Two new species of the Chilean endemic genus Neogonyleptes Roewer, 1913 are described based on specimens obtained in the Nahuelbuta mountain range, Biobío and La Araucanía Regions. The new taxa are morphologically allied to Neogonyleptes karschii (Sørensen, 1902); however, both differ from all species of the genus by their dorsal scutum area III+IV, which is armed with a large, apically bifurcate apophysis. Neogonyleptes floresi sp. nov. differs from N. pedrazai sp. nov. principally in the slender body and legs, the proximal constriction of the scutal apophysis, and the distally straight prolateral apophysis on coxa IV. Detailed descriptions, illustrations, and comparisons of the new species are given. Additionally, some comments are provided about the taxonomy of Neogonyleptes and allied genera.

[1] The first cosmetid (ornatus) There were already 54 species of harvestmen described in the world, when William Kirby (1819) described the first three Laniatores Thorell, 1876 (two from Brazil, one from Uruguay), placing them in the new genus Gonyleptes Kirby, 1819. In the very next paper in the taxonomic story of Opiliones Sundevall, 1833, Thomas Say (1821) described the first laniator from the USA, Gonyleptes ornatum Say, 1821. This was also the first species described of what we now know as Cosmetidae. Say was, therefore, the first to conceive what would later become the Laniatores (as we consider today), by recognizing the intimate relationship between what are now gonyleptids and cosmetids. Soon later, other researchers (Perty 1833; Hope 1836) proposed a different hypothesis (today refuted), by joining the cosmetids with what are now the Eupnoi Hansen & Sørensen, 1904. Say described the new species Gonyleptes ornatum Say, 1821 (incidentally getting the grammatical inflection incorrectly, in what should have been ornatus, masculine instead of neuter gender) from Cumberland Island, Georgia and East Florida. Say’s description is detailed and accurate enough to allow this species to be recognized without mistake (Fig. 2a). The name ‘ornatus’ (‘decorated’), as applied to a cosmetid, is adequate enough, but it has exceedingly low discriminatory value, and indeed, it was later used to name several unrelated species. This species was first combined with Cosmetus Perty, 1833 only 50 years later by Butler (1873)., Published as part of Kury, Adriano B. & Medrano, Miguel, 2023, Once upon a time in America: recognition of the species of Libitioides from USA, with comments on other American Cosmetidae (Opiliones, Laniatores), pp. 101-141 in European Journal of Taxonomy 875 (1) on page 104, DOI: 10.5852/ejt.2023.875.2143, http://zenodo.org/record/8064424, {"references":["Kirby W. 1819.

The genus Lacronia Strand, 1942 is herein revised, and a maximum parsimony phylogenetic analysis of morphological characters (30 taxa, 115 characters, 2962 scorings) is performed to test its monophyly. As a result, Lacronia is herein made monophyletic by means of the inclusion of Discocyrtus boraceae B. Soares, 1942, Discocyrtus niger Mello-Leitão, 1923 and Discocyrtus tenuis Roewer, 1917. Lacronia including those species is the sister group of Discocyrtus s. str. inside the DRMN-clade, and should be removed from Pachylinae Sørensen, 1884, although without a new subfamilial assignment for now. Four new junior subjective synonyms are detected for the first time (Discocyrtus rarus B. Soares, 1944 = Discocyrtus fazi Piza, 1942 = Discocyrtus niger Mello-Leitão, 1923; Discocyrtus infelix Mello-Leitão, 1940 = Discocyrtus nigrolineatus Mello-Leitão, 1923 = Discocyrtus tenuis Roewer, 1917). Accordingly, the following new combinations are proposed: Lacronia boraceae (B. Soares, 1942) comb. nov., Lacronia nigra (Mello-Leitão, 1923) comb. nov. and Lacronia tenuis (B. Soares, 1942) comb. nov. Lacronia is endemic to the Atlantic province of Brazil, with verified records from the states of Rio de Janeiro, Santa Catarina and São Paulo. As a geographic note, the record of ‘D. fazi’ for Chile is here discussed and considered incorrect.

It was not found intraspecific variation among the major morph males or among females. Historical taxonomic remarks Discocyrtus tenuis (treated here as Lacronia tenuis comb. nov.) is known only from its female holotype (SMF RI 1316). Discocyrtus nigrolineatus was described based on the female holotype (MNRJ 42428ꜝ), which was incorrectly reported as a male by Mello-Leitão (1935b: 29). His mistake could have been caused by the well-developed armature of the specimen’s leg IV, a common pattern in males of Pachylinae. Both holotypes (Lacronia tenuis comb. nov. and D. nigrolineatus) have been studied for this project and they were considered to be morphologically identical, especially based on the unique diagnostic leg IV armature. The type localities of L. tenuis comb. nov. (Santos, São Paulo) and D. nigrolineatus (Angra dos Reis, Rio de Janeiro) are congruent within the geographic range of the other records of that morphotype. Therefore, D. nigrolineatus is herein considered a junior subjective synonym of L. tenuis comb. nov. Discocyrtus infelix was described based on the male holotype (MNRJ 181ꜝ) with an illustration of its dorsal habitus (Mello-Leitão 1940: 9). It matches all major form males of L. tenuis comb. nov. studied here (we only used males coupled with females in the same vial previously identified as “ D. nigrolineatus ”). The type locality of D. infelix (Mangaratiba, Rio de Janeiro) is situated in the center of the geographic distribution of L. tenuis comb. nov. Hence, D. infelix is considered here a junior subjective synonym of L. tenuis comb. nov. Records BRAZIL, state of São Paulo: Juquiá (H. Soares 1966).

