Diagnosis

Description
Male (Fig. 6B). Length 3.92. Head longer than wide, HL 0.89, HW 0.78; eyes each composed of about 20 facets. Antennal clubs as in Fig. 8A. Pronotum (Fig. 8B) slightly longer than wide, PL 0.76, PW 0.70, with lateral margins nearly rounded. Elytra wider than long, EL 0.89, EW 1.34. Metaventral processes short, apically narrowed (Fig. 8C). Protrochanters with tiny ventral spine, profemora simple (Fig. 8D); mesotrochanters (Fig. 8E) with one big spine and one smaller spine at ventral margin; metacoxae with elongate protuberance (Fig. 8F), metatrochanters and metafemora (Fig. 8G) simple. Abdomen broad at base and narrowed apically, AL 1.38, AW 1.37. Sternite IX as in Fig. 8H. Aedeagus length 0.62, asymmetric median lobe narrow (Figs 8I–K).
Female. Unknown.
Comparative notes
Labomimus schuelkei is placed close to Labomimus sichuanicus by sharing the postgenae being largely expanded laterally with a thickened posterior margin, and the strongly elongate antennomeres V–VIII. The two species can be readily separated by the large body size, the strongly modified antennomeres IX–X, and the aedeagus with the median lobe narrow dorsal-ventrally in Labomimus schuelkei, while Labomimus sichuanicus is much smaller (3.05–3.20 mm), has simple antennomeres IX–X, and has the aedeagus with a much broader median lobe (Hlaváč et al. 2000[1]).
Distribution
Northwest China: Shaanxi.
Biology
Probably sifted from leaf litter in a forest.
Etymology
Named after Michael Schülke, a well-known specialist in Staphylinidae, who kindly provided all the material used in this paper.
