Type material

(3 ♂♂, 3 ♀♀). Holotype: ♂, labeled ‘CHINA Yunnan [CH07-11], Baoshan / Pref., Gaoligong Shan, m. Xiaoheishan / N.R., 35 km SE Tengchong, 2110 m, / 24°"50'16"N, 98°"45'43"E, decid forest, / litter, sifted, 30.V.2007, M. Schülke’ (cSch). Paratypes, 1 ♂, same label data as holotype (SNUC); 1 ♂, labeled ‘CHINA: Yunnan, Baoshan Pref., Gao- / ligong Shan, W pass, 32 km SE / Tengchong, 1600 m, 25°51'11"N, 98°44'27"E, cleft with devast. primary / forest, litter & mushr. sifted, 28.VIII. / 2009, leg.

Wrase [14]’ (cSch); 1 ♀, same label data, except ‘W pass, 35 km / SE Tengchong, 2100 m (devast. prim. / dec. forest, litter, sifted) / 24°50'18"N, 98°45'43"E / 25-28.VIII.2009 D.W. Wrase [06]’ (SNUC); 1 ♀, same label data, except ‘litter, wood, mushrooms sifted, 25.VIII. / 2009, leg. M. Schülke [CH09-06]’ (cSch).

Diagnosis

Reddish brown; length 3.18–3.48; postgenae nearly rounded; antennomeres IX–XI enlarged, IX–X modified in the male; pronotum with lateral margins moderately angularly expanded laterally; with short blunt metaventral processes; metacoxae spinose; aedeagus with symmetric median lobe.

Description

Male (Fig. 1A). Length 3.18–3.41. Head longer than wide, HL 0.71–0.78, HW 0.65–0.71; eyes each composed of about 40 facets. Antennal clubs as in Fig. 2A. Pronotum (Fig. 2B) slightly longer than wide, PL 0.71–0.75, PW 0.66–0.71, with lateral margins moderately angularly expanded laterally. Elytra wider than long, EL 0.84–0.90, EW 1.12–1.35. Short metaventral processes with rounded apices (Fig. 2C). Protrochanters with small ventral spine, profemora with large ventral spine (Fig. 2D), protibiae with small apical tubercle (Fig. 2E); mesotrochanters (Fig. 2F) with tiny spine at ventral margin; metacoxae (Fig. 2G) with long hook-like protuberance at ventral margin, metatrochanters and metafemora simple. Abdomen broad at base and narrowed apically, AL 0.92–0.98, AW 1.23–1.37. Sternite IX as in Fig. 2H. Aedeagus length 0.50, with symmetric median lobe (Figs 2I–K).
Female. Similar to male in general; BL 3.25–3.48, HL 0.73–0.76, HW 0.65–0.66, PL 0.76–0.77, PW 0.71–0.72, EL 0.80–0.86, EW 1.34–1.41, AL 0.96–1.09, AW 1.41–1.46. Eyes each composed of about 27 facets. Antennae lacking modification; metaventral processes absent.

Comparative notes

This is placed as a sister species of Labomimus vespertilio sp. n. described below. The two species share a similar general appearance, short metaventral process, similar placement of spines on the legs and a close aedeagal form. The two species can be readily separated by the smaller size, the symmetric antennomeres IX with a disc-like process and the median lobe has a narrower apex in Labomimus cognatus, while Labomimus vespertilio is larger in size, has strongly asymmetric antennomeres IX and has the aedeagus with median lobe much broader at apex.

Distribution

Southwest China: Yunnan.

Biology

Individuals were sifted from leaf litter in deciduous forests.

Etymology

The Latin word ‘cognatus’ means ‘related’, indicating a close relationship between the new species and Labomimus vespertilio described below.