Fe IV thinner than in male, with armature reduced to a prominent spine on the distal third and a pair of dorso-distal spurs (retro-dorsal largest). Mt IV dorsally covered by ordinary tubercles. Intraspecific variation In the minor morph males (compared to major morph): DS narrower; Cx IV with reduced prolateral and retro-lateral apophyses; Fe IV is thinner, with reduced armature size. It was not found intraspecific variation among the major morph males or among females. Historical taxonomic remarks The female holotype of Discocyrtus niger (recognized here as Lacronia nigra comb. nov.), recorded as specimen MZSP 502, was not found during this study. However, its morphology (after reviewing the original description and illustration, especially referring to the large retro-lateral distal apophysis on Tr IV) is identical to the females of Discocyrtus rarus. The type locality of L. nigra comb. nov. (Pinheiral, Piraí, Rio de Janeiro) is congruent with the current geographical occurrences of D. rarus (Fig. 14), especially because there is a record by Soares & Soares from Seropédica, which is quite close to Piraí (40 km in a straight line). Therefore, D. rarus is considered here a subjective junior synonym of L. nigra comb. nov. Discocyrtus fazi was described by Piza (1942) based on the female holotype (MZUSP 1549ꜝ), in a paper focused on Chile’s diversity of Opiliones. The type locality of D. fazi was reported as Chile (Fig. 14), without any additional data. There are no other recorded specimens of D. fazi, either nominal or of something that could be interpreted as this species, since its description, in spite of several authors reviewing the Chilean opilionofauna (e.g., Pérez-Schultheiss 2021). The holotype of D. fazi is a perfect match to all the females assigned here as L. nigra comb. nov. This unlikely record could be a result of a mislabeling by Piza, who mostly worked with the material of Opiliones from São Paulo throughout his career. According to this scenario, 1) D. fazi is herein considered a junior subjective synonym of L. nigra comb. nov., and 2) its record from Chile is considered incorrect. Therefore, this revision of Lacronia unveils a previously undetected monophyletic group in one hand, helping to depurate the polyphyletic Pachylinae, while on the other hand allowing for a gradually clearer concept of Discocyrtus, both morpho- and geographically.

Genus Lacronia Strand, 1942 Luederwaldtia Mello-Leitão, 1923a: 518 [junior homonym of Luederwaldtia Schmidt, 1922 (Hemiptera)] [type species: Luederwaldtia serripes Mello-Leitão, 1923, by original designation]. Luederwaldtia originally in Pachylinae. Lacronia Strand, 1942: 397 [available replacement name for Luederwaldtia Mello-Leitão, 1923]. Luederwaldtia – Mello-Leitão 1926: 337; 1932: 166; 1935a: 99. — Roewer 1929: 218. — Kästner 1937: 389. — Soares & Soares 1954: 269. — H. Soares 1966: 286. — Muñoz-Cuevas 1973: 226. Lacronia – Kury 2003a: 174; 2003b: 29. — Kury & Orrico 2006: 148. Diagnosis Lacronia resembles Discocyrtus s. str. due to: 1) stylus straight on the glans (Fig. 11A–B); 2) apical portion of the stylus only as an undifferentiated extension of its stem (Fig. 3A–D); 3) ventral process of the glans with the same diameter of the stylus (Fig. 20A, D); 4) ocularium height (in lateral view) with thrice or more the eyes diameter length (Fig. 7B, E); 5) Fe II–III with a retro-dorsal distal spur (Fig. 3A); 6) Pa IV covered by acuminated tubercles on the dorsal view (Fig. 12G–H, J). Lacronia can be differentiated from Discocyrtus s. str. by: 1) mesotergum area III (on males) with a pair of paramedian spines (a pair of subconical structures in L. ceci) (Fig. 4B–G); 2) mesotergum area IV of the mesotergum not invading the posterior border of the dorsal scutum (area IV invading the posterior border of the dorsal scutum in L. boraceae comb. nov.) (Fig. 4A–D, F–G); 3) Ti III maceshaped (Fig. 12D); 4) Cx IV with acuminated tubercles on the prolateral border (Fig. 12A); 5) Cx IV with a prodorsal apophysis crenated on the posterior portion (Fig. 12A); 6) Cx IV with a prodorsal apophysis transversally inserted in relation to the main body axis (Fig. 7A); 7) Tr IV approximately quadrangular-shaped (Fig. 12G, I); 8) Fe IV approximately straight (in dorsal view) (Fig. 17F).

