Type material

(2 ♂♂). Holotype: ♂, labeled ‘CHINA: Yunnan, Baoshan Pref., Gao- / ligong Shan, 32 km SE Tengchong,/ 2150-2250 m, 24°51-53'N, 98°45'E, / devast. prim. and second. forest litter, / dead wood, mushrooms sifted, 26.VIII. / 2009, leg. M. Schülke [CH09-08/09]’ (cSch). Paratype: 1 ♂, same label data as holotype (cSch).

Diagnosis

Reddish brown; length 2.89–3.02; postgenae nearly rounded; antennomeres IX–XI enlarged, IX–X modified in the male; pronotum with lateral margins slightly angularly expanded laterally; metaventral processes short and sharp; metacoxae with large hook-like ventral protuberance; aedeagus with symmetric median lobe.

Description

Male (Fig. 6A). Length 2.89–3.02. Head longer than wide, HL 0.70–0.71, HW 0.66–0.69; eyes each composed of about 25 facets. Antennal clubs as in Fig. 7A. Pronotum (Fig. 7B) slightly longer than wide, PL 0.68–0.70, PW 0.64–0.65, with lateral margins slightly angularly expanded. Elytra wider than long, EL 0.75–0.76, EW 1.18–1.19. Metaventral processes short, narrowed apically with pointed apices (Fig. 7C). Protrochanters with small ventral spine, profemora with large sharp spine at ventral margin (Fig. 7D), protibiae (Fig. 7E) with distinct preapical apur; mesotrochanters (Fig. 7F) with indistinct tiny spine at ventral margin; metacoxae (Fig. 7G) with big hook-like protuberance at ventral margin, metatrochanters and metafemora simple. Abdomen broad at base and narrowed apically, AL 0.76–0.85, AW 1.23–1.26. Sternite IX as in Fig. 7H. Aedeagus length 0.60, median lobe symmetric, narrowed from base toward apex (Figs 7I–K).
Female. Unknown.

Comparative notes

This species is placed near Labomimus cognatus and Labomimus vespertilio described below by sharing a similar habitus, the short median metaventral process and the protuberant metacoxae. Labomimus sarculus can be readily separated from both species by the unique modified antennomeres IX, longer apical spur of protibiae and the aedeagus has the median lobe medially straight at the apex, not concave.

Distribution

Southwest China: Yunnan.

Biology

Individuals were sifted from leaf litter and mixed deadwood and mushrooms in a devastated primary and secondary forest.

Etymology

The Latin word ‘sarculus’ means ‘a hoe’, referring to the uniquely modified antennomeres IX.
