Type material

(2 ♂♂, 5 ♀♀). Holotype: ♂, labeled 'CHINA, YunnaN, Cang Shan at Dali / 25°41'07"N, 100°06'58E / 2.VII.2011, 2714 m / sift33. V. Grebennikov’ (pcPH). Paratypes: 1 ♂, 5 ♀♀, same label data as holotype (pcPH, SNUC).

Diagnosis.

Reddish brown; length 3.21-3.55; postgenae rounded laterally; antennomeres IX–XI enlarged; VII and IX–XI modified in male; pronotum rounded at anterolateral margins; male with long, broad metaventral processes; metacoxae simple; aedeagus with asymmetric median lobe.

Description.

Male (Fig. 19B). Length 3.37-3.55. Head longer than wide, HL 0.76-0.80, HW 0.66-0.69; eyes each composed of about 40 facets. Antennal clubs as in Fig. 21A. Pronotum (Fig. 21B) about as long as wide, PL 0.71-0.75, PW 0.71-0.73, rounded at anterolateral margins. Elytra wider than long, EL 0.90-0.93, EW 1.32-1.37. Metaventral processes long, and broad (Fig. 21C). Protrochanters and pro femora spinose at ventral margins (Fig. 21D), protibiae with distinct blunt apical spur (Fig. 21E); mesotrochanters with small ventral spines, mesofemora simple (Fig. 21F); metatrochanters and metafemora simple (Fig. 21G). Abdomen broad at base and narrowed apically, AL 1.00-1.07, AW 1.29-1.38. Sternite IX as in Fig. 21H. Aedeagus length 0.57, with asymmetric median lobe (Figs 21 I–K).

Female. Similar to male in general; BL 3.21-3.31, HL 0.74-0.75, HW 0.61-0.62, PL 0.71-0.72, PW 0.69-0.71, EL 0.83-0.84, EW 1.31-1.32, AL 0.93-1.00, AW 1.36-1.37. Eyes each composed of about 25 facets. Antennae unmodified; metaventral processes absent.

Comparative notes.

This distinct species can be readily separated from all other members of the genus by the antennomeres IX being largely projecting mesally, the modified antennomeres VII, and the aedeagus with a long, apically rounded median lobe.

Distribution.

Southwest China: Yunnan.

Biology.

Individuals were collected by sifting leaf litter in a forest.

Etymology.

The new species is named after Vasily Grebennikov, collector of the type series.
