Type material

(2 ♂♂, 1 ♀). Holotype: ♂, labeled 'CHINA: Anhui, Qianshan County / Tianzhu Shan National Park / 30°43'56"N, 116°27'11"E, 960 m / (mixed leaf litter, sifted) / 2006.iv.23, Hu & Tang leg.' (SNUC). Paratypes: 1 ♀, same label data as holotype (SNUC); 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).

Diagnosis.

Reddish brown; length 3.00-3.31; postgenae rounded laterally; antennomeres IX–XI enlarged; antennomeres IX modified in male; pronotum rounded at anterolateral margins; male with large metaventral processes; metacoxae simple; aedeagus with asymmetric median lobe.

Description.

Male (Fig. 7B). Length 3.00-3.31. Head longer than wide, HL 0.66-0.72, HW 0.60-0.64; eyes each composed of about 50 facets. Antennal clubs as in Fig. 9A. Pronotum (Fig. 9B) slightly longer than wide, PL 0.65-0.72, PW 0.62-0.68, rounded at anterolateral margins. Elytra wider than long, EL 0.87-1.00, EW 1.25 -1.34. Metaventral processes large, apically broadened (Fig. 9C). Protrochanters and profemora spinose ventrally (Fig. 9D), protibiae with tiny apical spur (Fig. 9E); mesotrochanters with small ventral spines, mesofemora simple (Fig. 9F); metatrochanters and metafemora simple (Fig. 9G). Abdomen broad at base and narrowed apically, AL 0.82-0.87, AW 1.20-1.31. Sternite IX as in Fig. 9H. Aedeagus length 0.60-0.66, with asymmetric median lobe (Figs 9 I–K).

Female. Similar to male in general; BL 3.26, HL 0.72, HW 0.64, PL 0.71, PW 0.65, EL 0.87, EW 1.25, AL 0.96, AW 1.31. Eyes each composed of about 26 facets. Antennae simple; metaventral processes absent.

Comparative notes.

This species can be separated from the other members of the group primarily by the large, apically concaved metaventral processes, the more robust aedeagus with short apical portion of the median lobe, the structure of aedeagal endophallus, and its distribution.

Distribution.

East China: Anhui; Central China: Hubei.

Biology.

Adults were collected by sifting mixed leaf litter in forests.

Etymology.

The new species is named after the province where the type locality is located.

Notes.

Slight differences in body size and structure of the aedeagal endophallus were observed between specimens from Tianzhushan Mountain and Dabieshan Mountain. Since both localities belong to the Dabieshan Mountain Range, and all specimens were collected at low altitude (below 1000 m), the differences are considered to be intraspecific variation.
