Six new species are described as males: P. (Pe.) botiense, P. (Pe.) botosaneanui, P. (Pe.) camposense, P. (Pe.) intuber, P. (Pe.) reei, and P. (Pe.) tissamaharense. One additional species is described as female imago. P. (Pe.) pseudotritum and P. (Pe.) utonaiprimum are synonyms of P. (Pe.) tigrinum, and P. (Pe.) takorageheum and P. (Pe.) famibeceum synonyms of P. (Pe.) furusecundum. Five species misidentified as Pentapedilum and one as Polypedilum s. str. have been transferred, four to Polypedilum s. str. [P. (P.) inaijeum Sasa, Kitami et Suzuki, P. (P.) iriodeeum Sasa et Suzuki, P. (P.) jokasecundum Sasa et Ogata, and P. (P.) parasordens Ree], one to Ainuyusurika [A. yakuabeum (Sasa et Suzuki)] and one to P. (Uresi- pedilum). P. (Pe.) pseudotritum and P. (Pe.) utonaiprimum are synonymized with P. (Pe.) tigrinum, and P. (Pe.) tokarageheum and P. (Pe.) famibeceum synonymized with P. (Pe.) furudosecundum. Subgeneric diagnoses are given for all stages and sexes of the subgenus Pentapedilum Kieffer. Keys are provided for all stages and sexes of all available material from all zoogeographical regions. The phylogenetic analysis, which included some species of Polypedilum s. str. and all available Pentapedilum indicate that Pentapedilum is likely monophyletic, while Polypedilum s. str. is polyphyletic. The subgenus Pentapedilum can be divided into three relatively distinct apical groups and the remaining species in a basal Hennigian comb when a parsimony analysis is done. The convexum group consists of one Afrotropical species, and five High, East and South Asian species with one of them also occurring in the Indo-Pacific. The sordens group consists of 13 species from Asia, the Indo-Pacific and Africa. The apparently paraphyletic uncinatum group consists of 9 species from the Holarctic and Oriental regions. The zoogeographical distribution does not support any vicariance patterns, but indicates that the present distribution is caused by dispersal. Diagnostic characters and keys to the males of Ainuyusurika Sasa et Shirasaki is given and Pentapedilum yakuabeum Sasa et Suzuki and Polypedilum (P.) yakucedeum Sasa et Suzuki assigned to the genus. The genus appears to be close to Phaenopsectra Kieffer and is known from Japan only.

A new genus of Neotropical Lycidae, Currhaeus gen. nov., is herein proposed as the second Eurrhacini genus lacking parameres in male genitalia. Seven new species are described: Currhaeus striatus sp. nov., C. nigroapicalis sp. nov., C. championi sp. nov., C. tabascensis sp. nov., C. ruschii sp. nov., C. polegattoi sp. nov., and C. paranaensis sp. nov. Illustrations of diagnostic characters and a key to species identification are presented. Parsimony and maximum likelihood analyses of morphological data demonstrated that Currhaeus gen. nov. belongs in the crown Eurrhacini. Implied weighting parsimony trees recovered Currhaeus as sister to Eurrhacus Waterhouse.

Eastern Caribbean

Populations of Eleutherodactylus on the island of Dominica, West Indies, differ from other Lesser Antillean members of the genus by their vocalizations, morphology, sexual size dimorphism, allozymes, and chromosomes. Thus, these populations comprise a new endemic species, closely related to E. johnstonei and E. martinicensis. The new species is most abundant in montane forest habitats at elevations of more than 500 m. Females commonly attain snout–vent lengths of more than 35 mm, making them the largest Lesser Antillean Eleutherodactylus. Frogs are brown during the day, but change color to dark orange when active at night. This species is the ninth Eastern Caribbean Eleutherodactylus species and the fifth single-island endemic. A phylogenetic analysis of external and internal morphological characteristics shows that Eastern Caribbean Eleutherodactylus are members of two distinct clades, one of South American origin, the other of Greater Antillean ancestry. We suggest that the present distribution of these species results from the dispersal of elements of the larger herpetofaunas from the Greater Antilles and South America, and that rapid divergence of the Eastern Caribbean Eleutherodactylus fauna may be continuing. The phylogenetic analysis also confirms that morphological characters of Eleutherodactylus species can be highly homoplastic.