Penis (Figs. 3E–G): Ventral plate slightly hourglass-shaped, distal margin straight, lateral margins slightly convex subdistally, and concave at level of truncus-glans transition; a row of four distal C macrosetae, one D, short and blunt; basal group with two curved A macrosetae and one small B macroseta. Glans with sac moderately wide. Stylus elongated, slightly curved basally, then straight and directed distally, without discernible trichomes, with a pair of small apical teeth. Ventral process of glans approximately half the length of stylus, proximal half directed distally, then abruptly curved 90° distoventrally, ending in a sharp point. Variation. Pedipalp spination: alternative formulas observed are IiIi (tibia, prolateral) and iIiIiii (tarsus, retrolateral). Setiferous granules on the anterior margin of carapace can be reduced to only one each side (e.g., paratype male from Cayucupil). The frontal hump may bear an unusually prominent and triangular granule (e.g., paratype male of Peleco Chico). Distal apophyses of armature of area III+IV vary in the angle of divergence between 20° (paratype from Peleco Chico) and 40° (holotype). Tibia IV may have two closely contiguous ventral sub-distal major apophyses (e.g., paratype of Peleco Chico)., Published as part of Pérez-Schultheiss, Jorge, 2022, Two new species of Neogonyleptes Roewer, 1913 (Opiliones: Gonyleptidae: Pachylinae) from the Nahuelbuta mountain range, Chile, pp. 361-374 in Zootaxa 5168 (3) on pages 363-367, DOI: 10.11646/zootaxa.5168.3.7, http://zenodo.org/record/6882941, {"references":["Perez-Schultheiss, J., Urra, F. & Otarola, A.

The harvestmen family Gonyleptidae (Opiliones), the largest one in the Neotropics (Kury 2003), is astonishingly diverse in eastern South America. The species-rich genus Eusarcus Perty, 1833, is characteristic for this area. It is the second largest gonyleptid genus (Kury 2003; Hara & Pinto-da-Rocha 2010), with a long taxonomical history beginning in the 19th century, when Perty (1833) described the genus together with four species. The number of species increased gradually in the 20th century through the addition of new descriptions and the synonymies of several related genera, with the corresponding species transferals (Hara & Pinto-da-Rocha 2010). Eusarcus is a relatively well-studied taxon that has undergone a thorough systematic revision (Hara & Pinto-da-Rocha 2010). Currently the genus contains 40 valid species, some of them cave-dwellers, with 32 species inhabiting the Atlantic rainforest and Paraná semi-deciduous forests (Saraiva & DaSilva 2016; Santos Júnior et al. 2021). The remaining species are peripheral to the core geographic area and are found in the Brazilian Cerrado, in Paraguay, or in the “Pampas” grasslands of Argentina, Uruguay, and southern Brazil (Hara & Pinto-da-Rocha 2010).

Three new species of Eusarcus Perty, 1833 are described from Brazilian caves, increasing the number of species of the genus to 40, eight of which have occurrences in caves. Eusarcus capixaba sp. nov. is described from Lapa do Sítio Paraíso Cave, municipality of Ecoporanga, state of Espírito Santo. Eusarcus marmoreus sp. nov. is described from Caverna Archimides Panssini Cave, municipality of Vargem Alta, state of Espírito Santo. Finally, Eusarcus xambioa sp. nov. is described from Caverna da Explosão Cave, municipality of Xambioá, state of Tocantins. Notes on the species’ habitats and a distribution map are also provided.

Species of the genus Sadocus Sørensen, 1886 are conspicuous gonyleptids that occur in Chile and Argentina. Here, the genus is revised for the first time and the cladistic analysis based on morphological characters does not corroborate its monophyly unless a phylogenetically unrelated species is excluded (explained further on). A new classification is proposed for the seven species left in the genus and considered valid, of the 13 nominal species previously recognized. Two out of the seven valid species are considered as species inquirendae: Sadocus allermayeri (Mello-Leitão, 1945) [= Carampangue allermayeri Mello-Leitão, 1945] and Sadocus nigronotatus (Mello-Leitão, 1943) [= Carampangue nigronotatum Mello-Leitão, 1943]. The following synonymies are proposed: Sadocus bicornis (Gervais, 1849) [original combination = Gonyleptes bicornis Gervais, 1849] is a junior synonym of Sadocus asperatus (Gervais, 1847) [= Gonyleptes asperatus Gervais, 1847]; Sadocus conspicillatus Roewer, 1913, Sadocus exceptionalis (Mello-Leitão, 1946) [= Araucanoleptes exceptionalis Mello-Leitão, 1946] and Sadocus guttatus Sørensen, 1902 are junior synonyms of the valid name Sadocus polyacanthus (Gervais, 1847) [= Gonyleptes polyacanthus Gervais, 1847]; and Sadocus calcar (Roewer, 1913) [= Lycomedes calcar Roewer, 1913] is a junior synonym of the valid name Gonyleptes horridus Kirby, 1819. Sadocus brasiliensis Soares & Soares, 1949 is not congeneric with Argentinean/Chilean species of the genus according to the cladistic analysis and is here synonymized with Discocyrtus catharinensis (Mello-Leitão, 1923 [= Sadocus catharinensis Mello-Leitão, 1923]).

