Diagnosis.

Reddish brown; medium-sized; postocular margins rounded; antennomeres IX strongly modified; pronotum angularly expanded laterally; with robust and long metaventral processes (in lateral view); aedeagus with asymmetric median lobe and long parameres.

Description.

Male (Fig. 3). Length 2.85-2.95. Head as long as wide, HL 0.56-0.60, HW 0.58-0.59; genae rounded; eyes large, each composed of about 40 facets. Antennal clubs as in Fig. 4A. Pronotum (Fig. 4B) almost as long as wide, PL 0.55-0.56, PW 0.57-0.58, with angulate anterolateral margins. Elytra wider than long, EL 0.81-0.84, EW 1.07-1.10. Metaventral horn-like processes long (Fig. 2G). Legs having protibiae with blunt and slightly serrate apical projection (Figs 2C, D); mesotrochanters with distinct ventral spine (Fig. 2E); metatrochanters with long, apically blunt spine (Fig. 2F). Abdomen large, AL 0.93-0.95, AW 1.08-1.12. Sternite IX as in Fig. 2H. Aedeagus length 0.59; with broad asymmetric median lobe and elongate parameres (Figs 4 I–K).

Female. Unknown.

Comparative notes.

This species is placed close to Pselaphodes bomiensis , Pselaphodes condylus and Pselaphodes jizushanus Yin et al., 2011 by sharing a similar placement of the antennal modification and projected anterolateral margins of the pronotum. It can be readily separated from Pselaphodes bomiensis and Pselaphodes condylus by the much smaller size and different form of the antennomeres IX, from Pselaphodes jizushanus by the metaventral processes being slightly curved posteriorly, the metatrochanters being protuberant ventrally and the metatibiae being simple. Pselaphodes jizushanus has the metaventral processes being curved anteriorly, the metatrochanters are simple, and the metatibiae are bluntly projected at apical 1/5.

Etymology.

The species is named after Hong-Liang Shi for the collection of the holotype.
