namely T.unisetosa (Deuve) and T.uniporosa sp. nov. (in Core Area 4). Two species, T.unisetulosa
sp. nov. and T.unipilosa sp. nov. occur in the same general area but apparently have different,
non-overlapping altitudinal ranges. So, at least for the present, locality data may aid in tentative
identifications of females and undissected males, except for the first two species mentioned above.

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 irides-
