Elytra. Ovoid, not or only slightly elongate, about equally narrowed anteriorly and posteriorly,
humeri distinct but rounded. Disc convex, striae faintly impressed and finely punctate, the medial
three or four striae distinctly impressed, the more lateral striae more or less effaced, bearly perceptible.
Parascutellar striole present, longer than average for genus. Recurrent stria abruptly terminated
anteriorly in presumed location of posterior end of stria 5. Parascutellar setiferous pore
present at base at common origin of discal striae 1 and 2. Only one discal setiferous pore present,
inserted at anterior two-fifth of elytral length next to stria 3. Preapical seta present on interval 3
next to stria 2 and about equidistant from apical and sutural elytral margins. Umbilicate setal series
with setae of humeral group equidistance from each other and setae of median group inserted
slightly posterior to middle.
Legs. Short, protibiae with longitudinal furrow. Male protarsomeres 1 and 2 dilated and apicomedially
toothed.
Abdomen. Abdominal ventrites glabrous, except for a single paramedial seta on each side, and
ventrite VII of males apically with one pair of paramedial setae, of females with two pairs.
Male aedeagus. Median lobe (Fig. 29b) with sagittal aileron moderate in size, shaft broad
basally, then gradually narrowed apically to a broadly rounded apex; endophallus with a large,
scaly sclerorized area with two parts or folds.
HABITAT DISTRIBUTION.— Members of this species have been collected in pitfall traps set in
slightly disturbed broadleaf forest with large trees, dense understory of ferns and other herbs, and
a deep leaf litter layer, and also by sifting leaf litter in this same habitat. One specimen was beaten
from roadside vegetation with suspended leaf and twig debris in that vegetation in the same area.
One specimen was collected at a higher elevation (3100 m) from under stones in a rocky open areas
cleared by snow avalanches but shaded by three meter high herbaceous cover (Fig. 40b). Specimens
of Trechus shiyueliang, T.shibalicus and Trechepaphiopsis unipilosa sp. nov.were found syntopic
with the specimen of T.unisetulosa at this last site.
GEOGRAPHICAL DISTRIBUTION WITHIN THE GAOLIGONG SHAN.— Fig. 29c. we examined a
total of 27 specimens (13 males and 14 females) from sites on the eastern slope of the northcentral
part of the Gaoligong Shan in Fugong County (see Type material above for exact collection data).
All of these sites are in Core Area 3.
OVERALL GEOGRAPHICAL DISTRIBUTION.— This species currently is known only from Fugong
County in the northcentral part of the Gaoligong Shan region, western Yunnan Province, China.
