Description
Body length 5.78–6.34 mm, length of fore body 3.28–3.56 mm. Habitus as in Fig. 13A. Coloration: body black with bluish hue, elytra with yellowish to reddish spot reaching posterior but not lateral margins; legs blackish with dark-brownish tarsi; antennae dark-brownish.
Head as wide as long (HW/HL = 0.96–1.03), widest at eyes; posterior angles broadly rounded; punctation dense and moderately coarse, sparser in median dorsal portion; interstices without microsculpture. Eyes large, more than half as long as the distance from posterior margin of eye to neck in dorsal view. Antenna slender, 1.72–1.95 mm long.
Pronotum slender (PL/PW = 1.25–1.41, PW/HW= 0.92–1.0), lateral margins weakly convex in dorsal view, with impunctate midline, punctation similar to that of head, but distinctly sparser, interstices glossy.
Elytra longer than broad (EL/EW = 1.0–1.02, EW/PW = 1.24–1.33, EL/PL = 1.0–1.05); punctation coarse and dense, arranged in irregular series; interstices without microsculpture. Hind wings fully developed.
Abdomen narrower than elytra; punctation fine and dense; posterior margin of tergite VII with palisade fringe; posterior margin of tergite VIII strongly convex in the middle.
Male. Sternite VII (Fig. 13D) strongly transverse, posteriorly with pronounced median impression, this impression of somewhat triangular shape, without punctation and pubescence, posterior margin broadly and very weakly concave; sternite VIII (Fig. 3E) weakly transverse, postero-median impression with modified, stout and short black setae, posterior excision deep and moderately broad, on either side of this excision with long dark submarginal setae; aedeagus (Figs 13B, C) 1.36 mm long, with weakly asymmetric and apically acute ventral process.
Female. Unknown.
Etymology
The specific epithet refers to the famous late poet Yuan Qu, who was born in Yichang (Hubei), which is near the type locality.
Comparative notes
This species is similar to Lobrathium configens Assing (2012)[1] and Lobrathium spathulatum Assing (2012)[1] in external characters. It is distinguished from both by the broader ventral process in ventral view.
Habitat and distribution
The specimens were sifted from wet moss near a stream (Fig. 20C) in the Houhe National Reserve, Hubei (Fig. 19).