Gonyleptoidea, largely restricted to the Neotropics, constitutes the most diverse superfamily of Opiliones and includes the largest and flashiest representatives of this arachnid order. However, the relationships among its main lineages (families and subfamilies) and the timing of their origin are not sufficiently understood to explain how this tropical clade has been able to colonize the temperate zone. Here, we used transcriptomics and divergence time dating to investigate the phylogeny of Gonyleptoidea. Our results support the monophyly of Gonyleptoidea and all of its families with more than one species represented. Resolution within Gonyleptidae s.s. is achieved for many clades, but some subfamilies are not monophyletic (Gonyleptinae, Mitobatinae, and Pachylinae), requiring taxonomic revision. Our data show evidence for one colonization of today’s temperate zone early in the history of Gonyleptidae, during the Paleogene, at a time when the Neotropical area extended poleward into regions now considered temperate. This provides a possible mechanism for the colonization of the extratropics by a tropical group following the Paleocene–Eocene Thermal Maximum, explaining how latitudinal diversity gradients can be established. Taxonomic acts: Ampycidae Kury 2003 is newly ranked as family; Neosadocus Mello-Leitão is transferred to Progonyleptoidellinae (new subfamilial assignment). [Arachnids; biogeography; phylogenomics; transcriptomics.]

A morphological maximum parsimony analysis (2273 scorings; 25 taxa; 107 characters) is performed here with eight species of Discocyrtus Holmberg, 1878 to test their monophyly. According to the results obtained herein, only the four species Discocyrtus crenulatus Roewer, 1913, Discocyrtus flavigranulatus B. Soares, 1944 and Discocyrtus moraesianus Mello-Leitao, 1923 and Discocyrtus testudineus (Holmberg, 1876) (type species) belong to reduced core of Discocyrtus. The genus Pachylobos Piza, 1940 gen. reval. is herein revalidated from the synonymy of Discocyrtus and considered to consist of two species: Pachylobos littoralis comb. nov. (for Discocyrtus littoralis Mello-Leitao 1932) and Pachylobos longicornis comb. nov. (for Gonyleptes longicornis Mello-Leitao 1922). With that revalidation, the genus Discocyrtulusoma Piza, 1943 is retired from the Discocyrtus synonym list into the Pachylobos gen. reval. As other results, three new junior subjective synonyms are identified for the two species: Discocyrtus cornutus Piza, 1940 (senior synonym of Pachylobos areolatus Piza 1940 - its type species) = D. littoralis Mello-Leitao, 1932 and Discocyrtus guttatus Roewer, 1927 = Gonyleptes longicornis Mello-Leitao, 1922. A new genus is herein created, Senu gen. nov., to include two species: Senu leonardosi comb. nov. (for Discocyrtus leonardosi Mello-Leitao 1935 - here selected as type species) and Senu vestita comb. nov. (for Discocyrtus vestitus Mello-Leitao 1922). Another new synonymy is proposed here: Discocyrtus goodnighti Soares and Soares, 1945 = D. leonardosi Mello-Leitao, 1935. The members of these two genera are united with Neopachylus Roewer, 1913 in Neopachylinae subfam. nov. proposed here, and accordingly transferred from Pachylinae Sorensen, 1884 to there.

