The Chilean genus Nanophareus Roewer, 1929 is revised and three new species are described: N. araucanus sp. nov. (typelocality: Parque Nacional La Campana, Valparaíso, Chile); N. bipartitus sp. nov. (type locality: Parque Nacional La Cam-pana, Valparaíso, Chile); N. bosqenublado sp. nov. (type locality: Parque Nacional Fray Jorge, Coquimbo, Chile). Thetype species, N. palpalis Roewer, 1929, is redescribed and a lectotype is designated. A cladistic analysis was performedusing these three new species plus N. palpalis and 14 more laniatorid species, and a data matrix of 72 characters: Sevenfrom the ocularium, 22 from the dorsal scutum, one from the venter, one from the chelicera, eight from the pedipalp, 24from male legs, and nine from male genitalia. Two equally most parsimonious trees were found (L = 210; C.I. = 0.41; R.I.= 0.51). Nanophareus was recovered as nested within a paraphyletic subfamily Pachylinae. The genus Nanophareus wasfound to be monophyletic based on the following exclusive synapomorphies: An external row of enlarged tubercles in-serted among small ones on lateral margin of the dorsal scutum (innapplicable in N. bosqenublado); the ventro-basal mar-gin of pedipalpal tibia curved 90 degrees in lateral view; and retrolateral seta of the pedipalpal tibia with a socket apically bifid (socket and seta longer than pedipalpal tibia length).

The diagnostic characters of the new taxa are defined and figures of the male genitalia are depicted. The synonymy of Platyderus neapolitanus (Reiche, 1855) and Platyderus canaliculatus jannonei Binaghi, 1955 is confirmed. Platyderus dalmatinus is treated as doubtful for the fauna of Italy. A key of the five Italian species of Platyderus from the South Apennines is included.

As part of an ongoing revision and cladistic analysis of the “K92 clade” (Gonyleptidae), the Brazilian genus Progonyleptoidellus Piza, 1940 is revised and two new species from São Paulo State are described: P. bocaina sp. nov. and P. picinguaba sp. nov. A cladistic analysis of the genus was performed using these two new species plus the three previously described species of the genus [P. fuscopictus (B. Soares, 1942); P. orguensis (Soares & Soares, 1954); and P. striatus (Roewer, 1913)], and 25 more additional gonyleptoid outgroup species, most being representatives of the K92 clade. The data matrix is composed of 109 characters: three from the ocularium, 24 from the dorsal scutum, six from the free tergites, nine from the pedipalp, 41 from the legs and 26 from male genitalia. The genus Progonyleptoidellus was recovered as monophyletic only with the exclusion of P. orguensis and was supported on the basis of only one exclusive synapomorphy: presence of dry-marks on sulci of dorsal scutum. Based on the cladistic analysis, P. orguensis was reallocated in Deltaspidium Roewer, 1927, herein considered a senior synonym of Adhynastes Roewer, 1930, and two new combinations are proposed: Deltaspidium orguense (Soares & Soares, 1954) and Deltaspidium tenue (Roewer, 1930). Diagnoses are given for Progonyleptoidellus, the previously described species, (P. fuscopictus and P. striatus) and the two new species.

Subterranean Environment

From an ecological and evolutionary standpoint, troglobitic organisms are of special interest because they have evolved in, and are restricted to, the subterranean environment. Iandumoema Pinto-da-Rocha, 1997 stands out for being the only Brazilian harvestmen genus with more than one troglobitic species, with three species described from caves in Minas Gerais state. Traditionally, testing the monophyly of troglobitic groups is more challenging than testing groups that do not include troglobites. Many of their shared features might be the result of convergence or parallelism imposed by the cave environment, such as the absence of light, limited and infrequent availability of food resources and low population density, among others. In the case of Iandumoema, this becomes even more difficult because the genus is currently included in the species-rich and polyphyletic subfamily Pachylinae. This study tested the monophyly of this troglobitic genus and proposed the first phylogenetic hypothesis for Iandumoema based on cladistic analysis using morphological data. The analysis included all described species of Iandumoema and three new troglobitic species: I. cuca, sp. nov. (type locality: Itacarambi, Gruta da Água do João Ferreira); I. gollum, sp. nov. (type locality: Presidente Juscelino, Lapa D’Água); and I. stygia, sp. nov. (type locality: Montes Claros, Gruta do Cedro). The matrix comprises 79 characters and 28 terminal taxa: six species of Iandumoema; 14 of Pachylinae; six from other Gonyleptidae subfamilies; one species of Cosmetidae; and one of Metasarcidae. The cladistic analysis resulted in one parsimonious tree (339 steps, consistency index = 0.35, retention index = 0.56). Iandumoema is a monophyletic and well supported genus, nestled among Brazilian ‘Pachylinae’. Three new species are described and an identification key and ecological remarks for all six species of the genus Iandumoema is provided.

