Callosa gen. n., a new troglobitic genus from southwest China (Araneae, Linyphiidae).

ABSTRACT: A new linyphiid genus Callosagen. n., with two new species Callosa ciliatasp. n. (??, type species) and Callosa baiseensissp. n. (??), from southwest China are described. Detailed description of genitalic characters and somatic features is provided, as well as light microscopy and SEM micrographs of each species. Callosagen. n. was found in caves in Yunnan and Guangxi, and its copulatory organs are similar to those of Bathyphantes and Porrhomma, but differ greatly in details. The monophyly and placement of Callosagen. n. are supported by the results of molecular analysis.

Project description:A new genus of the subfamily Coelotinae F.O. Pickard-Cambridge, 1893, Sinodraconariusgen. n., with four new species, S. cawarongensissp. n. (??), S. muruoensissp. n. (??), S. sangjiuensissp. n. (??, type species), S. yuisp. n. (??) and S. patellabifidus (Wang, 2003) comb. n., ex. Draconarius Ovtchinnikov, 1999 is described. The genus is restricted to Southwest China. Sinodraconariusgen. n. is most similar to Draconarius but can be distinguished by the shape of the copulatory organs. The DNA barcodes of all species were documented for future use.

Acanoides gen. n., a new spider genus from China with a note on the taxonomic status of Acanthoneta Eskov & Marusik, 1992 (Araneae, Linyphiidae, Micronetinae).

Project description:A new "micronetine" genus Acanoides gen. n. is erected to accommodate two species from China: Acanoides beijingensis sp. n. as the type species and Acanoides hengshanensis (Chen & Yin, 2000), comb. n., with the females described for the first time. The genitalic characters and somatic features of the new genus were studied by means of light microscopy and scanning electron microscopy (SEM). The monophyly of the new genus was tested by a phylogenetic analysis based on molecular data. Descriptions of the new genus, the new species and the new combination are presented; SEM images and microscopy pictures of somatic and genitalic characters are provided in detail. To distinguish from other genera with similar genitalic characters, we compare the new genus with the species of Acanthoneta Eskov & Marusik, 1992, Epibellowia Tanasevitch, 1996 and Wubanoides Eskov, 1986. Four putative synapomorphies for Acanoides gen. n. are suggested to support its monophyly that could be tested in the future. Furthermore, redescriptions of the epigynal morphology of Acanthoneta aggressa Chamberlin & Ivie, 1943 (Nearctic) and on the male of A. dokutchaevi Eskov & Marusik, 1993 (Far East Asia, firstly recorded from China) are provided. Based on comparison with Poeciloneta, from which Acanthoneta stat. n. was separated by Saaristo and Tanasevitch (1996), a revised diagnosis is proposed to support the generic status.

On the desmitracheate "micronetine" genus Nippononeta Eskov, 1992 (Araneae, Linyphiidae).

Project description:The desmitracheate system in a "micronetine" genus Nippononeta Eskov, 1992 is recognized for the first time in the present study. This makes the subfamilial placement of this genus problematic. A morphological study was conducted for Nippononetakurilensis Eskov, 1992 (the type species of Nippononeta) and Nippononetacoreana (Paik, 1991). Characters of genitalia and tracheal system, as well as some somatic characters were studied in detail by using scanning electronic microscopy (SEM), and compared with those of Agyneta. Updated descriptions of the genus Nippononeta and its two species are presented. Putative synapomorphies for Nippononeta and Agyneta are provided, as well as some putative synapomorphies shared by the two genera. The results imply that both scaped epigynum and desmitracheate tracheal system are probably homoplastic. The placement of Nippononeta and Agyneta within Linyphiidae need to be resolved in future studies.

A review of the Holarctic genus Tmeticus Menge, 1868 (Araneae, Linyphiidae), with a description of a new genus.

Project description:Eight species attributed to Tmeticus are reviewed; five are redescribed and illustrated: Tmeticus affinis (Blackwall, 1885), Tmeticus bipunctis (Bösenberg & Strand, 1906), Tmeticus nigriceps Kulczy?ski, 1916, Tmeticus ornatus (Emerton, 1914) and Tmeticus tolli Kulczy?ski, 1908. The new genus, Paratmeticus gen. n. is erected for Tmeticus bipunctis, and a new combination is established: Paratmeticus bipunctis (Bösenberg & Strand, 1906), comb. n. Three species names: Gongylidium vile Kulczy?ski, 1885, syn. n., Tmeticus difficilis Kulczy?ski, 1926, syn. n. and Tmeticus dubius Kulczy?ski, 1926, syn. n., are synonymized with Tmeticus tolli Kulczy?ski, 1908. Although Gongylidium vile has date priority over Tmeticus tolli it is synonymized because of the lack of usage. Three species from Japan attributed to Tmeticus: Tmeticus neserigonoides Saito & Ono, 2001, Tmeticus nigerrimus Saito & Ono, 2001 and Tmeticus vulcanicus Saito & Ono, 2001 are not related to Tmeticus affinis, the type species of the genus, and their affinities remain unclear. The male of Tmeticus nigriceps is described for the first time.
