7A2D4907FFD4FFFF18CDFA679787F8AE.taxon	description	Description: Male. Body (Fig. 1 A) length 2.2 mm; reddish brown. Head (Fig. 1 B) longer than wide, length from anterior margin of clypeus to head base (excluding occipital constriction) 0.43 mm, width across eyes 0.29 mm; anterior margin of clypeus angulate, pointed at middle; each eye composed of about 20 facets; antennomeres 3 and 4 each much longer than antennomeres 1 and 2 (Fig. 2 A); length of antennomeres 2 - 4 0.05, 0.23, 0.33 mm, respectively; antennomeres 4 slightly more than 1.4 times as long as antennomeres 3, broadening from base toward apex, apically truncate. Pronotum (Fig. 1 B) subglobose, about as long as wide, length along midline 0.44 mm, maximum width 0.42 mm. Elytra (Fig. 1 A) much wider than long, length along suture 0.58 mm, maximum width 0.84 mm; disc lacking linear microsculpture; with sub-triangular tufts of setae at posterolateral margins (Fig. 2 B). Prosternum (Fig. 2 E) roughly sculptured medially. Mesoventrite (Fig. 2 E) with short intercoxal ridge. Metaventrite (Fig. 2 E) convex, densely setose medially, lateral areas with distinct linear microsculpture. Mesotrochanters (Fig. 2 C) with large triangular ventral spine, mesofemora (Fig. 2 C) angulate on ventral margin at middle; metatrochanters (Fig. 2 D) with distinct ventral spine slightly smaller than that of mesotrochanters. Abdomen large, wider than long, much wider than elytra, length along midline 0.75 mm, maximum width 0.91 mm; composite tergite broadly and deeply concave mediobasally, with tufts of curved trichomes at basolateral region (Fig. 2 B), first pair of paratergites with curved trichome (Fig. 2 B). Sternite 6 (VIII) with bunch of short, thick setae at middle. Aedeagus (Fig. 2 F, G) moderately sclerotized, length 0.46 mm; median lobe at apex narrowing and strongly curved ventrad, with membranous part at dorso-apical side. Female. Unknown. Comparative notes: The males of the new species can be readily separated from those of all congeners by the relatively stouter habitus, the unique spination of the legs, and the configuration of the aedeagus. An identification key to males, updated from Yin & Li (2014), is provided below to aid in the discriminations of the Chinese species:	en	Yin, Zi-Wei, He, Li (2020): A new species of Diartiger Sharp from Sichuan, China (Coleoptera: Staphylinidae: Pselaphinae).