GEOGRAPHICAL REMARKS The male holotype of Paradiscocyrtus cerayanus (SMF RII 996/53) was originally reported as from the locality “ Brasilien (Ceraya)” by Roewer (1929: 248). As noted by Roewer (1931: 104), Mello-Leitão explained to him in a personal correspondence that Ceraya was a misspelling of the locality name and extrapolated this as being the state of “ Ceará ” in northeastern Brazil. Roewer added that all his records contained the misspelling and accepted without question Mello-Leitão’s interpretation. Subsequent authors did not pursue this question and later cataloguers – Soares & Soares (1954: 286) and Kury (2003: 185) – simply repeated “ Ceará ”. However, comparing that locality with the geographical data gathered and studied here, one cannot make sense of such an interpretation because the northeastern Brazilian fauna is quite different from the one in the Southeast (e.g. Kury 2003). Diacritics are often a source of confusion in toponyms, as exemplified in the misinterpretation by Henriksen (1932: 420) of the names “ Boyacá ” and “Choachí” (Cundinamarca, Colombia) respectively as “Boydla” and “Choact” (Medrano et al. 2020). With the benefit of cumulative decades of study of Brazilian Gonyleptidae, for us it is easier to understand that a cedilla under a C could easily have been misspelled by European collectors as a “Y”. This toponym “Ceraya” does not appear in further harvestmen literature, however, in the same paper, Roewer (1929: 255) described another Gonyleptidae as from “Caraya”, which gives us the remaining piece of the puzzle. This way, by replacing only a single letter, Caraya (or its further distortion Ceraya) can be easily retrieved as “Caraça”, a small mountain range in Minas Gerais state, southeastern Brazil. Further material of D. cerayanus n. comb. studied by us corroborates this new interpretation, because the specimens hail from Caeté, Minas Gerais, which is extremely close to the Serra do Caraça (about 20 km in a straight line). Therefore, we herein rectify the incorrect interpretation of Mello-Leitão/ Roewer (1931) of “Ceraya” as “ Ceará ” to [Serra do] Caraça, state of Minas Gerais, Brazil, which should be the correct type-locality of the species., Published as part of Carvalho, Rafael N. & Kury, Adriano B., 2022, Review of Paradiscocyrtus Mello-Leitão, 1927 (Gonyleptidae, Opiliones), with the transfer of Paradiscocyrtus cerayanus Roewer, 1929 to Discocyrtus Holmberg, 1878 and a new interpretation of its type locality, pp. 209-225 in Zoosystema 44 (9) on pages 217-223, DOI: 10.5252/zoosystema2022v44a9, http://zenodo.org/record/6517718, {"references":["ROEWER C.

Acanthopachylus aculeatus (Kirby, 1819) and A. robustus (Holmberg, 1876) comb. nov. (Figs. 1–2). Excluded combinations. Acanthopachylus butleri (Thorell, 1877): Roewer 1913 (nowadays assigned to genus Pachyloidellus Müller, 1918: Acosta 1993); Acanthopachylus crassus (Roewer, 1943): Capocasale & Bruno Trezza 1964 (currently in Pachylus Koch, 1839a: Acosta 1993, 2021). Note on the genus spelling. In the original publication, Roewer (1913) consistently spelled the genus name as Acanthpachylus [NZ, 1: 22]; 10 years later he emended it by inserting a missing “o”, to get the current spelling Acanthopachylus. Although Roewer (1923) does not explain the reasons for the change, according to ICZN Art. 33.2.1. this action is clearly intentional (i.e., the original and the modified spellings are both cited by Roewer 1923), what constitutes primarily an unjustified emendation [cf. NZ, 1: 17]. Moreover, the original spelling Acanthpachylus cannot be interpreted as an inadvertent error, since this category is not met by the incorrect use of connecting vowels in forming a name (ICZN, Art. 32.5.1.). In any case, the emended spelling Acanthopachylus gained prevailing usage (cf. synonymy in Kury 2003), so it became by force of use a “justified emendation” (ICZN Art. 33.2.3.1.), i.e., with no separate authorship and date, rendering Acanthpachylus as the “incorrect original spelling”. Distribution. Acanthopachylus aculeatus auct. has been deemed to be one of the most widespread harvestmen in South America. It was cited from Cayenne in the French Guiana (presumed “ types ” of Gonyleptes acanthurus, according to Roewer 1923: 413) up to the Strait of Magellan, in the southernmost tip of the continent (Roewer 1929: 190, one female). Mello-Leitão (1939) argued that the species spreads over “toute l’Amérique du Sud, du coté atlantique”, an exaggerated assertion repeated by B. Soares & H. Soares (1954). Eisner et al. (2004), citing Capocasale & Bruno Trezza (1964), still claimed that the species extends from the Guianas to Argentina. The only well documented records of Acanthopachylus, however, come from southern Brazil (Rio Grande do Sul State), Uruguay and Argentina (Ringuelet 1959; Capocasale 1968; H. Soares & B. Soares 1986; Kury 2003). Despite this restriction, the genus distributes over an extensive range on grassland-type biomes (Pampas in Argentina, similar savanna environments in Uruguay and Brazil; Acosta 2002), along with some peripheral records in neighboring ecoregions (Fig. 3). Both species have marked synantropic habits., Published as part of Acosta, Luis E., 2021, The return of a forgotten harvestman: revalidation of Gonyleptes robustus Holmberg, 1876, as the second species of Acanthopachylus Roewer, 1913 (Arachnida, Opiliones, Gonyleptidae), pp. 428-438 in Zootaxa 5040 (3) on pages 428-438, DOI: 10.11646/zootaxa.5040.3.7, http://zenodo.org/record/5531538, {"references":["Roewer, C.

