Pronotum (Fig. 19B) about as long as wide, PL 0.72, PW 0.71, with lateral margins slightly angularly expanded laterally. Elytra wider than long, EL 0.89, EW 1.37. Metaventral (Fig. 19C) processes narrowed apically. Protrochanters with short ventral spine, profemora with long sharp spine at ventral margin (Fig. 19D), protibiae with tiny apical spur (Fig. 19E); mesotrochanters with two small spines at ventral margin, mesofemora simple (Fig. 19F); metatrochanters and metafemora (Fig. 19G) simple.

Female. Unknown.

Comparative notes.

Placed near Pselaphodes erlangshanus and Pselaphodes flexus as discussed above, readily separated from both species by the unique antennomeres IX being strongly roundly projecting at the anterolateral margin.

Distribution.

Southwest China: Yunnan.

Biology.

Individuals was sifted from bamboo leaf litter and mushrooms in a secondary mixed forest.

Etymology.

The new species is named after the type locality, Zhongdian.