A characteristic new species Meotipa sahyadri n. sp. with tall and white translucent abdomen in females is described in detail based on morphology of both sexes, based on specimens collected from the Western Ghats of Maharashtra, Gujarat and Goa. The new species has epigynal projection which is known only in Meotipa picturata Simon, 1895, but differs in shape (trifid vs. quadrangular respectively). Males have longest straight embolus exceeding conductor length. Observations of its natural history are provided. Meotipa picturata is newly recorded from Goa, which extends its north-westward distribution from the previously known records from ‘Kodei Kanal’, India (type locality), Ratchasima Province, Thailand and East Kalimantan, Indonesia. A new combination Meotipa andamanensis (Tikader, 1977) n. comb. (=Argyrodes andamanensis) is proposed based on the comparison of description and illustrations provided in the original paper to that of the characters of the type species M.picturata. 242 morphological characters studied in the previous literature and one additional character ‘epigynal projection’ were scored for Meotipa sahyadri n. sp. and Meotipa picturata. These species were obtained monophyletic, placed within Theridiinae as sister to Chrysso cf. nigriceps using parsimony analysis and Bayesian inference.

AbstractAn update of the delimitation of the genus Bruggmanniella based on phylogenetic analysis using morphological data is presented. We included the seven new species of Bruggmanniella described between 2019 and 2020, and discuss some aspects of the evolutionary changes among the closely related genera Bruggmanniella, Pseudasphondylia, and Illiciomyia. Bruggmanniella is confirmed here as a monophyletic Neotropical lineage, divergent from the Asian species. The phylogenetic reconstruction hypothesized here reinforces the pertinence of the genus Odontokeros to house all species occurring in the Oriental/Palearctic region under Bruggmanniella. The delimitation of Bruggmanniella, the geographical distribution, and niche occupation are discussed.

Phylogenetic analysis was used to evaluate evolutionary relationships within the Cambrian suborder Olenellina Walcott, 1890; special emphasis was placed on those taxa outside of the Olenelloidea. Fifty-seven exoskeletal characters were coded for 24 taxa within the Olenellina and two outgroups referable to the “fallotaspidoid” grade. The Olenelloidea, along with the genusGabriellusFritz, 1992, are the sister group of the Judomioidea Repina, 1979. The “Nevadioidea” Hupé, 1953 are a paraphyletic grade group. Four new genera are recognized,Plesionevadia, Cambroinyoella, Callavalonia, andSdzuyomia, and three new species are described,Nevadia fritzi, Cirquella nelsoni, andCambroinyoella wallacei. Phylogenetic parsimony analysis is also used to make predictions about the ancestral morphology of the Olenellina. This morphology most resembles the morphology found inPlesionevadiaandPseudojudomiaEgorova in Goryanskii and Egorova, 1964.

Two new species of leucosiid crabs of the genusUrnalanaGalil, 2005, are described from Taiwan.Urnalana erytheman. sp. is distinguished from the superficially similarU. angulata(Rathbun, 1911) in the shape of the apical process of the male first gonopod, which is beak-shaped and curved ventrally in the former, but sickle-shaped in the latter.Urnalana hirsutan. sp. differs from the superficially similarU. elatulaGalil, 2005 in its setose carapace and the shape of the apical process of the male first gonopod, which is club-like in the former, vs. dagger-shaped and curved in the latter. Two species are recorded for the first time from Taiwan:Raylilia uenoi(Takeda, 1995), and the recently describedCoralliocryptus caementaKomai & Ng, 2012. Three additional species,Arcania sagamiensisSakai, 1969,Urnalana purarensis(Ovaere, 1987) andOreotlos latus(Borradaile, 1903) are recorded for the second time. Diagnostic characters, colour photos and distributional information of these species are presented in this paper.

A New Species

The crinipelloid genera Crinipellis and Moniliophthora (Agaricales, Marasmiaceae) are characterized by basidiomes that produce long, dextrinoid, hair-like elements on the pileus surface. Historically, most species are believed to be saprotrophic or, rarely, parasitic on plant hosts. The primary morphological diagnostic characters that separate Crinipellis and Moniliophthora are pliant vs. stiff (Crinipellis) stipes and a tendency toward production of reddish pigments (ranging from violet to orange) in the basidiome in Moniliophthora. Additionally, most species of Moniliophthora appear to have a biotrophic habit, while those of Crinipellis are predominantly saprotrophic. Recently, several new neotropical collections prompted a morphological and phylogenetic analysis of this group. Herein, we propose a new species and two new combinations: Moniliophthora mayarumsp. nov., described from Belize, is characterized by its larger pileus and narrower basidiospores relative to other related species; Moniliophthora ticoicomb. nov. (= Crinipellis ticoi) is recollected and redescribed from biotrophic collections from northern Argentina; and M. brasiliensiscomb. nov. (= Crinipellis brasiliensis), a parasite of Heteropterys acutifolia. The addition of these three parasitic species into Moniliophthora support a hypothesis of a primarily biotrophic/parasitic habit within this genus.