The Brazilian Atlantic Forest has long been considered a global biodiversity hotspot. In the last decade, the phylogeographic patterns of endemic taxa have been unraveling the biogeographic history of the biome. However, highly diverse invertebrate species have still been poorly studied. Sodreana harvestmen (Gonyleptidae) are distributed in most of the humid coastal forests in the southern portion of the Atlantic Forest, a region that has experienced complex topographic evolution and differing climatic conditions since the Early Cretaceous, which likely affected the geographic distribution and diversification of the group. In this study, we investigated the molecular phylogeny and phylogeography of Sodreana to clarify the species relationships and to make inferences about the historical biogeography of the southern Atlantic Forest. We applied coalescent-based phylogenetic analyses using one mitochondrial and three nuclear markers coupled with an ecological niche modeling approach to verify relationships among species, date the main divergence events in the genus, and make inferences concerning possible changes in the geographical distribution and population dynamics from the past. Our results supported the validity of most Sodreana species and suggested that Paleogene-Neogene geomorphologic processes such as the formation of rivers systems, uplift of mountain ranges and related environmental changes have profoundly affected the evolutionary history of Sodreana. The ecological niche models showed that the areas potentially occupied by the species were greatly reduced during Quaternary glacial periods but no recent lineage divergences or genetic bottlenecks were detected, suggesting that climatically stable micro-habitats could have helped maintain populations during drier periods. Our study highlights the importance of humidity-dependent and poor-dispersal taxa in understanding the effects of ancient geological and climate processes on the Atlantic Forest biota.

Pachylus gracilipes Canestrini 1888: 107, Pl. 9, figs. 4, 4a-d. Type not found, presumably one female holotype from Resistencia, Chaco (Argentina). urn:lsid:zoobank.org:act: E439AEC6-9BD6-431C-9A42-B8F39E4E6AC0. Syn. nov. Pucrolia gracilipes: Roewer 1913: 17 (Unsichere Art! = species uncertain); Ringuelet 1959: 373 (species inquirenda); Kury 2003: 188 (species inquirenda). The general habitus of Eusarcus minutus comb. nov. (Fig. 1A) resembles closely most species in the genus. The main shared features include the three well-developed paracheliceral frontal apophyses, the shape and curvature of the prolateral apophysis on coxa IV of males, the triangular, short, blunt prolateral apophysis on the male trochanter IV, and male femur IV with prolateral and retrolateral rows of apophyses and two distinct ventroapical ones (Hara & Pinto-da-Rocha 2010). Unlike most Eusarcus species, which typically bear a median conic apophysis on the scutal area III, E. minutus lacks any armature on the scutum, a feature shared with a few other species, like e.g. E. sergipanus Hara & Pinto-da-Rocha, 2010, E. gemignanii (Mello-Leit��o, 1931) and E. uruguayensis (Ringuelet, 1955). In addition, the ocular mound of E. minutus is armed by a single apophysis (Fig. 1A), instead of the paired armature most frequent in genus Eusarcus (Hara & Pinto-da-Rocha 2010). The referred character states were used by Ringuelet (1959) to separate Pucrolia from Eusarcus. The tarsal formula 5-6-6-6 of the nominal genus Pucrolia (of little help) is shared with E. gemignanii, E. grumani H. Soares, 1966 and E. uruguayensis. Finally, the male genitalia of Eusarcus minutus (Fig. 1B���C) consistently match the descriptions of those of most Eusarcus species (cf. Hara & Pinto-da-Rocha 2010). As for the largely questioned Pucrolia gracilipes, it is to be considered a junior synonym of E. minutus. The type material of the former is presumably lost (Guariento et al. 2018), but drawings and description given by Canestrini (1888: 107, Pl. 9, figs. 4, 4a-d) clearly show a female E. minutus. The type locality of P. gracilipes (Resistencia, Chaco province, Argentina) is placed in middle of the geographic range of E. minutus (cf. Ringuelet 1959)., Published as part of Acosta, Luis E. & Guerrero, Eli��n L., 2021, The missing Eusarcus: generic relocation of Pucrolia minuta, with synonymic notes (Opiliones: Laniatores: Gonyleptidae), pp. 587-590 in Zootaxa 4990 (3) on pages 588-589, DOI: 10.11646/zootaxa.4990.3.11, http://zenodo.org/record/5026901, {"references":["Sorensen, W.

