Type material

(4 ♂♂, 5 ♀♀). Holotype: ♂, labeled ‘CHINA: W-Hubei (Daba Shan) / pass E of Mt. Da Shengnongjia, / 12 km NW Muyuping, 31°30'N, / 110°21'E, 22.VII.2001, / leg. M. Schülke [C01-13E] // dry creek vaelly, mixed deciduous forest, dead wood, mushrooms, / moss, 1950-2050 m (sifted) / [C01-13E]’ (cSch). Paratypes: 2 ♂♂, 3 ♀♀, same label data as holotype (cSch, SNUC); 1 ♂, labeled ‘CHINA: S-Shaanxi (Qinling Shan) / pass on rd. Zhouzhi-Foping, / 105 km SW Xi’an, N-slope / 1880 m, 33°44'N, / 107°25'E / leg. M.

Schülke / Berlin // M. SCHÜLKE Coll. / Staphylinidae, Pselaphinae / Labomimus sp. 13 / S. Nomura det., 2005’.

Diagnosis

Reddish brown; length 2.36–2.96; postgenae broadly expanded laterally; antennomeres IX–XI enlarged, IX–X modified in the male; pronotum with round lateral margins; with long metaventral processes; metacoxae simple; aedeagus with asymmetric median lobe.

Description

Male (Fig. 1B). Length 2.85–2.96. Head slightly longer than wide, HL 0.63–0.66, HW 0.60–0.62; eyes each composed of about 25 facets. Antennal clubs as in Fig. 3A. Pronotum (Fig. 3B) as long as wide, PL and PW 0.57–0.59, with round lateral margins. Elytra wider than long, EL 0.69–0.71, EW 1.09–1.10. Metaventral processes long, broadened apically with truncate apices (Fig. 3C). Profemora with short triangular ventral spine (Fig. 3D), protibiae with small apical spur (Fig. 3E); mesotrochanters (Fig. 3F) with small spine and mesofemora angularly protuberant ventrally; metacoxae (Fig. 3G) with short ventral protuberance, metatrochanters and metafemora (Fig. 3H) simple. Abdomen broad at base and narrowed apically, AL 0.96–1.00, AW 1.16–1.20. Sternite IX as in Fig. 3I. Aedeagus length 0.57, with asymmetric median lobe elongate (Figs 3J–L).
Female. Similar to male in general; BL 2.36–2.50, HL 0.56–0.58, HW 0.49–0.50, PL 0.51–0.52, PW 0.50–0.52, EL 0.57–0.60, EW 1.09–1.10, AL 0.72–0.80, AW 1.19–1.22. Eyes each composed of about 20 facets. Antennae lacking modification; metaventral processes absent.

Comparative notes

The new species is closest to Labomimus shibatai K. Sawada, 1961 by sharing the laterally expanded postgenae and rounded pronotal lateral margins. Apart from the clearly different aedeagal form, the two species can be separated by the much smaller body size, the transverse antennomeres X, and the elongate antennomeres IX being angularly expanded at anteromedial margin in Labomimus dabashanus. Labomimus shibatai is much larger in size (3.5–3.8 mm), has elongate antennomeres X and enlarged and unmodified antennomeres IX.

Distribution

Central China: Hubei; Norwest China: Shaanxi.

Biology

Individuals were sifted from leaf litter and moss in deciduous forests.

Etymology

Named after the type locality ‘Dabashan Mountain’.
