Type material

(2 ♂♂, 3 ♀♀). Holotype: ♂, labeled 'China: Guizhou Prov. / Suiyang County / Kuankuoshui N. R. / Baishaogou, 750-900 m / 2010.VI.05, Yin & Zhai leg.' (SNUC) Paratypes: 1 ♂, 2 ♀♀, same label data as holotype (SNUC); 1 ♀, same label data, except '2010.VI.03, Lu, Yin & Zhai leg.' (SNUC).

Diagnosis.

Reddish brown; length 2.99-3.27; postgenae rounded laterally; antennomeres IX–XI enlarged; antennomeres IX modified in male; pronotum rounded at anterolateral margins; male with short metaventral processes; metacoxae simple; aedeagus with asymmetric median lobe.

Description.

Male (Fig. 13A). Length 2.99-3.12. Head longer than wide, HL 0.71-0.72, HW 0.64-0.65; eyes each composed of about 40 facets. Antennal clubs as in Fig. 14A. Pronotum (Fig. 14B) slightly longer than wide, PL 0.68-0.71, PW 0.63-0.65, rounded at anterolateral margins. Elytra wider than long, EL 0.90-0.92, EW 1.23-1.25. Metaventral processes short, apically narrowed (Fig. 14C). Protrochanters and profemora spinose ventrally (Fig. 14D), protibiae with small apical projection (Fig. 14E); mesotrochanters with two ventral spines, mesofemora simple (Fig. 14F); metatrochanters and metafemora simple (Fig. 14G). Abdomen broad at base and narrowed apically, AL 0.70-0.77, AW 1.20-1.22. Sternite IX as in Fig. 14H. Aedeagus length 0.61, with asymmetric median lobe (Figs 14 I–K).

Female. Similar to male in general; BL 3.11-3.27, HL 0.71-0.73, HW 0.64-0.66, PL 0.70-0.71, PW 0.68-0.69, EL 0.90-0.95, EW 1.28-1.32, AL 0.80-0.88, AW 1.32-1.37. Eyes each composed of about 25 facets. Antennae unmodified; metaventral processes absent.

Comparative notes.

This species can be separated from the other members of the group by the short, apically narrowed metaventral processes, the apically rounded median lobe of the aedeagus, the structure of the aedeagal endophallus, and its distribution.

Distribution.

Southwest China: Guizhou.

Biology.

Adults were sifted from leaf litter along a road in a forest.

Etymology.

The new species is named after the type locality, Kuankuoshui Natural Reserve.
