Type material

(4 ♂♂, 5 ♀♀). Holotype: ♂, labeled 'P. R. CHINA, Yunnan / Jizushan, 25°58'39"N, 100°21'14E / 28.VI.2011, 3216 m / sift27, V. Grebennikov’ (pcPH); Paratypes: 1 ♂, 4 ♀♀, same label data as holotype, except ' 25°58'18"N, 100°21'33N / 30.VI.2011, 2875 m / sift30' (pcPH, SNUC); 2 ♂♂, 1 ♀, labeled 'P. R. China, Hubei / Dabieshan, 31°06.013'N, 115°47.300'E / 11-21.VI.2008, 640 m / sifting, V. Grebennikov’ (pcPH, SNUC).

Diagnosis.

Reddish brown; length 3.31-3.37; postgenae rounded laterally; antennomeres IX–XI enlarged; antennomeres IX modified in male; pronotum rounded at anterolateral margins; male with long metaventral processes; metacoxae simple; aedeagus with asymmetric median lobe.

Description.

Male (Fig. 13B). Length 3.31-3.37. Head longer than wide, HL 0.71-0.73, HW 0.63-0.64; eyes each composed of about 25 facets. Antennal clubs as in Fig. 15A. Pronotum (Fig. 15B) slightly longer than wide, PL 0.69-0.71, PW 0.61-0.66, rounded at anterolateral margins. Elytra wider than long, EL 0.87-0.88, EW 1.23-1.29. Metaventral processes broad and long, apically narrowed (Fig. 15C). Protrochanters and profemora spinose ventrally (Fig. 15D), protibiae with tiny apical projection (Fig. 15E); mesotrochanters with two ventral spines, mesofemora simple (Fig. 15F); metatrochanters and metafemora simple (Fig. 15G). Abdomen broad at base and narrowed apically, AL 1.04-1.05, AW 1.28-1.30. Sternite IX as in Fig. 15H. Aedeagus length 0.70, with asymmetric median lobe (Figs 15 I–K).

Female. Similar to male in general; BL 3.36, HL 0.74, HW 0.61, PL 0.70, PW 0.65, EL 0.85, EW 1.29, AL 1.07, AW 1.38. Eyes each composed of about 20 facets. Antennae unmodified; metaventral processes absent.

Comparative notes.

This new species can be separated from the other species of the group by the metaventral processes being curved from the mid-length and then narrowed apically, the aedeagus with an elongate and apically truncate median lobe, the structure of the aedeagal endophallus, and its distribution.

Distribution.

Southwest China: Yunnan; Central China: Hubei.

Biology.

Individuals were sifted from leaf litter in forests.

Etymology.

The specific name refers to the long aedeagal median lobe of the new species.
