Taxonomic study on the genus Pselaphodes Westwood (Coleoptera: Staphylinidae: Pselaphinae) from China. Part II

Abstract. This is the second paper of a series dealing with the Chinese fauna of the large genus Pselaphodes Westwood, 1870. Twelve new species and a new synonym are presented: P. bomiensis sp. nov. (Xizang); P. biwenxuani sp. nov. (Xizang); P. condylus sp. nov. (Guizhou); P. cuonaus sp. nov. (Xizang); P. fengtingae sp. nov. (Zhejiang); P. gongshanensis sp. nov. (Yunnan); P. hanmiensis sp. nov. (Xizang); P. jizushanus sp. nov. (Yunnan); P. meniscus sp. nov. (Sichuan); P. parvus sp. nov. (Guizhou); P. pectinatus sp. nov. (Hainan); P. wuyinus Yin et al., 2010 syn. nov. = P. tianmuensis Yin et al., 2010; and P. yanbini sp. nov. (Guizhou). New distributional data and discussion on intraspecific variations of P. tianmuensis and P. aculeus are provided. An updated key is given to assist in distinguishing all so far known Chinese species of Pselaphodes. A checklist of world species of Pselaphodes is also provided.

Dayao gen. n. of the subtribe Tyrina (Coleoptera, Staphylinidae, Pselaphinae) from South China

Abstract Dayao pengzhongi gen. et sp. n. is described and illustrated based on the material collected in Guangxi Province, South China. The genus is placed in the oriental ‘Pselaphodes complex’ of genera of the subtribe Tyrina and its taxonomic placement is discussed.

Two new species of Pselaphodes Westwood and new record of Taiwanophodes minor Hlaváč from South China (Coleoptera, Staphylinidae, Pselaphinae).

Abstract Two new species, Pselaphodes linae Yin & Li, sp. n. (Hainan, Fujian) and Pselaphodes shii Yin & Li, sp. n. (Hainan) are described from South China. Taiwanophodes minor Hlaváč is reported from outside Taiwan for the first time. Illustrations of major diagnostic features are provided for all treated taxa. The latest key to Chinese Pselaphodes is modified to include the new species.

Pengzhongiella daicongchaoi gen. et sp. n., a remarkable myrmecophile (Staphylinidae, Pselaphinae, Batrisitae) from the Gaoligong Mountains

Abstract A new genus and species, Pengzhongiella daicongchaoi, of the subtribe Batrisina (Batrisitae: Batrisini) is described from the Gaoligong Mountains, Yunnan, Southwest China. Adults were collected in a colony of Odontomachus monticola, and presented reduction of certain external characters and elongate appendages relating to myrmecophily. Description and illustrations of the habitus and major diagnostic features of the new taxon are provided; a brief discussion of its taxonomic placement is included. The new species also represents the first record of a Pselaphinae in association with an Odontomachus ant.

Two new species and new record of Batricavus Yin & Li (Coleoptera, Staphylinidae, Pselaphinae) from China.

Abstract Two new species, Batricavus abdominalis Yin & Li, sp. n. and Batricavus hainanensis Yin & Li, sp. n. are described from Hainan, South China, with male habitus and major diagnostic features illustrated. Batricavus tibialis Yin & Li is newly recorded from Zhejiang, East China. Keys to both sexes of the genus are included.

A new species of Acetalius Sharp from eastern China (Coleoptera, Staphylinidae, Pselaphinae)

Abstract The genus Acetalius Sharp currently contains two species from Japan. In this paper, a third species, Acetalius grandis Yin & Li, sp. n., is described from eastern China. The foveal pattern of Acetalius, and polymorphism and major diagnostic features of Acetalius grandis are figured. An updated key to Acetalius species is provided.

Fifteen Chinese species are recognized and all described here as new: Sathytes cristatus sp.nov., Sathytes excertus sp.nov., Sathytes perpusillus sp.nov., Sathytes rarus sp.nov., Sathytes tangliangi sp.nov., Sathytes tibialis sp.nov., Sathytes usitatus sp.nov. and Sathytes yunanicus sp.nov. from Yunnan; Sathytes larinus sp.nov. and Sathytes wuyishanus sp.nov. from Fujian; Sathytes longitrabis sp.nov. from Shaanxi; Sathytes longwangshanus sp.nov. and Sathytes paulus sp.nov. from Zhejiang; Sathytes magnus sp.nov. from Xizang; and Sathytes sichuanicus sp.nov. from Sichuan. Illustrations of major diagnostic characters of the new species are given. A total of 33 species worldwide are placed into seven newly defined groups. A checklist of Sathytes is also provided.

On the Chinese species of the genus Intestinarius Kurbatov (Coleoptera, Staphylinidae, Pselaphinae)

Abstract A total of three Chinese species of the genus Intestinarius Kurbatov, 2007 are recognized, among which, two new species are described: Intestinarius guangdongensis sp. n. from Guangdongand Intestinarius longiceps sp. n. from Guizhou. Illustrations of major diagnostic characters are given for all three Chinese species including Intestinarius kuzmini Kurbatov, 2007. A key is included to aid in their identification.
