DEUVE ET AL.: CARABID BEETLE FAUNA OF THE GAOLIGONG MOUNTAINS 397
striae 1 to 4 deeply impressed and not attenuated apically, stria 5 to 8 successively more faintly
impressed by still evident. Parascutellar striole present, short. Recurrent stria less abruptly interrupted
by a convexity and nearly continuous anteriorly with 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 discal position
on interval 3 next to stria 2 in forward position at apical one-fourth of elytra. Umbilicate setal
series with setae of humeral group equidistance from each other and setae of median group inserted
slightly posterior to middle.
Legs. Slightly short, protibiae with only a faint longitudinal furrow.
Abdomen. Abdominal ventrites glabrous, except for a single paramedial seta on each side, and
ventrite VII of female apically with two pairs of paramedial setae.
HABITAT DISTRIBUTION.— The unique holotype female of this species was found under a stone
in an open area cleared of forest but surrounded by bamboo thickets and scattered Abies, Rhododendron
and Prunus species at an elevation of 3290 m (Fig. 42b). One specimen of Trechus shibalicus
sp. nov. also was found at the same site.
GEOGRAPHICAL DISTRIBUTION WITHIN THE GAOLIGONG SHAN.— Fig. 21b. This species is
known from a single locality in Fugong County, on the eastern slope of the northcentral part of the
Gaoligong Shan (see Type material above for exact collection data). This locality is in Core
Area 3.
OVERALL GEOGRAPHICAL DISTRIBUTION.— This species currently is known only from the type
locality on the eastern slope of the northcentral part of the Gaoligong Shan, in western Yunnan
Province, China.

TYPE MATERIAL.— Holotype, a male, in IOZ, labeled: “CASENT 1017595”/ “CHINA, Yunnan,
Lushui County, Luzhang Township, Piana Road at Fengxue Yakou, N25.97228°/E98.68336°,
3150 m, 11 May 2005,”/ “Stop# 2005-007, D.H. Kavanaugh, H.B. Liang, C.E. Griswold, D.Z.
Dong & K.J. Guo collectors”/ “HOLOTYPE Trechus luzhangensis Deuve & Liang, sp. nov. designated
2016” [red label]. Paratypes (only 1): a female (in CAS) labeled same as holotype, except
first label “CASENT 1017596” and last label “PARATYPE Trechus luzhangensis Deuve & Liang,
sp. nov. designated 2016” [yellow label].
TYPE LOCALITY.— China, Yunnan, Lushui County, Luzhang Township, Pianma Road at
Fengxue Yakou [Pass], N25.97228°/E98.68336°, 3150 m.
ETYMOLOGY.— The species epithet, luzhangensis, is derived from the name of the township,
Luzhang, in which the type locality is found, and the Latin suffix, -ensis, denoting place.
DIAGNOSIS.— Adults of this species (Fig. 22a) can be distinguished from those of all other
species in the region by the following combination of character states: size medium (BL = 3.7 to
3.8 mm), apterous; body color dark piceous, shiny, elytra with interval 1, lateral margins and apicomedial
area reddish; tempora glabrous, convex, half as long as diameter of eyes; pronotum transverse
(ratio Pw/PL = 1.46), basal angles rectangular and sharp; elytra ovoid, convex, striae finely
impressed, striae 1 to 3 deeply impressed on disc, not attenuated apically, remaining striae successively
less distinct, the outermost very faint but still evident; recurrent stria terminated anteriorly
at distinct convexity of interval 7; two discal setae present, inserted on interval 3 next to stria 3;
preapical seta present and inserted in a discal position on interval 3, near stria 2 in forward position
near apical one-fourth of elytra; median lobe of male aedeagus (Fig. 22b) with moderate-sized
