Diagnosis.

Reddish brown; length 3.54-3.64; postgenae rounded laterally; antennomeres IX–XI enlarged; IX–X modified in male; pronotum roundly expanded laterally at anterolateral margins; male with short metaventral processes; metacoxae simple; aedeagus with asymmetric median lobe.

Description.

Male (Fig. 4A). Length 3.54-3.64. Head longer than wide, HL 0.76-0.80, HW 0.63-0.65; eyes each composed of about 40 facets. Antennal clubs as in Fig. 5A. Pronotum (Fig. 5B) slightly longer than wide, PL 0. 0.73-0.76, PW 0.69-0.71, roundly expanded laterally at anterolateral margins. Elytra wider than long, EL 0.93-0.94, EW 1.29-1.31. Metaventral processes (Fig. 5C) short, truncate apically. Procoxae, protrochanters and profemora spinose at ventral margin (Fig. 5D), protibiae with distinct triangular apical projection (Fig. 5E); mesotrochanters with small ventral spine, mesofemora broadly thickened ventrally (Fig. 5F), mesotibiae with small apical tubercle (Fig. 5G); metatrochanters and metafemora (Fig. 5H) simple, metatibiae with setose tuft near apices (Fig. 5I). Abdomen broad at base and narrowed apically, AL 1.12-1.14, AW 1.32-1.38. Sternite IX as in Fig. 3J. Aedeagus length 0.57, with asymmetric median lobe (Figs 5 K–M).

Female. Unknown.

Comparative notes.

Labomimus jizuensis is closely allied to Labomimus fimbriatus and Labomimus simplicipalpus as discussed above, it can be readily separated from both species by the clearly asymmetric aedeagal median lobe.

Distribution.

Southwest China: Yunnan.

Biology.

Individuals were collected by sifting litter and moss in mixed forests.

Etymology.

The new species is named after the locality where the two paratypes were collected, Jizushan Mountain.
