta within subg. Trachycolea in a relationship with F. plana Sull. (sect. Planae R.M.Schust.). Frullania diversitexta and F. plana have a similar branching pattern, leaf lobe shape, leaf cell areolation, stylus, lobule position, underleaf shape and primary branch appendages that often have two saccate lobules. Differences in their lobule shape, sexuality, position of the gynoecia and perianth ornamentation, however, decidedly warrant the placement of F. diversitexta in its own section, sect. Diversitextae (Kamim.) J.J.Atwood, Vilnet & Mamontov, stat. nov. Lectotypes are designated for F. diversitexta and its three synonyms: F. abducens Steph., F. sendaica Steph. and F. tosana Horik. (replaced synonym of F. tenella Steph., hom. illeg.). Frullania ignatovii Sofronova, Mamontov & Potemkin, having obovoid, skull shaped lobules with an unusual bilabiate mouth, is also resolved within subg. Trachycolea, in a sister relationship with F. davurica Hampe and F. jackii Gottsche. [ABSTRACT FROM AUTHOR]

First addition to the Afrotropical Dolichopodoidae (Diptera) Catalogue (2018) includes new species, new synonyms published in 2018–2020 and a few missing species published earlier. Syntormoneura Curran, 1926 syn. nov. is newly synonymised with Telmaturgus Mik, 1874. Syntormon pallipes longistylus Grichanov, 2001 is raised to a species level, Syntormon longistylus Grichanov, 2001 (stat. nov.). The addition of one subfamily, one tribe and 38 species and exclusion of three species (Campsicnemus armatus, Condylostylus congensis, Orthoceratium lacustre) result in a new total of 810 dolichopodoid species and subspecies in the Afrotropical fauna.

ABSTRACT Two nomenclatural changes are proposed in the tribe Athysanini (Cicadellidae: Deltocephalinae). Chlorotettix sexvarus DeLong, 1959, is newly placed in the genus Cocrassana Blocker & Larsen and is a senior synonym of the type species of Cocrassana, C. riepmai Blocker & Larsen, 1991, syn. nov. A revised diagnosis and illustration of the species are provided.

Wasps of the genus Eustenogaster van der Vecht, 1969, with 17 species currently recognized, are distributed from the Indian subcontinent in the west to the Philippines, Sulawesi Island and Java Island in the east. Two new species of hover wasp genus Eustenogaster (E. multifolia sp. nov., E. sumatraensis sp. nov.) are described from specimens collected in Sumatra Island. The female of E. vietnamensis occurring in Vietnam are described for the first time. The lectotypes of Paravespa eva Bell, 1936 and Ischnogaster ornatifrons Cameron, 1902 are designated. The new taxonomic status is proposed for Stenogaster eximioides Dover and Rao, 1922 as a good (=valid) species of Eustenogaster. The synonymy of Ischnogaster ornatifrons Cameron, 1902 with Eustenogaster micans (de Saussure, 1852) has been confirmed. A revised key to species and a taxonomic and distributional checklist of all the species of Eustenogaster are provided. [ABSTRACT FROM AUTHOR]

Taxonomy of the genus Cordulegaster Leach in Brewster, 1815 in the Eastern part of the Western Palaearctic is poorly resolved. A two-step approach was applied: sequences of mitochondrial and nuclear DNA fragments were used to sort specimens; poorly known or new taxa with their phenotypic variation were described. The existence of two traditional groups (boltonii- and bidentata-group) was confirmed. Cordulegaster coronata Morton, 1916, however, belongs to a different group. Molecular-analysis supported three known and one new species (C. heros Theischinger, 1979, C. picta Selys, 1854, C. vanbrinkae Lohmann, 1993, and C. kalkmani sp. nov.) in the boltonii-group. In the bidentata-group, all specimens from West-Turkey belonged to C. insignis Schneider, 1845, all specimens further east to a complex of four closely related species, which we name charpentieri-complex (C. amasina Morton, 1916, stat. rev., C. mzymtae Bartenev, 1929 C. charpentieri (Kolenati, 1846), stat. rev. and C. cilicia sp. nov.). The following taxa: C. insignis nobilis Morton, 1916, syn. nov., C. nachitschevanica Skvortsov and Snegovaya, 2015, syn. nov. C. plagionyx Skvortsov and Snegovaya, 2015, syn. nov. and the Caucasian subspecies C. insignis lagodechica Bartenev, 1930, syn. nov., were synonymized with C. charpentieri. Finally, we provide a key for all Western Palaearctic Cordulegaster.

