AbstractPatagonicolaPackernew genusis described for two species of xeromelissine bee (Hymenoptera: Colletidae) from Patagonian Argentina. One species,P. graveliPackernew speciesis described; the second species,P. aenigma(Packer)new combination, originally placed inChilicolaSpinola, 1851 subgenusChilioediscelisToro and Moldenke, 1979, is designated as the type species. The new genus is superficially most similar toXenochilicolaToro and Moldenke, 1979 but possesses none of the derived characteristics that were originally used to define that genus. Results of a phylogenetic analysis, based upon 114 morphological characters, are presented and suggest that the new genus is the sister clade to (GeodiscelisMichener and Rozen, 1999 +XeromelissaCockerell, 1926). An illustrated key is provided for the genera of Xeromelissinae and for the two species ofPatagonicola.

The spider genus Putaoa new genus (Araneae, Pimoidae) is described to place two species of pimoids from China, Putaoa huaping new species (the type species) and P. megacantha (Xu & Li, 2007) new combination. Parsimony analysis of morphological characters provides support for the monophyly of Putaoa and for its sister group relationship to the genus Weintrauboa Hormiga, 2003 and corroborates the monophyly of Pimoidae.

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.

Neochloroglyphica gen. nov. and its type species N. perbella sp. nov. are described from Yunnan, China. Morphological characters and molecular phylogenetic analysis, based on one mitochondrial and three nuclear genes, support the hypothesis that Neochloroglyphica is a member of the tribe Neohipparchini, and that it is a sister genus to Chloroglyphica. Morphological characters, including those of the genitalia, are figured and compared with related genera, especially Chloroglyphica, Neohipparchus and Chlororithra. Diagnoses for the genus and the species are provided and illustrations of external features and genitalia are presented.

The genera of the family Monomachidae are revised. Chasca Johnson & Musetti, new genus, is described, with two species:Chasca andina Musetti & Johnson, new species (type species, Chile) and C. gravis Musetti & Johnson, new species (Peru).The genus Tetraconus Szépligeti is treated as a junior synonym of Monomachus Klug (new synonymy), and its type species istransferred to Monomachus as M. mocsaryi (Szépligeti), new combination A phylogenetic analysis places Chasca and Mono-machus as sister-groups; within Monomachus, the three species of Australia and two species of New Guinea are basal, and the radiation of 21 species in tropical America and Valdivia is recovered as a monophyletic group.

The genus-level classification of New World Erythroneurini is revised based on results of a phylogenetic analysis of 100 morphological characters. The 704 known species are placed into 18 genera. Erasmoneura Young and Eratoneura Young, previously treated as subgenera of Erythroneura Fitch, and Erythridula Young, most recently treated as a subgenus of Arboridia Zachvatkin, are elevated to generic status. Three species previously included in Erasmoneura are placed in a new genus, Rossmoneura (type species, Erythroneura tecta McAtee). The concept of Erythroneura is thereby narrowed to include only those species previously included in the nominotypical subgenus. New World species previously included in Zygina Fieber are not closely related to the European type species of that genus and are therefore placed in new genera. Neozygina, n. gen., based on type species Erythroneura ceonothana Beamer, includes all species previously included in the “ceonothana group”, and Zyginama, n. gen., based on type species Erythroneura ritana Beamer, includes most species previously included in the “ritana group” of New World Zygina. Five additional new genera are described to include other previously described North American Erythroneurini: Hepzygina, n. gen., based on type species Erythroneura milleri Beamer and also including E. aprica McAtee; Mexigina, n. gen., based on type species Erythroneura oculata McAtee; Nelionidia, n. gen., based on type species N. pueblensis, n. sp., three additional new species, and Erythroneura amicis Ross; Neoimbecilla, n. gen., based on type species Erythroneura kiperi Beamer and one new species; and Illinigina, n. gen., based on type species Erythroneura illinoiensis Gillette. Five new genera, based on previously undescribed species, are also recognized: Aztegina, n. gen, based on A. punctinota, n. sp., from Mexico; Amazygina, n. gen., based on type species A. decaspina, n. sp., and three additional new species from Ecuador; Hamagina, n. gen., based on type species H. spinigera, n. sp., and two additional new species from Peru and Ecuador; Napogina, n. gen., based on type species N. recta, n. sp., and one additional new species from Ecuador; Perugina, n. gen., based on type species P. denticula, n. sp., from Peru; and Spinigina, n. gen., based on type species S. hirsuta, n. sp., and an additional new species from Peru. Phylogenetic analysis suggests that the New World Erythroneurini consist of three lineages resulting from separate invasions from the Old World.

Microphthalminae Hartmann-Schröder, 1971 was proposed in Hesionidae to include Microphthalmus and Hesionides; however, the affinities of these genera to other members of Hesionidae have been debated, and some authors have concluded they do not belong in Hesionidae. Herein, based on morphological characters, a phylogenetic analysis of the subfamily and some other similar poorly-known genera, with an uncertain position in Hesionidae was performed to clarify their affinities. Our results indicate that Microphthalminae, as currently delimited, is paraphyletic. The inclusion of Struwela, Uncopodarke, and Westheideius, a new genus, as well as the recognition of Fridericiella are proposed to meet the requirement of monophyly; and as result of this, the elevation in rank to the family level is herein presented. Furthermore, the type species for Hesionella and Struwela are redescribed, and a new species in the latter is described. A key to identify microphthalmid genera is also included.

