First record of Tyrodes Raffray (Coleoptera, Staphylinidae, Pselaphinae) in China, with description of T. jenisi sp. n. from Yunnan Province

Keywords: Tyrodes jenisi Yin & Li, sp. n., of the pselaphine tribe Tyrini, from Yunnan, Southwest China is described, illustrated and distinguished from allied species mainly using aedeagal characters. This represents the first record of Tyrodes in China. Staphylinidae, Pselaphinae, taxonomy, Tyrodes, new species, China Introduction The small genus Tyrodes Raffray currently contains six valid species scattered in the Oriental (5 spp.) and Northeast Palaearctic (1 sp.) regions: Tyrodes histrio (Schaufuss, 1887) (Sri Lanka, type species), Tyrodes championi (Jeannel, 1960) (India), Tyrodes clavatus (Raffray, 1895) (Singapore), Tyrodes janetscheki Besuchet, 1970 (Nepal), Tyrodes setosus Jeannel, 1957 (Vietnam), and Tyrodes segrex Kurbatov, 1990 (Russian Far East) (Raffray 1895, 1908; Newton and Chandler 1989; Hlavac and Chandler 2005). Tyrodes is allied to the Holarctic and Oriental Tyrus Aube by sharing a similar general habitus, and similar forms of the maxillary palpi and pronotum. The two genera can be separated by the presence of an indistinct frontal fovea, the abdominal tergite IV (first visible tergite) being longer than tergite V, and the aedeagus being stouter and has a short median lobe in Tyrodes, while Tyrus has a distinct frontal fovea, the tergite IV is subequal to tergite V, and the aedeagus is more slender and bears a longer median lobe. In this paper, we report a new species of Tyrodes from Yunnan, Southwest China. A diagnosis, a description, and illustrations of male diagnostic features are provided. This also represents the first record of the genus in China.
