We describe a new genus and species of polychaete worm (Polynoidae, Macellicephalinae) from a previously unsampled areaof the Southern Ocean, Pine Island Bay in the Amundsen Sea. Austropolaria n. gen. is differentiated from other genera in thesubfamily Macellicephalinae by a combination of morphological characters such as the number of pharyngeal papillae, bodysegments, elytra, and position of ventral cirrus. The type species of this genus, Austropolaria magnicirrata n. sp., is described based on morphological characters, supplemented by molecular data.

Claviplatysgen. n. and its type species C.henryisp. n. (Hemiptera: Heteroptera: Plataspidae: Plataspinae) are described from Kerala, India. The new genus is related to the Indomalayan genera Heterocrates Amyot & Serville, 1843, Cratoplatys Montandon, 1894, and Cronion Bergroth, 1891, but differs from them and all other plataspid genera by the peculiarly modified antenna. The morphological characters and systematic relationships of the above genera are discussed.

The cynipid inquilines genus Saphonecrus is known to be a polyphyletic group with distinct lineages. One lineage is associated with Synophrus in the Western Palaearctic on section Cerris oaks. Another involves the type species of Saphonecrus, S. connatus, and represents a distinct and probably early-diverging lineage with a Palaearctic distribution on white oaks. The third main lineage is predominantly Asian, and associated with Quercus subgenus Cyclobalanopsis and Quercus section Cerris and the oak-related Fagaceae including Lithocarpus. This third lineage shows large diversity, and includes the genus Ufo, the European lineage of S. undulatus and S. haimi, and the herein described new genus, Lithosaphonecrus Tang, Melika & Bozsó, known from Taiwan and China, with four new species: L. formosanus Melika & Tang, L. dakengi Tang & Pujade-Villar, L. huisuni Tang, Bozsó & Melika and L. yunnani Tang, Bozsó & Melika. All the four described species are associated only with Lithocarpus. Descriptions, diagnoses, biology, and host associations for the new genus and species are given, as well as a key to species and cynipid inquilines genera. All taxa are supported by morphological and molecular data.

A new genus of the primitively segmented trapdoor spiders, which is endemic to the north of China, is described, Luthela gen. nov., and the status of Sinothela Haupt, 2003 and Sinothela sinensis (Bishop & Crosby, 1932) is discussed and both are treated as nomina dubia. The new genus Luthela gen. nov. is erected based on morphology and molecular data of the type species Luthela yiyuan sp. nov. A taxonomic revision of the new genus is given. Three Sinothela species are transferred to the new genus, L. luotianensis comb. nov. and L. schensiensis comb. nov. are redescribed using our newly collected specimens, include L. heyangensis comb. nov. as a junior synonym of L. schensiensis comb. nov., and describe six new species based on both male and female morphological characters: L. badong sp. nov., L. dengfeng sp. nov., L. handan sp. nov., L. taian sp. nov., L. yiyuan sp. nov., and L. yuncheng sp. nov.

Abstract The freshwater fish genus Astyanax is one of the most diverse among the Characidae. The genus is defined by a combination of character states that are widely distributed in Characidae. In addition, the genus has the broadest geographical distribution in the family, being found in a great variety of environments of the Neotropical region. Although phylogenetic relationships were treated only partially, many authors agree that the genus is not monophyletic. In this contribution, we study the phylogenetic relationships of Astyanax in the context of the family Characidae, by combining morphological and molecular data. A total of 520 morphological characters, nine molecular markers and 608 taxa are analysed, of which 98 belong to Astyanax. According to our results, Astyanax is not monophyletic. We recovered species attributed to Astyanax in different subfamilies: Gymnocharacinae (including the type species), Stevardiinae and Tetragonopterinae. Among the species recovered in Gymnocharacinae, most (including the type species, the resurrected Psalidodon, and the new genus Andromakhe gen. nov.) were recovered in Gymnocharacini, while the remaining ones were recovered in Probolodini (transferred to Deuterodon or the new genus Makunaima gen. nov.).

The new genus Doesburgedessa is here proposed to include Edessa rugifera Stål, 1872 (type species) and four other species new to science: D. nigrolimbata sp. nov., D. armata sp. nov., D. elongatispina sp. nov., and D. linnei sp. nov. The new genus is characterized by a very unusual metasternal process with a single anterior projection that clearly derives from the bifurcated metasternal process found in Edessa. These species are restricted to the Amazon region; D. rugifera n. comb. is known from Brazil (Amazonas and Mato Grosso), D. nigrolimbata sp. nov. from Peru (Madre de Dios) and Bolivia (Santa Cruz), D. armata sp. nov. from Brazil (Pará and Mato Grosso), D. linnei sp. nov. from French Guiana (Cayenne and St Laurent du Maroni) and Guyana (East Berbice-Corentyne), and D. elongatispina sp. nov. from Brazil (Amazonas). The species were illustrated and photographed and the descriptions were made using external morphological characters, mostly from the metasternal process and the male and female genitalia.

Abstract Allophlebia is proposed as a new genus in Meruliaceae based on morphological characters and molecular data. The genus is typified by Peniophora ludoviciana and the new combination A. ludoviciana is proposed. The genus is so far monotypic. The type species is characterized by a resupinate basidioma, a monomitic hyphal system with clamp connections, two types of cystidia (leptocystidia and metuloids), clavate basidia, and hyaline, thin-walled and ellipsoid basidiospores. A phylogeny for Allophlebia and related taxa was inferred from ITS and nLSU rDNA sequences and new information about the geographic distribution of A. ludoviciana is provided.

A new, over 10 cm long, sub-Antarctic shrimp, Fresnerhynchus crozeti n. gen., n. sp. is described based on a unique specimen collected with long lines at 1889 m on the slope of a seamount northwest of the Crozet Islands. It is included in the previously monotypic family Lipkiidae Burukovsky, 2012 based on morphological and molecular data. However, the posterior pereiopods of Fresnerhynchus are reminiscent to those of the Rhynchocinetidae, especially by the short spinose dactyli, and by the absence of a sternal plate. The elusive nature of F. crozeti, which is a large and highly characteristic shrimp, is attributed to its putative habitat (hard bottom, steep deep sea slopes), which is difficult to sample with conventional gear, and the remote geographical location. A brief discussion on the biogeography of Antarctic and sub-Antarctic decapods is provided. A review of Antarctic and sub-Antarctic dendrobranchiate and caridean shrimps is appended.

Sinalliaria is described here as a new genus of the family Brassicaceae from eastern China, based on the morphological characters and molecular sequences. Sinalliaria differs from the related genus Orychophragmus in having basal leaves petiolate, simple or rarely with 1‒3 lateral lobes (not pinnatisect); cauline leaves petiolate, cordate at base (not sessile, auriculate or amplexicaul at base); petals obovate to narrowly obovate, claw inconspicuous (not broadly obovate, with a claw as along as sepal); siliques truncate (not long-beaked) at apex. The microscopic characters of seed testa also show significant differences between Sinalliaria and Orychophragmus. Phylogenetic evidence from DNA sequences of nuclear ribosomal ITS and plastid region trnL-trnF indicates that Sinalliaria is a distinct group related to Orychophragmus and Raphanus, but these three genera do not form a clade. The new genus Sinalliaria is endemic to eastern China and has only one species and one variety. The new combinations, S. limprichtiana (Pax) X. F. Jin, Y. Y. Zhou & H. W. Zhang and S. limprichtiana var. grandifolia (Z. X. An) X. F. Jin, Y. Y. Zhou & H. W. Zhang are proposed here.
