DEUVE ET AL.: CARABID BEETLE FAUNA OF THE GAOLIGONG MOUNTAINS 391<br />
tened; frontal furrows deep, curved, prolonged and not attenuated posterior to the eyes. Two pairs<br />
of supraorbital setae present, the anterior pair inserted in foveae. Clypeus with four setae. Labrum<br />
with six setae, anterior margin distinctly concave. Mentum and submentum not fused but suture<br />
between them only faintly impressed. Mentum with medial tooth broad and apically truncate, about<br />
one-half the length of the lateral lobes. Submentum with six setae anteriorly. Gula wide. Genae<br />
with a single seta ventrally on each side. Antennae short, not quite extended to the basal one-fourth<br />
of elytra, male with about 2.5 to 3 antennomeres extended posteriorly beyond basal pronotal margin;<br />
antennomeres 2 and 3 about equal in length, antennomere 4 slightly shorter.<br />
Pronotum. Moderately transverse (ratio Pw/PL = 1.40), narrowed posteriorly, greatest width<br />
anterior to middle; lateral margins widely rounded, straightened only just anterior to basal angles,<br />
the latter small, but projected, acute and sharp. Disc convex, smooth and glabrous, median longitudinal<br />
impression sharply impressed, not quite extended to anterior margin; basal foveae distinct,<br />
subcircular; median basal area with several faint, longitudinal rugulae, delimited laterally by<br />
oblique furrows. Basal margin slightly bisinuate, slightly reflexed and oblique laterally, slightly<br />
projected medially. Lateral borders of pronotum moderately slender, regular, slightly reflexed, lateral<br />
grooves deeply impressed. Single midlateral setae on each side inserted slightly anterior to<br />
middle; single basolateral seta on each side, inserted at basal angle.<br />
Elytra. Ovoid, only very slightly elongate, more narrowed basally than apically, humeri distinct<br />
but rounded. Disc convex and smooth. Striae very finely punctate, striae 1 to 4 deeply<br />
impressed, stria 5 more faintly impressed, striae 6 to 8 effaced or nearly so. Parascutellar striole<br />
present. Recurrent stria terminated anteriorly by a slight convexity at the presumed location of stria<br />
7 apically. Basal setiferous pore present at common origin of striae 1 and 2. Two discal setae present<br />
and inserted next to stria 3, one at anterior one-fourth and one near middle of elytra. Preapical<br />
seta present and inserted in a discal position on interval 3, next to stria 3 in forward position at apical<br />
one-fourth of elytra. Umbilicate setal series with setae of humeral group equidistance from each<br />
other and setae of median group inserted slightly posterior to middle.<br />
Legs. Relatively short, protibiae with longitudinal furrow. Male protarsomeres 1 and 2 dilated<br />
and apicomedially toothed.<br />
Abdomen. Abdominal ventrites glabrous, except for a single paramedial seta on each side, and<br />
ventrite VII of males apically with one pair of paramedial setae, of females with four pairs.<br />
Male aedeagus. Median lobe (Fig. 19b) only slightly enlarged basally but with a large sagittal<br />
aileron present; shaft markedly narrowed at middle and broader subapically; apical lamella long,<br />
rectilinear, extremely thin in lateral view; endophallus voluminous but without well-defined sclerites.<br />
HABITAT DISTRIBUTION.— One specimen of this species was found under stones and debris<br />
along a roadcut (Fig. 41b) through slightly disturbed primary forest of Tsuga, with small, scattered<br />
small bamboo thickets; and the other specimen was found under stones along a small stream crossing<br />
the road in the same general area. No other trechines were collected in either of these sites,<br />
which range in elevation from 2200 to 2287 m.<br />
GEOGRAPHICAL DISTRIBUTION WITHIN THE GAOLIGONG SHAN.— Fig. 19c. we examined a<br />
total of 2 specimens, both from Mingguang Township in Tengchong County on the western slope<br />
of the southern part of the Gaoligong Shan (see Type material above for exact collection data). Both<br />
of these localities are in Core Area 6.<br />
OVERALL GEOGRAPHICAL DISTRIBUTION.— This species currently is known only from the<br />
western slope of the southern part of the Gaoligong Shan, in western Yunnan Province, China.
