Weintrauboa yele new species (Pimoidae) is described and illustrated based on specimens collected in China. The taxonomic status and distribution of Weintrauboa insularis (Saito, 1935) new combination and of W. chikunii (Oi, 1979) are discussed and the former species is illustrated based on specimens from the Sakhalin islands. Parsimony analysis of morphological characters provides support for the monophyly of Weintrauboa and for its sister group relationship to the genus Putaoa Hormiga and Tu, 2008. Some comments on the phylogenetic placement of the recently erected family “Sinopimoidae” are provided.

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.

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.

A new spider genus, Ternatus n. gen., is erected to accommodate two new erigonine species from China, Ternatus malleatusn. sp. and Ternatus siculus n. sp. Descriptions and illustrations of the new genus and new species are provided. To test the phy-logenetic placement within Linyphiidae, morphological data of the two new species were added to the matrices of two previousstudies addressing the higher level phylogeny of erigonine spiders. The results of the cladistic analyses support the monophyly of the new genus and its sister group relationship to the genus Gonatium Menge, 1868.

Abstract. A complete morphological description, as preservation permits, is provided for a new Late Jurassic fish species (Tharsis elleri) together with a revision and comparison of some morphological features of Tharsis dubius, one of the most common species from the Solnhofen limestone, southern Germany. An emended diagnosis of the genus Tharsis – now including two species – is presented. The new species is characterized by a combination of morphological characters, such as the presence of a complete sclerotic ring formed by two bones placed anterior and posterior to the eye, a moderately short lower jaw with quadrate-mandibular articulation below the anterior half of the orbit, caudal vertebrae with neural and haemal arches fused to their respective vertebral centrum, and parapophyses fused to their respective centrum. A phylogenetic analysis based on 198 characters and 43 taxa is performed. Following the phylogenetic hypothesis, the sister-group relationship Ascalaboidae plus more advanced teleosts stands above the node of Leptolepis coryphaenoides. Both nodes have strong support among teleosts. The results confirm the inclusion of Ascalabos, Ebertichthys and Tharsis as members of this extinct family. Tharsis elleri n. sp. (LSID urn:lsid:zoobank.org:act:6434E6F5-2DDD-48CF-A2B1-827495FE46E6, date: 13 December 2018) is so far restricted to one Upper Jurassic German locality – Wegscheid Quarry near Schernfeld, Eichstätt – whereas Tharsis dubius is known not only from Wegscheid Quarry, but also from different localities in the Upper Jurassic of Bavaria, Germany, and Cerin in France.

Two New Species

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.

Equal Weighting

The Cryptini Eknomia Santos et Aguiar gen. nov. is proposed, described, and cladistically compared with representativespecies of 40 outgroup genera from twelve cryptine subtribes. A total of 98 morphological characters were evaluated. Allanalyses, conducted in TNT under implied and equal weighting, clearly suggest that Eknomia is a monophyletic groupand can be treated as a distinct genus. Its likely sister group, however, varied among different analyses and could not beascertained. The relationships of the new genus are therefore unclear, and because of this it is not assigned to any of thecurrently recognized subtribes. Eknomia can be diagnosed mainly by the anterior transverse carina of propodeum entirelyabsent; propodeum more or less uniformly strigate; clypeus almost entirely flattened; ovipositor stout, with compressed,minutely serrate flange at apex of dorsal valve, subapically crossed by a subvertical line; first metasomal spiracle placedat tergite midlength or nearly so; and hind margin of metanotum with tooth-like projections. The species E. nigra Santoset Aguiar, sp. nov., E. rubra Santos et Aguiar, sp. nov. and E. propodeator Santos et Aguiar, sp. nov. are described and illustrated. The genus is recorded from Colombia to southern Brazil.

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.

Inti gen. nov. (Hymenoptera: Eulophidae: Entedoninae), is described from Costa Rica and the Dominican Republic, and includes one new species, I. levis sp. nov. The new genus is characterized by four autapomorphies, and the possession of an additional 14 synapomorphies. Inti is compared to the Australian genus Horismenoides Girault with which it shares the most apomorphies, indicating a possible sister-group relationship. The relationship of Inti to the tribe Euderomphalini and to other groups in the subfamily is discussed briefly.