A critical and annotated catalogue of 309 types of Chrysididae belonging to 144 species, subspecies, and taxonomically available variations housed in the Natural History Museum Vienna is given. The neotypes of Chrysis austriaca Fabricius, 1804, Chrysis radians Harris, 1776, Chrysis socia Dahlbom, 1854, Holopyga gloriosa var. caucasica Mocsáry, 1889 and the lectotypes of the following fifteen taxa are designated: Chrysis albipennis Dahlbom, 1854, Chrysis araxana Mocsáry, 1893, Chrysis circassica Mocsáry, 1893, Chrysis kaeufeli Zimmermann, 1944, Chrysis kohli Mocsáry, 1889, Chrysis priesneri Zimmermann, 1959, Chrysis procera Zimmermann, 1954, Chrysis pyrocoelia Mocsáry, 1889, Chrysis succincta var. pannonica Hoffmann, 1935, Chrysis valenciana Hoffmann, 1935, Gonochrysis mochii Zimmermann, 1938, Cleptes mutilloides Ducke, 1902, Hedychridium adventicium Zimmermann, 1962, Hedychridium luteum Zimmermann, 1940, and Holopyga ignicollis Eversmann, 1858. Previous lectotype designations of Amisega mocsaryi Ducke, 1902, Chrysis callosa Mocsáry, 1889, Chrysis falsifica du Buysson, 1891, Chrysogona alfkeni Ducke, 1902, and Cleptes mutilloides Ducke, 1902 are considered as invalid. Six new synonymies are proposed: Chrysis germari ssp. aeneibasalis Linsenmaier, 1987 syn.n. of C. germari ssp. calviensis Kusdas, 1974; Chrysis persephone Semenov & Nikolskaya, 1954 syn.n. of Chrysis picticornis Mocsáry, 1887; C. succincta var. pannonica Hoffmann, 1935 syn.n. of C. frivaldszkyi Mocsáry, 1882; C. stanleyana Schletterer, 1891 syn.n. of C. senegalensis Mocsáry, 1887; Holopyga pulchella Mocsáry, 1893 syn.n. of Hedychridium jakowlewi Semenov, 1892; Holopyga ignicollis Eversmann, 1858 syn.n. of Holopyga chrysonota (Förster, 1853). Chrysis anthea Zimmermann, 1963 sp.rev., Chrysis picticornis Mocsáry, 1887 sp.rev., Chrysis sodalis Mocsáry, 1893 sp.rev., Chrysis separanda Mocsáry, 1889 sp.rev., Chrysis seyrigi Zimmermann, 1961 sp.rev., Chrysis valenciana Hoffmann, 1935 sp.rev. are restored from synonymy. Pictures of 78 types are presented. The case of Holopyga ovata var. h Dahlbom, 1854 (= Holopyga ignicollis) is discussed: the first author who used the name ignicollis as a valid name is Eversmann (1858), who is therefore the author of this taxon. The type of Holopyga chrysonota (Förster, 1853) was found in the Berlin museum and matches both the lectotype of Holopyga ignicollis and the interpretation of Holopyga ignicollis sensu Linsenmaier (1959). As a consequence, Holopyga ignicollis Eversmann, 1858 is synonymised with Holopyga chrysonota (Förster, 1853). The first available name for Holopyga chrysonota sensu Linsenmaier (1959) is Holopyga similis Mocsáry, 1889. [ABSTRACT FROM AUTHOR]

The genus Crematogaster is one of the most species-rich and widespread groups of ants. Despite their often- high local abundance and important ecological interactions, the taxonomy of the genus is fragmentary and in great need of modern revisionary studies. As a first step towards a revision for the Arabian fauna of Crematogaster, a review of all known species with synoptic species accounts is provided. Seventeen species are recognized and illustrated from the Arabian Peninsula, of which two new species are described: C. jacindae Sharaf & Hita Garcia, sp. nov. from the Dhofar Governorate, Oman, and C. gryllsi Sharaf & Hita Garcia, sp. nov. from the Kingdom of Saudi Arabia (KSA) based on the worker caste. Crematogaster jacindae sp. nov. is easily separated from the remainder of the Arabian Crematogaster fauna due to its complete lack of propodeal spines, slit-shaped propodeal spiracles, and its distinct bicoloration, whereas C. gryllsi sp. nov. is readily distinguished by its unlobed postpetiolar dorsum. Furthermore, new country records are presented: C. acaciae Forel for the KSA and Yemen, and C. delagoensis Forel and C. jehovae Forel for the KSA C. antaris for Qatar, whereas C. luctans Forel is excluded from the Arabian fauna. In addition, on the basis of morphological examination of original type material, C. affabilis Forel is proposed as junior synonym of C. chiarinii Mayr, and C. striaticeps is elevated to species rank stat. nov. Furthermore, a new identification key for the Arabian species is provided, as well as distribution maps for all species. [ABSTRACT FROM AUTHOR]

