description: Trechepaphiopsis asetosa (Uéno), 1997   
(Figs. 25, 46–48)  
 Trechus (s. str.) asetosus Uéno, 1997: 185. Holotype, a male, in NMST. Type locality: China, Yunnan, Gaoligong Shan, Tengchong County, Dabei, 2430 m.   
 Trechepaphiopsis asetosa (Uéno), NEW COMBINATION   
 NOTES ON TYPE MATERIAL.— We have not had an opportunity to study the holotype or any other specimens of this species. Features noted below are based on Uéno’s (1997) original description and illustrations.   
 DIAGNOSIS.— Adults of this species (see Uéno 1997, Fig. 2) can be distinguished from those of all other species in the region by the following combination of character states: size small to medium (BL= 3.0 to 3.5 mm), apterous; body color dark brown to piceous, dorsum slightly iridescent; eyes very small, flattened, not projected laterally beyond tempora; tempora convex, slightly inflated; pronotum large and transverse (ratio PW/PL = 1.32 to 1.49), widest near anterior two-fifths, lateral margins slightly more curved in apical half than in basal half, basal angles obtuse and rounded; elytra ovoid, relative long and narrow, convex, striae 1 and 2 distinct, nearly complete and finely punctate, striae 3 and 4 faintly evident, stria 5 to 7 effaced, striae 8 evident but interrupted in apical half; recurrent stria terminated anteriorly in presumed location of interval 6; discal setae absent; preapical seta present, inserted next stria 2, inserted closer to sutural than to apical margin; median lobe of male aedeagus (see Uéno 1997, Figs. 3 and 4) with apex short and narrow, faintly recurved dorsally, endophallus without sclerites, but covered with scales.   
 HABITAT DISTRIBUTION.— According to Uéno (1997), members of this species were collected by sifting moist leaf litter accumulations on the ground in the “ Rhododendron zone” at elevations ranging from 2340 to 2440 m. At one of three sites where specimens of T. asetosa were found (at 2340 m), specimens of Minutotrechus minutus were also collected in the same litter samples.   
 GEOGRAPHICAL DISTRIBUTION WITHIN THE GAOLIGONG SHAN.— Fig. 25. We examined a single paratype specimen from the type locality, the only site from which the species has been recorded, in eastern Tengchong County in the southern part of the Gaoligong Shan region. This site is in Core Area 6.   
 OVERALL GEOGRAPHICAL DISTRIBUTION.— This species currently is known only from the type locality, in eastern Tengchong County in the southern part of the Gaoligong Shan, in western Yunnan Province, China.
