External and genital characters of both male and female of this new subspecies are illustrated and described. Coladenia neomaeniata Fan & Wang, 2006, syn. n. is proposed to be a junior synonym of Coladenia maeniata Oberthür, 1896, and the distribution of this species is briefly discussed.     

Four new species of hangingflies (Insecta,Mecoptera, Bittacidae) from the Middle Jurassic of northeastern China

Two new species of Mongolbittacus Petrulevičius, Huang & Ren, 2007, Mongolbittacus speciosus sp. n. and Mongolbittacus oligophlebius sp. n., and two new species of Exilibittacus Yang, Ren & Shih, 2012, Exilibittacus foliaceus sp. n. and Exilibittacus plagioneurus sp. n., in the family Bittacidae, are described and illustrated based on five well-preserved fossil specimens. These specimens were collected from the late Middle Jurassic Jiulongshan Formation of Daohugou, Inner Mongolia, China. These new findings enhance our understanding of the morphological characters of early hangingflies and highlight the diversity of bittacids in the Mid Mesozoic ecosystems.     

Pseudofornicia gen. n. (Hymenoptera,Braconidae, Microgastrinae), a new Indo-Australian genus and one new species from Vietnam

Pseudofornicia gen. n. (Hymenoptera: Braconidae: Microgastrinae) is described (type species: Pseudofornicia nigrisoma sp. n. from Vietnam) including three Oriental (type species, Pseudofornicia flavoabdominis (He & Chen, 1994), comb. n. and Pseudofornicia vanachterbergi Long, (nom. n. for Fornicia achterbergi Long, 2007; not Fornicia achterbergi Yang & Chen, 2006) and one Australian species (Pseudofornicia commoni (Austin & Dangerfield, 1992), comb. n.). Keys to genera with similar metasomal carapace and to species of the new genus are provided. The new genus shares the curved inner middle tibial spur, the comparatively small head, the median carina of the first metasomal tergite and the metasomal carapace with Fornicia Brullé, 1846, but has the first tergite movably joined to the second tergite and the third tergite 1.1–1.6 × as long as the second tergite medially and is flattened in lateral view. One of the included species is a primary homonym and is renamed in this paper.

The new species is distinguishable from Nihonotrypaea petalura (Stimpson, 1860) by the proximolower margin of the carpus of the male major cheliped bearing several small denticles.     

Phylogenetic revision of Minyomerus Horn, 1876 sec. Jansen & Franz, 2015 (Coleoptera,Curculionidae) using taxonomic concept annotations and alignments

This contribution adopts the taxonomic concept annotation and alignment approach. Accordingly, and where indicated, previous and newly inferred meanings of taxonomic names are individuated according to one specific source. Articulations among these concepts and pairwise, logically consistent alignments of original and revisionary classifications are also provided, in addition to conventional nomenclatural provenance information. A phylogenetic revision of the broad-nosed weevil genera Minyomerus Horn, 1876 sec. O’Brien & Wibmer (1982), and Piscatopus Sleeper, 1960 sec. O’Brien & Wibmer (1982) (Curculionidae [non-focal]: Entiminae [non-focal]: Tanymecini [non-focal]) is presented. Prior to this study, Minyomerus sec. O’Brien & Wibmer (1982) contained seven species, whereas the monotypic Piscatopus sec. O’Brien & Wibmer (1982) was comprised solely of Piscatopus griseus Sleeper, 1960 sec. O’Brien & Wibmer (1982). We thoroughly redescribe these recognized species-level entities and furthermore describe ten species as new to science: Minyomerus bulbifrons sec. Jansen & Franz (2015) (henceforth: [JF2015]), sp. n., Minyomerus aeriballux [JF2015], sp. n., Minyomerus cracens [JF2015], sp. n., Minyomerus gravivultus [JF2015], sp. n., Minyomerus imberbus [JF2015], sp. n., Minyomerus reburrus [JF2015], sp. n., Minyomerus politus [JF2015], sp. n., Minyomerus puticulatus [JF2015], sp. n., Minyomerus rutellirostris [JF2015], sp. n., and Minyomerus trisetosus [JF2015], sp. n. A cladistic analysis using 46 morphological characters of 22 terminal taxa (5/17 outgroup/ingroup) yielded a single most-parsimonious cladogram (L = 82, CI = 65, RI = 82). The analysis strongly supports the monophyly of Minyomerus [JF2015] with eight unreversed synapomorphies, and places Piscatopus griseus sec. O’Brien & Wibmer (1982) within the genus as sister to Minyomerus rutellirostris [JF2015]. Accordingly, Piscatopus sec. Sleeper (1960), syn. n. is changed to junior synonymy of Minyomerus [JF2015], and its sole member Piscatopus griseus sec. Sleeper (1960) is moved to Minyomerus [JF2015] as Minyomerus griseus [JF2015], comb. n. In addition, the formerly designated type Minyomerus innocuus Horn, 1876 sec. Pierce (1913), syn. n. is changed to junior synonymy of Minyomerus microps (Say, 1831) [JF2015] which has priority. The genus is widespread throughout western North America, ranging from Canada to Mexico and Baja California. Apparent patterns of interspecific diversity of exterior and genitalic morphology, varying host plant ranges, overlapping and widely extending species distributions, suggest an early origin for Minyomerus [JF2015], with a diversification that likely followed the development of North American desert biomes. Three species in the genus – i.e., Minyomerus languidus Horn, 1876 [JF2015], Minyomerus microps [JF2015], and Minyomerus trisetosus [JF2015] – are putatively considered parthenogenetic.     