Three new species of Noteolethaeus Woodward et Slater, 1962 (Hemiptera: Heteroptera: Rhyparochromidae: Rhyparochrominae: Lethaeini) are described: N. pallens Zámbó et Kondorosy, sp. n., N. vasarhelyii Zámbó et Kondorosy, sp. n. and N. banari Zámbó et Kondorosy, sp. n. The new species are in transitional position between Noteolethaeus Woodward et Slater, 1962 and Sweetolethaeus Slater, 1972, rendering the genus-level differentiation of the above two genera impossible. However, because the type species of the two genera are rather dissimilar, Sweetolethaeus is retained as subgenus of Noteolethaeus (stat. n.). The following new combinations are accordingly proposed: Noteolethaeus (Sweetolethaeus) macchiaensis (Slater, 1972), comb. n. and Noteolethaeus (Sweetolethaeus) termiticolus (Slater, 1972), comb. n. Noteolethaeus leeui Woodward et Slater, 1962 is recorded for the first time from Tanzania. A key to the identification of the species of Noteolethaeus is provided. [ABSTRACT FROM AUTHOR]

Four new species of the genus Hermonassa from Pakistan (H. moorei sp. n., H. tathabaya sp. n. and H. ayubia sp. n.) and Nepal (H. kalamantra sp. n.) are described and compared with their relatives of the H. anthracina and H. dispila species groups. The specific status of Hermonassa shizukoae Sugi, 1995 is re-instated (stat. rev.). The species treatments are illustrated with 32 colour images and 24 genitalia figures. [ABSTRACT FROM AUTHOR]

Pheidole comprises approximately 1,000 extant species distributed worldwide, being particularly diverse in the New World. In addition to its high diversity and ecological prevalence, the genus is also characterized by the predominantly intraspecific dimorphism, with major and minor workers. Currently, five fossil species are known, all of which are represented only by minor workers. A new species, †Pheidole anticua sp. nov., is described from Dominican amber, based on a major worker. Additionally, the identity of the currently known fossil species in Pheidole is discussed and †P. cordata from Baltic amber is considered as incertae sedis, resulting in no Pheidole species currently recognized for Baltic amber.

Data on the collection of the genus Epepeotes Pascoe, 1866 deposited in the Natural History Museum, London are presented. A total of 23 species/subspecies, including type specimens of 18 names, of them 13 valid, are recorded. Epepeotesuncinatuslineatopunctatus Breuning, 1960 is restored to subspecies-level status. Lectotypes are designated for Epepeotesuncinatusuncinatus Gahan, 1888 and Epepeotesandamanicus Gahan, 1893. Epepeotesluscusluscus (Fabricius, 1787) is newly recorded in Cambodia and Singapore, and Epepeotesuncinatusuncinatus Gahan, 1888 is newly recorded in Bangladesh. Images of the type and other significant specimens are provided for 23 taxa, mainly for the first time., Competing Interests: The authors have declared that no competing interests exist., (Guanglin Xie, Maxwell V. L. Barclay, Wenkai Wang.)

