Type material. Holotype. China: Guangxi: ♁, glued on a card with labels as follows: “ Xing’an County, Mao’ershan N. R., 2100 m, 10.VII.2011, Liang Tang leg.” “ Holotype / Barypalpus maoershanus / Li & Tang” [red handwritten label] (SHNU).

Description. (Habitus: Figs 46–48) 9.7 mm long (5.1 mm, abdomen excluded). Head black, antennae, mandibles dark reddish brown, palpi reddish, pronotum black, with anterior and posterior margin reddish, elytra black with base and posterior margin reddish brown, abdominal segments black, each with posterior margins broadly reddish.

Head rounded quadrangular, 1.2 times as wide as long, tempora subparallel, 1.7 times as long as eyes, dorsal surface densely punctate, punctation gradually becoming coarser toward base and tempora; antennae rather short, segments 4–5 slightly oblong, segment 7 about as long as wide, segments 8–10 transverse.

Pronotum 1.1 times as long as wide, sides subparallel, surface with micropunctation as dense as but much finer than on head; scutellum moderately coarsely and moderately densely punctate; elytra along sides longer than pronotum along midline, densely and coarsely punctate, with several markedly larger punctures scattered among ground punctuation sublaterally (Fig. 48); hypomera densely and moderately coarsely punctate

Abdomen as wide as elytra, abdominal tergites with rather dense and coarse drop-shaped punctation; posterior margin of tergite VII with whitish seam.

Aedeagus (Figs 125–128) with median lobe as long as paramere in lateral view, without hook apically, paramere with about 15 peg setae arranged in two irregular sublateral rows.

Distribution. China (Guangxi).

.

Diagnosis. The species is very similar to B. chinensis but differs in the following characters: body coloration darker; eyes smaller; pronotum longer; elytra (Fig. 45) with distinctly larger punctures sublaterally (absent in B. chinensis); median lobe (Figs 127, 128) as long as paramere with apex rounded (median lobe is longer than paramere, in lateral view median lobe with distinct subapical tooth in B. chinensis, Fig. 123, 124).

Etymology. Named after the type locality, Mao’ershan Mountain.