Species name is the Latin adjective martialis (of or pertaining to Mars), referring to Latin prosoponym Martinus (from the Roman war god Mars), from where the surname Martens originated. Named after the eminent German arachnologist Jochen Martens, by occasion of his 80th birthday. Diagnosis. Distinguished from all other species among other things by the unique large conk-shaped median lobe (cML) on posterior margin of St II and a lateral halter-shaped protuberance (hLP). Differs from all other Spinopilar (except S. magistralis) by the presence of a well-developed mesal pars stridens on Pp Fe. Further differs from S. magistralis by the stout mesotergal armature. Description. Male (holotype). Measurements: CL = 0.76, CW = 1.11, AL = 1.15, AW = 1.79. Dorsum (Figs 4B, 15A, B, C). Dorsal scutum bell-shaped: abdominal scutum much wider than carapace with sides gently converging posteriorly and without posterior constriction.Carapace with well-marked crescent-shaped groove, entirely smooth; lateral ridges deep; preocular mound moderately high, with scaly tegument. Ocularium high, elliptical, situated in the middle of the carapace, armed with robust erect acuminate spiniform apophysis. Lateral margins of scutum with row of setiferous tubercles extending from ozopores to middle of area III. This row doubled in the posterior part. Mesotergum divided into 4 areas by deep and wide substraight grooves. Median armature of areas I– IV increasing in size backwards. Scutal areas I–II each armed with a pair of paramedian blunt tubercles placed very close to each other (0.05 mm), otherwise entirely smooth. Scutal area III with a pair of paramedian acuminate setiferous tubercles, larger and slightly more separated (0.08 mm) than those of area II. These 2 main tubercles make part of a transversal row containing much smaller tubercles, 3 to 4 on each side. Scutal area IV similar to III, except for much larger and more separated (0.17 mm) main tubercles (which already enter the category of spines). Free tergites I–III each with a transversal row of respectively 12, 10 and 8 acuminate tubercles, the ones in middle pair clearly more robust than the others. Anal operculum with 3 transversal rows of 4, 3 and 2 acuminate setiferous tubercles. Venter. All coxae densely covered by oval setiferous tubercles, a few of those also present between stigmata. Free sternites with scattered setiferous tubercles. Cx I to III arched, transversal to main body axis; Cx II curved around Cx I, as wide as Cx I, in situ much longer than Cx III. Cx II and III delimit a narrow sternum. Maxillary lobe of Cx II as a small triangle. Cx I movable. Cx II linked to Cx III by only one pair of large lateral tubercular bridges; Cx III linked to Cx IV by two pairs of large lateral tubercular bridges. Cx IV slanted, larger than all others combined. Stigmatic area roughly triangular, fused to sternite II, with lateral grooves highlighting the stigmata. Posterior margin of the complex stigmatic area + sternite II with large, roughly conk-shaped, median lobe. Stigmata small, entirely transversal and partially covered by a mesal lobe. Cx IV, Tr IV and stigmatic area complex forming a ventral complex of 3 overlaid apophyses as follows: (1) Cx IV has a clearly biramous apophysis, mesal branch conic, applied against stigmatic apophysis and ectal branch as a fasciolate hyaline truncated apophysis (FAp, sensu Kury 2014) applicable against Tr IV; (2) stigmatic area has a robust halter-shaped lateral protuberance (hLP); (3) Tr IV has a ventro-mesal apical very long (surpassing protuberance in 2) and extremely robust spatulate apophysis, with a secondary branch mid-length forming a FAp, extremely similar to corresponding FAp of Cx IV. Tr IV furthermore has a cluster of 4 meso-basal very thick setae (PTC). Chelicera/Pedipalp (Figs 17A–E). Basichelicerite with well-developed bulla, separated from peduncle by a narrow waist.

Spinopilar anomalis (Sørensen, 1932) Olynthus anomalis Sørensen in Henriksen 1932: 251. Spinopilar anomalis: Kury 2003: 204. Type material. BRAZIL: Rio de Janeiro: Holotype ♂ (NHM, destroyed), Rio de Janeiro, [Itaocara: Fazenda] Serra Vermelha [near 21°44’S 42°01’W]. Remarks. This species has been originally described based on a male specimen originally in NHM, but now lost. The information that can be extracted from Sørensen’s (in Henriksen 1932) Latin description leads to the following diagnosis, which allows the distinction of this species from all others in the genus. Even after repeated expeditions, no further material of this species has been collected, which is not surprising, given the extreme degree of endemism of those small litter-dwelling Grassatores and the merciless deterioration of natural environments in the lower Paraíba Valley. This species is left out of the key due to the various lacunae in its description, which would extremely impair the comparisons. Diagnosis (based on the description of Sørensen in Henriksen 1932). (1) “limbus anterior tubere medio praeditus, tubere oculifero paullo minore” = preocular mound elevated, a little smaller than ocularium. (2) “areae coriaceae, quarta et quinta et limbus posterior et segmenta dorsalia tria anteriora libera granis praedita” = scutal areas III to V and free tergites I to III with granules. (3) “Tuber oculiferum... grano parvo apicali praeditum” = ocularium with a small tubercle. (4) “Areae coriacea, quarta et quinta granis magnis praeditae, in ordines singulos vix dispositis.” = scutal areas III to IV armed with large tubercles, barely arranged in a single [transversal] row. (5) “Limbus posterior et segmenta dorsalia libera tria anteriora coriacea, ordine singulo granorum magnorum pradita; anale dorsale granis paucis dispersis.” = scutal area V and free tergites I to III each armed with a single row of large tubercles; anal operculum with few scattered granules. (6) “In mare segmentum ventrale primum carinis lateralibus ambabus, in angulos singulos obtusos productis, erga apicem processus trochanteris IV positos.” = stigmatic area provided with a pair of lateral keels projected in obtuse angles, applied against process of Tr IV. (7) “Coxae IV processulo exteriore apicali recto, conico, acuto, et tuberculo interiore brevi robusto compresso, cujus margo posterior marginatus.” = Cx IV with prodorsal apical spiniform apophysis and retrodorsal protuberance with posterior margin marginated. (8) “Trochanter IV processu robusto interiore, levissime procurvo obtuso, granis magnis anterioribus duobus praedito, quae tuberculum coxale et angulum carina abdominalis ambiunt.” = Tr IV with robust retrolateral blunt process, gently procurved, with two large anterior protuberances., Published as part of Kury, Adriano B. & Araujo, Débora C., 2021, On Spinopilar from Rio de Janeiro state with description of three new species (Opiliones, Laniatores, Cryptogeobiidae), pp. 148-181 in Zootaxa 4984 (1) on page 154, DOI: 10.11646/zootaxa.4984.1.14, http://zenodo.org/record/4926797, {"references":["Henriksen, K.

