DEUVE ET AL.: CARABID BEETLE FAUNA OF THE GAOLIGONG MOUNTAINS 403
Basal margin nearly rectilinear. Lateral margination slender throughout and narrowly reflexed, lateral
grooves distinctly impressed. Single midlateral setae on each side inserted near anterior onethird;
single basolateral seta on each side, inserted slightly anterior to apex of basal angle.
Elytra. Ovoid, humeri distinct but rounded. Disc convex, with striae 1 to 3 or 4 finely
impressed, the more lateral striae successively more faintly impressed, striae 7 and 8 effaced, striae
slightly and irregularly punctate. Parascutellar striole rudimentary. Recurrent stria distinct, moderately
deep, terminated at the posterior end of stria 7. Basal setiferous pore present at common origin
of striae 1 and 2. Two discal setae present and inserted next to stria 3, one at anterior one-fourth
and one near middle of elytra. Preapical seta present and inserted in a prediscal position on interval
3, closer to stria 2 than 3 in most specimens (closer to stria 3 in a few) in forward position at
apical one-fourth of elytra.
Legs. Relatively 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. (Fig. 23b). Median lobe with basal bulb robust and with a thick sagittal
aileron; apical lamella elongate, slightly tapered, with apex blunt. Endophallus nearly unarmed,
with only a faintly sclerotized scaly area.
HABITAT DISTRIBUTION.— Members of this species have been found in a variety of microhabitats
in the alpine zone at elevations ranging from 3360 to 3950 m. Specimens were collected from
under stones in moist meadows, on tundra slopes and ridges with sparse to thick herbaceous vegetation
(Fig. 38a, 39b, 40a) and at the edges of small streams and seeps from talus slopes (Fig. 39a).
They were also collected in pitfall traps placed at the edges of Rhododendron thickets up to two
meters tall. Members of this species have been found syntopic with specimens of Queinnectrechus
(Gaoligongtrechus) balli, Queinnectrechus (s.str.) griswoldi, Queinnectrechus (s.str.) gongshanicus,
and Trechus qiqiensis at one or more sites.
GEOGRAPHICAL DISTRIBUTION WITHIN THE GAOLIGONG SHAN.— Fig. 23c. we examined a
total of 52 specimens (22 males and 30 females), all from Bingzhiongluo and Cikai Townships in
Gongshan County on the crest and eastern slope of the northern part of the Gaoligong Shan (see
Type material above for exact collection data). These localities are all in Core Area 2.
OVERALL GEOGRAPHICAL DISTRIBUTION.— This species currently is known only from Gongshan
County in the northern part of the Gaoligong Shan, in western Yunnan Province, China.