Recent survey work for planthoppers at La Selva Biological Station in Costa Rica found two new species allied with Cenchrea Westwood. The cytochrome c oxidase subunit I (COI) and 18S were sequenced for the new taxa and used these data to assess the genus-level standing of the new taxa. The new taxa do not cluster with Cenchrea dorsalis Westwood, the type species of Cenchrea. A new genus Tico gen. n. described for the reception of new species described as Tico emmettcarri sp. n. (the type species) and Tico pseudosororius sp. n. Cenchrea sororia Fennah is moved to Tico gen. n., to form the new combination Tico sororius (Fennah). Tico gen. n. is compared with allied genera, and review genus-level diagnostic features and the species composition of Cenchrea, which appears to be compositionally heterogenous, but additional data is needed to evaluate genus-level placement of most species.

AbstractSystematic analysis shows that the Southern Hemisphere bivalve genus Retrotapes includes the Antarctic species R. antarcticus, R. newtoni, and R. robustus and recognizes for the first time the presence of Katelysia represented by K. florentinoi. Two new genera were erected in this study: Marciachlys new genus to include M. inflata new combination, and Adelfia new genus, which includes A. austrolissa new combination and A. omega new species from the Eocene of Antarctica, and the late Eocene Chilean A. arenosa new combination. Eurhomalea carlosi was synonymized with K. florentinoi; Cyclorismina marwicki with R. antarcticus; Gomphina iheringi was considered an indeterminate species; and Cockburnia lunulifera was excluded from the Tapetinae. These systematic assignments are supported by a phylogenetic analysis, which recognizes an Austral clade of Tapetinae, comprising all the genera mentioned above, along with Marcia, Paleomarcia, Atamarcia, and Protapes.UUID: http://zoobank.org/a8c91a9f-99ec-4235-8416-d398771a3eb2

The morphology of Putoniessa Kirkaldy is reviewed and the genus revised. In total, 28 species are recognised: the type species, P. dignissima Kirkaldy, which is removed from synonymy; one new combination, P. dorsalis (Walker); eight previously described species, P. nigra (Walker), P. minima Evans, P. mackei Evans, P. draba Evans, P. taradalensis Evans, P. sordida Evans, P. nigrella Evans and P. turneri Evans; and 18 new species, P. rieki, P, brisbanensis, P. hickmani, P, neboissi, P. stanthorpensis, P. woodwardi, P. striata, P. evansi, P. variegata, P. tasmaniensis, P. grossi, P. serrata, P. northamensis, P. bifurcata, P. kiataensis, P. watsoni, P. fusca and P. aroka. P. nota Evans is excluded from the genus, and P. maculata Evans is synonymised under P. dorsalis (Walker). P. rivularis (Walker), originally described under Bythoscopus Germar, and P. galliensis Evans are considered as species of uncertain identity. The genus is shown to have a disjunct Bassian distribution with some eastern species extending northwards into the south-east of the Tomesian province. A consensus cladogram for Putoniessa, based on morphological characters, is presented. Large areas of the cladogram remain unresolved because of high levels of homoplasy among the limited number of reliable ingroup characters available. The cladogram does not support a purely vicariant biogeographic hypothesis. Theories that receive qualified support involve an eastern origin for the group followed by either an east-to-west dispersal or a vicariance event affecting a single taxon subsequent to initial speciation. A western origin for the group is strongly refuted.

Unlike most terrestrial parasitengone mites (chiggers, erythraeids), known mostly from parasitic and easy-to-collect larvae, smaridid systematics are mainly based on the post larval instar. Larvae are rarely collected, and their biology and host associations are virtually unknown. Here we infer phylogenetic relationships of Smarididae based on 50 morphological characters using both larval and post larval instars, including data on the larval morphology of Trichosmaris obtained through rearing. The subfamily Smaridinae, as currently understood, was recovered paraphyletic: the genus Smaris was rendered as basal smaridid lineage, while the genus Fessonia (Smaridinae) was sister to Hirstiosomatinae, albeit with moderate support. Our analysis suggests that the genus Surasmaris Southcott, 1995 is a junior synonym of Trichosmaris Southcott, 1963 (syn. nov.), and two Sphaerotarsus species should be placed into Hirstiosoma: Hirstiosoma baenai (Mayoral & Barranco, 2017) comb. nov., Hirstiosoma quercus (Yazdanpanah, Saboori & Hakimitabar, 2016) comb. nov. Sphaerotarsus monticolus Southcott, 1997 and S. leptopilus were recovered as independent lineages, and hence, a new genus Southcottiana gen. nov. is proposed to include Southcottiana monticola comb. nov (Southcott, 1997). We describe two new species, Trichosmaris paulensis sp. nov. (adults, larvae) and T. calcarensis sp. nov. (larva), and present the first description of larval T. dispar, the type species of Trichosmaris, previously known only from post larval instars. Based on the above results, we give a key to larval genera of Smarididae and a key to species of Trichosmaris (larval and postlarval instars).