Four new species and additional records of Domene and Lathrobium from the Dayao Mountains,southern China

Material of the paederine genera Domene Fauvel, 1873 and Lathrobium Gravenhorst, 1802 from the Dayao Mountains, southern China, is examined. Eight species are identified, three of them described previously and five undescribed. Four species are described and illustrated for the first time: Domene hei Peng & Li, sp. n., Lathrobium jinxiuense Peng & Li, sp. n., Lathrobium kuan Peng & Li, sp. n. and Lathrobium leii Peng & Li, sp. n. One probably undescribed species of Lathrobium remains unnamed.     

Four new species of the genus Saigona Matsumura (Hemiptera,Fulgoromorpha, Dictyopharidae) from China

Four new species of the genus Saigona Matsumura, 1910, Saigona anisomorpha Zheng, Yang & Chen, sp. n., Saigona daozhenensis Zheng, Yang & Chen, sp. n., Saigona dicondylica Zheng, Yang & Chen, sp. n. and Saigona tenuisa Zheng, Yang & Chen, sp. n., from China, are described and illustrated. A key to the species of Saigona is provided.     

Two new species and one new record of Parakiefferiella Thienemann, 1936 from China (Diptera,Chironomidae)

Two new species of the genus Parakiefferiella Thienemann, 1936 (Parakiefferiella fasciata Liu & Wang, sp. n. and Parakiefferiella liupanensis Liu & Wang, sp. n.) are described as adult males from China. Parakiefferiella tamatriangulata Sasa is recorded from China for the first time. A key to the known adult males of Parakiefferiella from China is presented. The generic diagnosis of male Parakiefferiella given by Cranston et al. (1989) is emended.     

First record of the genus Dialarnaca Gorochov, 2005 from China,with description of two new species (Orthoptera,Gryllacrididae, Gryllacridinae)

In the present paper, Dialarnaca Gorochov, 2005 is recorded from China for the first time, with two new species of the genus described, Dialarnaca longicerca Shi & Bian, sp. n. and Dialarnaca zhoui Shi & Bian, sp. n. A key and a distribution map of the genus Dialarnaca, are provided.     

Cherax snowden,a new species of crayfish (Crustacea,Decapoda, Parastacidae) from the Kepala Burung (Vogelkop) Peninsula in Irian Jaya (West Papua), Indonesia

A new species, Cherax snowden sp. n., from the Oinsok River Drainage, Sawiat District in the central part of the Kepala Burung (Vogelkop) Peninsula, West Papua, Indonesia, is described, figured and compared with the closest related species, Cherax holthuisi Lukhaup & Pekny, 2006. This species is collected and exported for ornamental purposes and its commercial name in the pet trade is “orange tip” or “green orange tip”. Both species may be easily distinguished morphologically or by using sequence divergence, which is substantial, for considering Cherax snowden sp. n. to be a new species.
