Diagnosis.

Reddish brown; medium-sized; genae rounded; antennomeres IX–XI strongly modified; pronotum with rounded lateral margins; with thin and long metaventral processes (in lateral view); pro- and metatibiae sinuate; aedeagus with asymmetric median lobe and small parameres.

Description.

Male (Fig. 1). Length 2.65-2.87. Head as long as wide, HL 0.56-0.58, HW 0.56-0.58; eyes large, each composed of about 40 facets. Antennal clubs as in Fig. 2A. Pronotum (Fig. 2B) slightly longer than wide, PL 0.55-0.56, PW 0.50-0.52, with round lateral margins. Elytra wider than long, EL 0.80-0.81, EW 0.99 -1.04. Metaventral horn-like processes long (Fig. 2H). Legs having protibiae with blunt and slightly serrate apical projection (Figs 2C, D); mesotrochanters with minute ventral spine (Fig. 2E); metatrochanters with large robust spine (Fig. 2F). Abdomen large, AL 0.74-0.92, AW 1.00-1.02. Sternite IX as in Fig. 2I. Aedeagus length 0.39; with long asymmetric median lobe; apical half of parameres membranous (Figs 2 J–L).

Female. Similar to male in general; BL 2.60-2.75, HL 0.56-0.58, HW 0.53-0.57, PL 0.56-0.58, PW 0.50-0.52, EL 0.67-0.70, EW 0.98-1.04, AL 0.81-0.89, AW 1.05-1.09. Eyes each composed of about 30 facets. Antennae simple; protibiae not spinose; metaventral horn-like processes absent.

Distribution.

South China: Hainan, Fujian.

Comparative notes.

Very distinctive species, easily separable from all other Pselaphodes species by the sinuate pro- and metatibiae, the metatibiae with a blade-shaped ventral tooth near apical 1/3, and the serrate ventral margin for the distance posterior to the tooth. The new species shares with Pselaphodes bomiensis Yin et al., 2011 and Pselaphodes condylus Yin et al., 2011 a similar placement of the antennal modification, but can be readily separated from both by the pronotal lateral margins being rounded. On the contrary the lateral margins of the pronotum are more or less angularly expanded laterally in Pselaphodes bomiensis and Pselaphodes condylus .

Etymology.

The species name is dedicated to Mei-Ying Lin for the collection of part of the type series.