May be distinguished from all other Spinopilar by the male Ti IV shaped like a baguette (Figs 3A, D, F) and the ocularium low, with spine tilted backwards (Figs 5F–G). Differs from other species (except S. martialis and S. magistralis) by the fusiform Mt IV of male (Figs 3D–F). Complementary description. Male (MNRJ 2251, contrasted with female (MNRJ 2251). Measurements: CL = 0.66, CW = 0.99, AL = 1.03, AW = 1.58. Fe I = 0.89, Fe II = 1.43, Fe III = 1.22, Fe IV = 1.65. Dorsum (Figs 3A, C–D, 5A, F–G). Dorsal scutum roughly bell-shaped: abdominal scutum wider than carapace with sides almost parallel. Carapace with well-marked C-shaped groove, entirely smooth; lateral ridges deep; preocular mound very high, with scattered acuminate tubercles. Ocularium low, stadium-shaped, situated in the middle of the carapace, armed with erect acuminate spiniform apophysis tilted backwards. Lateral margins of scutum with 2 irregular rows of setiferous tubercles extending from area I to area V. Mesotergum divided into 4 areas by deep substraight grooves. Median armature of areas I–IV increasing in size backwards. Scutal areas I–IV each armed with a pair of paramedian blunt tubercles. Area V and free tergites I–III each with a transversal row of 10–20 subequal acuminate tubercles. Anal operculum with uniformly distributed rounded tubercles. Venter (Figs 5B, E, 6A–D). Coxae I–IV and stigmatic area densely covered by stout setiferous tubercles. Free sternites each with row of setiferous tubercles. Cx I to III arched, transversal to main body axis; Cx II curved around Cx I, almost as wide as coxae I and III, in situ much longer than Cx III. Cx II and III delimit a narrow sternum. Maxillary lobe of Cx II as a small triangle. Cx I movable. Cx II linked to Cx III by two pairs of unequal lateral tubercular bridges; Cx III linked to Cx IV by six pairs of large lateral tubercular bridges. Cx IV slanted, barely larger than all others combined. Stigmatic area roughly Y-shaped, only faintly separated from Cx IV, fused to sternite II, with lateral grooves highlighting the stigmata (Figs 5B, 6A). Posterior margin of complex stigmatic area + sternite II without median lobe. Stigmata small, entirely transversal and free (Fig. 6A). Cx IV, Tr IV and stigmatic area forming a ventral complex of 3 overlaid apophyses as follows: (1) Cx IV has a weakly biramous apophysis, mesal branch short rounded, applied against stigmatic apophysis and ectal branch as a fasciolate hyaline truncated apophysis (FAp, sensu Kury 2014) applicable against Tr IV (Figs 6B, D); (2) stigmatic area has a robust lateral spade-shaped protuberance truncated in the apex (Fig. 6B); (3) Tr IV (densely covered by scaly tubercles) has a ventro-mesal apical stout apophysis with truncate apex, widely surpassing stigmatic protuberance 2, and in mid-length with a secondary branch as a FAp, matching corresponding FAp of Cx IV (Fig. 6B). Tr IV furthermore has a cluster of 4 meso-basal very thick striated setae (primary trochanteral cluster, PTC, Figs 6B, C) and a secondary cluster (STC) of two such setae associated with FAp (Fig. 6B).

Genitalia. Distal part of truncus abruptly bent as a botuliform oblique malleus (so that original dorsal surface is now apical and original apical is now ventral) and an erect large lamina parva (LP) (Fig. 9A). Well-developed haematodocha (hyaline button of Kury 2014) present at dorsal transition zone between truncus and malleus (Figs 9A, C). Lamina parva prismatic, subrectangular (in ventral view) with rounded corners (Figs 9B, D). Nine pairs of macrosetae (MS) A to E arranged as follows: MS A1 stout, inserted on latero-apical surface of malleus, close to the base of LP (Figs 9C, G).
