Diagnosis
Reddish brown; length 3.14–3.43; postgenae rounded laterally; antennomeres IX–XI enlarged; antennomeres IX modified in male; pronotum rounded at anterolateral margins; male with broad metaventral processes; metacoxae simple; aedeagus with asymmetric median lobe.
Description
Male (Fig. 10B). Length 3.14–3.33. Head longer than wide, HL 0.69–0.72, HW 0.63–0.65; eyes each composed of about 40 facets. Antennal clubs as in Fig. 12A. Pronotum (Fig. 12B) slightly longer than wide, PL 0.65–0.68, PW 0.63–0.65, rounded at anterolateral margins. Elytra wider than long, EL 0.95–1.00, EW 1.28–1.32. Metaventral processes broad, apically narrowed (Fig. 12C). Protrochanters and profemora spinose ventrally (Fig. 12D), protibiae with tiny apical spur (Fig. 12E); mesotrochanters with two ventral spines, mesofemora simple (Fig. 12F); metatrochanters and metafemora simple (Fig. 12G). Abdomen broad at base and narrowed apically, AL 0.85–0.93, AW 1.26–1.31. Sternite IX as in Fig. 12H. Aedeagus length 0.61, with asymmetric median lobe (Figs 12I–K).
Female. Similar to male in general; BL 3.28–3.43, HL 0.75–0.80, HW 0.62–0.69, PL 0.71–0.72, PW 0.67–0.68, EL 0.87–0.93, EW 1.28–1.35, AL 0.95–0.98, AW 1.35–1.46. Eyes each composed of about 30 facets. Antennae unmodified; metaventral processes absent.
Comparative notes
This new species can be separated from the other members of the group primarily by the short, thick metaventral processes, the rather elongate and apically truncate median lobe of the aedeagus, the structure of the aedeagal endophallus, and its distribution.
Distribution
South China: Hainan.
Biology
Adults are commonly found in leaf litter of mixed forests.
Etymology
The new species is named after the Province where the type locality lies.