Clubiona Latreille, 1804, with more than 500 named species, is one of the largest genera of Araneae. The genus has 15 synonyms, most of which are not listed in the World Spider Catalog (2018) and unknown to many arachnologists. The most comprehensive survey of Clubiona sensu lato by Wunderlich (2011) also lacked a few synonyms. In this paper all genus group names described in Clubiona are listed with their type species. Most of these names correspond to the species groups recognised in Clubiona sensu lato. We agree that Porrhoclubiona Lohmander, 1944 (= Clubiona genevensis-group) deserves a status of a separate genus and provide the diagnosis of this taxon. Three species of Porrhoclubiona that occur in Central Asia are surveyed, and two of them are described as new to science: P. laudata (O. Pickard-Cambridge, 1885), comb. n. (♂♀, Xinjiang, Tibet, China), P. bosmansi sp. n. (♂♀, Tajikistan), and P. moradmandi sp. n. (♂♀, Fars, Iran). It seems that all records of P. genevensis L. Koch, 1866 from China refer to P. laudata. The records of Clubiona vegeta Simon, 1918 from Tajikistan and Iran refer to P. bosmansi sp. n. and P. moradmandi sp. n., respectively. The following new combinations have been established: Porrhoclubiona decora (Blackwall, 1859), comb. n., P. diniensis (Simon, 1878), comb. n., P. leucaspis (Simon, 1932), comb. n., P. minor (Wunderlich, 1987), comb. n., P. pseudominor (Wunderlich, 1987), comb. n., P. pteronetoides (Deeleman-Reinhold, 2001), comb. n., P. vegeta (Simon, 1918), comb. n., P. viridula (Ono, 1989), comb. n., and P. wunderlichi (Mikhailov 1992), comb. n. (all ex. Clubiona). SEM study of the structure considered earlier as scopula in Clubiona and Porrhoclubiona reveals that it is represented by several lateral rows of movable macrosetae (spines) with a locking mechanism.

Abstract The Barsine punicea Moore, 1878 species-group is revised. Two new species, Barsine bachma Volynkin & Černý, sp. nov. (Central Vietnam and Hainan, China) and Barsine sirikitae Volynkin & Černý, sp. nov. (North Thailand), and two new subspecies, Barsine punicea kachina Volynkin & Černý, ssp. nov. (North Myanmar) and Barsine bachma bolovena Volynkin & Černý, ssp. nov. (South Laos) are described. Barsine punicea melanandra Černý, 2009 is upgraded to the species level: Barsine melanandra Černý, 2009, stat. nov. Miltochrista rothschildi Draudt, 1914 is synonymized with Barsine punicea and downgraded to the subspecies status: Barsine punicea rothschildi (Draudt, 1914), syn. & stat. nov. The lectotype for Miltochrista coccinea Rothschild, 1913 is designated. Adult, male and female genitalia are illustrated. Graphical abstract Unlabelled Image Highlights • Barsine punicea Moore, 1878 is a complex of species in fact. • Two new species and two subspecies are discovered in this group. • Barsine melanandra Černý, 2009, stat. nov. is upgraded to species level. • Miltochrista rothschildi Draudt, 1914 is synonymized with B. punicea and downgraded to a subspecies.

Trachusa pubescens (Morawitz, 1872) s. l. has a distribution extending from south-eastern Europe over Anatolia and the Caucasus to Iran and Turkmenistan, and was formerly regarded as a species with high intraspecific variation. By means of an examination of 208 specimens from all parts of the distribution area, covering structural features of the head (mandibles, clypeus), the apical terga and the genitalia, the colouration pattern as well as a morphometric analysis of 26 body measurements with multivariate statistical methods (Principal Component Analysis, Discriminant Analysis), it was possible to assign the material to five species of which two are new to science (Trachusa balcanica sp. n. and T. hakkariensis sp. n.). Two taxa which had previously been described as "variations" or subspecies are elevated to species rank: T. verhoeffi (Mavromoustakis, 1955), stat. n. and T. maxima (Friese, 1931), stat. n. Additionally, some populations can be distinguished by their colouration pattern or by subtle differences in size or body shape, but these features are apparently of no taxonomic significance at the species level. Trachusa balcanica sp. n. and T. verhoeffi have distribution areas which do not overlap with any of the other members of the species group and can thus be characterised as allospecies. By contrast, the distribution areas of the other three species, T. pubescens, T. maxima and T. hakkariensis sp. n., overlap to a certain extent and they co-exist at least to some degree in sympatry. While they have been found in the same region, they have so far never been found together at exactly the same location and it is suggested that species divergence occurred in parallel with ecological differentiation. Niche partitioning such as flower preferences is a mechanism which may be invoked to explain this. Some specimens with intermediate characters were found, particularly in contact zones, and it is thought that some hybridisation may occur. A partly melanistic individual of T. balcanica sp. n. was found, which is probably the first described melanistic individual in the tribe Anthidiini. [ABSTRACT FROM AUTHOR]