Three New Species

Three new species and one new record are added to the philopotamid fauna of India from the Indian Himalaya. The newly described species under the genus Chimarra Stephens include Chimarra butticulata sp.n. and C. gangotriensis sp.n. both from Uttarakhand and C. sangtami sp.n. from Nagaland. The record of C. nigra Kimmins (from Sikkim) constitutes the first record of that species from India, although it was previously known from Nepal. It is redescribed here from India as there are minor differences in the male genitalia from previously described species (in original paper of Kimmins only lateral view of the phallus was illustrated and in the redescribed species the ventral view of phallus is illustrated along with the lateral view). The four species belong to two different species groups and one species is unplaced in the species group. These species are distinguishable from each other as well as from the previously known allied species by consistent taxonomic features of the inferior appendages, tergite X, and the phallic apparatus of males.

Three New Species

Ceratophila new genus (Erotylidae: Pharaxonothinae) inhabiting male cones of the Mesoamerican cycad genus Ceratozamia Brongniart (Zamiaceae) is described for seven new species and compared to other genera of the Pharaxonothinae. Ceratophila differs from other genera of the Pharaxonothinae in many characters, most notable of which are: lateral pronotal carina thicker anteriorly in lateral view; head with supraocular and transverse occipital lines; elytra lacking a basal bead; and stridulatory files at base of head narrowly separated. Ceratophila has the male genitalia laterally compressed with a short median lobe and flagellum, similar to other Erotylidae. In comparison, the most superficially similar pharaxonothine genus Pharaxonotha Reitter has: lateral pronotal carina thin along entire length; head lacking supraocular lines, but with transverse occipital lines; elytra with distinct basal bead; stridulatory files at base of head widely separated; and unique male genitalia that are dorsoventrally flattened with a long median lobe and flagellum. Ceratophila contains two subgenera, which differ most notably in external characters and sexual dimorphism. Members of Ceratophila (Ceratophila), the nominal subgenus, have: more cylindrical bodies, pronotum evenly convex dorsally; the pronotum lacking basal longitudinal grooves on disc; metatibiae that are distinctly triangularly dilated toward apex; and no apparent external sexual dimorphism. In comparison, members of Ceratophila (Vovidesa) new subgenus have: dorsoventrally flattened bodies; the pronotum explanate (concave) along lateral margins; the pronotum with basal longitudinal grooves on disc; metatibiae weakly or not dilated toward apex; and with all tibiae in males showing strong sexual dimorphism. Four new species are described within the subgenus Ceratophila: C. (C.) chemnicki, C. (C.) gregoryi, C. (C.) picipennis, C. (C.) sanchezae; and three new species are described within the subgenus Vovidesa: C. (V.) chiapensis, C. (V.) mixeorum, C. (V.) vazquezi. Keys to genera, subgenera and species of known adults based on morphology are provided.

Three New Species

The Neotropical water scavenger beetle genus Chasmogenus Sharp, 1882 is a diverse lineage with 34 described species. Here, three new species from the southwestern margin of the Guiana Shield are described using an integrative approach combining adult morphology and molecular data: Chasmogenus clinatus sp. n. (Brazil: Amazonas, Venezuela: Amazonas), C. gironae sp. n. (Venezuela: Amazonas), and C. inpa sp. n. (Brazil: Amazonas). Examination of the male genitalia is essential for confident identifications and thus unassociated females may prove extremely difficult to identify. New distributional records in Brazil for C. acuminatus Smith & Short, 2020 are provided as well as habitus images of newly described species and an updated key to the species from Venezuela, Suriname, Guyana, French Guiana and northern Brazil.

Partial Revision

The genus Robinsonia Grote, 1866 is partially reviewed following a large DNA barcode campaign. In the Robinsonia praphoea Dognin, 1906 group three new species are described: R. simulans sp. n. from French Guiana, up to now confused with R. praphoea itself and then R. decaensi sp. n. and R. maranhensis sp. n. both from the lower Amazon. R. drechseli sp. n. is described from Paraguay and R. inexpectata sp. n., a species close to R. mera (Schaus, 1910) from Costa Rica, is described as new from Peru and Bolivia. Finally the full species status is confirmed for R. flavicorpus Dognin, 1910 which is found to be differentiable from R. marginata Rothschild, 1909. All types are figured along with the male genitalia for most and some female genitalia for all studied species.

A survey of copepods from intertidal zone of the Persian Gulf and the Gulf of Oman resulted in discovery of three new species belonging to the family Canuellidae Lang, 1944. This work contributes to the final aim to describe meiobenthic copepods from this region and is the first description of meiobenthic copepods from Iranian coastline. The new species belong to the genera Brianola Monard, 1926, Canuella, T. & A. Scott, 1893, and Scottolana Huys, 2009. Compared to other congeners, Brianola haliensis sp. nov. is unique in the armature of the first leg, number of segments and setation of the antennary endopod and exopod. Canuella persica sp. nov. is easily distinguishable from its congeners by the shape of furcal rami and male genitalia. Scottolana gomezi sp. nov. is assigned to the longipes-group by the presence of two and three post-genital somites in the female and male, respectively. It is closely related to S. geei (Mu & Huys, 2004) recorded from the Bohai Sea, China, but can be distinguished by its eight-segmented antennary exopod, mouthparts setation, and shape of the furcal rami.