Thyestetha Pascoe, an apterous genus of Papuan Cryptorhynchinae is revised. It contains two previously describedspecies, T. carbonaria Faust and T. nitida Pascoe, plus seven new species: T. discolor sp. n., T. emarginata sp. n.,T. glabra sp. n., T. lubrica sp. n., T. oblita sp. n., T. puncticollis sp. n., and T. splendens sp. n.. Lectotypes are designatedfor T. carbonaria, T. nitida, and Pantoxistus rubripennis Chevrolat which is a junior synonym of T. nitida (syn. n.). Thegenus and its species are described and the characters relevant for their identification are illustrated. A key to the speciesis provided. Phylogenetic analyses are performed, utilizing molecular and morphological approaches. A maximumlikelihood tree including 5 Thyestetha species and 2 outgroups is presented, based on 3 mitochondrial and 4 nuclearmarkers. A maximum parsimony analysis of 19 morphological characters includes all described species. Thyestetha ispresumably closely related to Telaugia Pascoe and Elichora Pascoe. The group is restricted to New Guinea and some smaller neighboring islands.

The species of the former antlion subtribe Periclystina (Neuroptera: Myrmeleontidae) are revised. Prior to this work Periclystina comprised 10 genera and 63 species endemic to Australia (62 spp.) and New Guinea (1 sp.). In this work two former genera are synonymized and four new genera are proposed (for a total of 12 valid genera), and six former species are synonymized and 16 new species are proposed (for a total of 73 valid species). A parsimony analysis utilizing 62 morphological characters is used to infer phylogenetic relationships among all 73 species, and suitable outgroups. Based on the results of the phylogenetic analysis, the tribal and/or generic assignments of 55 (75%) of former Periclystina species are modified here. Periclystina and its two largest genera—Austrogymnocnemia and Glenoleon—were all recovered as polyphyletic in their former circumscriptions. Ten species—placed here in six genera: Anomaloplectron, Csiroleon, Fissuleon gen. nov., Franzenia, Fusoleon and Latileon gen. nov.—clustered phylogenetically with Acanthoplectron and are transferred to the tribe Acanthoplectrini. The remaining 63 species—placed in six additional genera: Austrogymnocnemia, Glenoleon, Megagonoleon gen. nov., Minyleon gen. nov., Periclystus and Riekoleon—form a monophyletic Periclystus genus group and are transferred to the tribe Dendroleontini. All 73 species are (re)described and illustrated. New identification keys are provided for the tribes of Dendroleontinae, for the Australian genera of Acanthoplectrini and Dendroleontini, and for each of the non-monotypic genera treated. In addition, five new lectotypes are designated and 35 new combinations are created.

Foreyclupea loonensis, gen. et sp. nov., is described from the early–middle Albian Loon River Formation of the Northwest Territories, Canada. The only specimen of the new species was originally described as a part of an enigmatic taxon Erichalcis arcta in 1975, which was assigned to the Clupeomorpha. Since then, E. arcta has proven to be a composite taxon, made up of clupeomorph and non-clupeomorph specimens. The non-clupeomorph material was redescribed as a Euteleostei incertae sedis and retained the species name. Described herein is the fossil clupeomorph specimen originally assigned to Erichalcis arcta. As in other members of the superorder Clupeomorpha, the ventral margin of the body in the specimen is covered with spiny scutes, and the supratemporal commissural sensory canal passes through the parietals. Along with these diagnostic characters, the new taxon also shows primitive traits of the basal members of the group, including a medioparietal skull roof, unfused halves of the neural spines of the abdominal vertebrae, and no evidence of presence of the recessus lateralis. When included in a phylogenetic analysis of the Early Cretaceous clupeomorphs, the new species forms a clade with the Early Cretaceous clupeomorphs from Mexico and Brazil, Ranulfoichthys dorsonudum and Scutatuspinosus itapagipensis, respectively.
