The specimens treated in this study are deposited in the following public collections: The Insect Collection of Shanghai Normal University, Shanghai, P. R. China Naturhistorisches Museum Basel, Switzerland
The labels of type specimens are cited in their original spelling. A slash (/) is used to separate different labels.
All measurements are in millimeters. The following abbreviations are used: –length of the body from the anterior margin of the mandibles (in resting position) to the abdominal apex –length of the head from the anterior margin of the frons to the posterior margin of the head –maximum width of the head –length of the pronotum along the midline –maximum width of the pronotum –length of the elytra from the anterior margin to the posterior elytral margin along suture –maximum width of the elytra –length of the aedeagus from the apex of the ventral process to the base of the aedeagal capsule

Body length: 8.87–9.62 mm, fore body length: 4.67–5.06 mm. HL/HW=1.08–1.10, PW/HW=0.87–0.96, EL/PL=0.92–1.01. Antenna 3.50–3.78 mm long.

The specimens from Qianmutian, 1050–1250 m are of darker coloration than those from Qianmutian, 1300 m, and Tianmu Shan, 800–1150 m.
The specimens were sifted from debris and moss in moist habitats. Tianmu Shan is a mountain with high biodiversity in Lin’an City in northwestern Zhejiang province in eastern China, its altitude ranging from 300 to 1506 m (
(1 ♂, 1 ♀).
Body length 7.56–7.67 mm, length of fore body 3.50–3.73 mm. Habitus as in
Head distinctly transverse (HL/HW=0.90–0.91); posterior angles marked; punctation coarse and dense, sparser in median dorsal portion, interstices without microsculpture. Eyes large, more than half as long as distance from posterior margin of eye to neck. Antenna slender, 2.06–2.11 mm long.
Pronotum slender (PL/PW=1.17–1.21), 0.93–0.96 times as wide as head, lateral margins weakly convex in dorsal view; punctation dense, coarser than that of head, midline moderately broadly impunctate; interstices without microsculpture and glossy.
Elytra broad and moderately short (EL/EW=0.94–0.95, EW/PW=1.17–1.23, EL/PL=0.95–0.97); humeral angles marked; punctation coarse and arranged in distinct series, interstices without microsculpture and glossy. Hind wings fully developed.
Abdomen slightly broader than elytra; punctation fine and dense; posterior margin of tergite VII with palisade fringe; posterior margin of tergite VIII weakly convex, without appreciable sexual dimorphism.
The specific epithet (adjective) is derived from the Luoxiao Shan range where the type locality is situated.
This species is highly similar to
The specimens were sifted from moss on stones in two streams, Jiangxi, East China.
