Type material

(1 ♂). Holotype: ♂, labeled 'CHINA: Sichuan, Luding County / Hailuogou N. R., 28°35'47"N, 102°03'05"E, 2200-2300 m / (mixed leaf litter, sifted) / 2006.vii.27, Hu & Tang leg.' (SNUC).

Diagnosis.

Reddish brown; length 3.00; postgenae rounded laterally; antennomeres IX–XI enlarged; IX–X modified in male; pronotum roundly expanded laterally; male with long metaventral processes; metacoxae simple; aedeagus with symmetric median lobe.

Description.

Male (Fig. 7A). Length 3.00. Head slightly longer than wide, HL 0.65, HW 0.59; eyes each composed of about 40 facets. Antennal clubs as in Fig. 8A. Prono tum (Fig. 8B) slightly longer than wide, PL 0.61, PW 0.59, roundly expanded laterally. Elytra wider than long, EL 0.81, EW 1.06. Metaventral processes (Fig. 8C) long, broadened and truncate at apices. Procoxae, protrochanters and profemora spinose at ventral margin (Fig. 8D), protibiae with distinct triangular apical projection (Fig. 8E); mesotrochanters with distinct ventral spine, mesofemora simple (Fig. 8F), mesotibiae with small apical tubercle (Fig. 8G); metatrochanters and metafemora (Fig. 8H) simple, metatibiae with setose tuft near apices (Fig. 8I). Abdomen broad at base and narrowed apically, AL 0.93, AW 1.06. Aedeagus length 0.45, with symmetric median lobe (Figs 3 J–L).

Female. Unknown.

Comparative notes.

Labomimus simplicipalpus is closely related to Labomimus fimbriatus and Labomimus jizuensis as discussed above. The new species can be separated from Labomimus jizuensis by the symmetric aedeagal median lobe, from Labomimus fimbriatus by the smaller size, and the asymmetric antennomeres IX–X. The simple maxillary palpi of the new species are very unusual for Labomimus , and due to this the generic limit of Labomimus has to be expanded.

Distribution.

Southwest China: Sichuan.

Biology.

The single adult was collected from sifted mixed leaf litter in a forest.

Etymology.

The specific name refers to the simple maxillary palpi.
