Type material

(5 ♂♂, 2 ♀♀). Holotype: ♂, labeled 'CHINA: Zhejiang, Ningbo City / Yinzhou District, Tiantong Shan / 29°48'03"N, 121°46'56E, 600 m / (mixed leaf litter, sifted) / 2009.iv.26, Ting Feng leg.' (SNUC). Paratypes: 4 ♂♂, 2 ♀♀, same label data as holotype (SNUC).

Diagnosis.

Reddish brown; length 3.28-3.45; 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. 16B). Length 3.34-3.45. Head longer than wide, HL 0.75-0.77, HW 0.67-0.68; eyes each composed of about 35 facets. Antennal clubs as in Fig. 18A. Pronotum (Fig. 18B) slightly longer than wide, PL 0.71-0.72, PW 0.66-0.69, rounded at anterolateral margins. Elytra wider than long, EL 1.00-1.01, EW 1.29-1.34. Metaventral processes short, apically narrowed and curved posteriorly (Fig. 18C). Protrochanters and profemora spinose ventrally (Fig. 18D), protibiae with indistinct apical projection (Fig. 18E); mesotrochanters with multiple ventral spines, mesofemora simple (Fig. 18F); metatrochanters and metafemora simple (Fig. 18G). Abdomen broad at base and narrowed apically, AL 0.88-0.95, AW 1.29-1.31. Sternite IX as in Fig. 18H. Aedeagus length 0.78, with asymmetric median lobe (Figs 18 I–K).

Female. Similar to male in general; BL 3.28-3.37, HL 0.76-0.77, HW 0.63-0.66, PL 0.69-0.71, PW 0.69-0.70, EL 0.93-0.95, EW 1.29-1.35, AL 0.90-0.94, AW 1.34-1.40. Eyes each composed of about 30 facets. Antennae unmodified; metaventral processes absent.

Comparative notes.

This new species can be separated from the other species of the group by the short, apically curved and narrowed metaventral processes, the aedeagus with the median lobe being roundly broadened near apex, the structure of the aedeagal endophallus, and its distribution.

Distribution.

East China: Zhejiang.

Biology.

Individuals were sifted from mixed leaf litter of a forest.

Etymology.

The new species is named after the type locality, Tiantongshan National Forest Park.
