DEUVE ET AL.: CARABID BEETLE FAUNA OF THE GAOLIGONG MOUNTAINS 411<br />
Trechepaphiopsis unisetosa (Deuve), 2004 (sp. 2)<br />
(Figs. 27, 37a, 43b, 46–48)<br />
Trechus unisetosus Deuve, 2004: 220. Holotype, a female, in SCAU. Type locality: China, Yunnan, Gaoligong<br />
Shan, Lushui County, Fengxue Yakou [Pass], 2600-2700 m.<br />
Trechepaphiopsis unisetosa (Deuve), NEW COMBINATION<br />
DIAGNOSIS.— Adults of this species (Fig. 27a) can be distinguished from those of all other<br />
species in the region by the following combination of character states: size medium (BL = 3.1 to<br />
3.5 mm), apterous; body color light brown, dorsum slightly iridescent; eyes small but convex; tempora<br />
very convex, sparsely pubescent; pronotum transverse (ratio Pw/PL = 1.35), with basal<br />
angles obtuse and rounded; elytra convex, with median 2 or 3 striae deeply impressed, lateral striae<br />
faintly impressed to effaced; recurrent stria terminated anteriorly in presumed location of interval<br />
6; only one discal setiferous pore present, inserted at anterior one-third next to stria 3; preapical<br />
seta present, inserted next to stria 2; median lobe of male aedeagus (Fig. 27b) highly distinctive,<br />
with ventral margin of shaft sinuous and apex short and thin in lateral view, with broad apical<br />
projects in ventral view; endophallus without sclerites, but with a long tubular sleeve covered with<br />
long, slender spines.<br />
COMMENTS.— Among males of all the species of Trechepaphiopsis, those of T.unisetosa have<br />
an endophlallus most like that typical for members of the Epaphiopsis complex of genera, especially<br />
of certain species of Epaphius described from China (Jeannel 1962, Deuve 1992b). These<br />
also have a long tubular sleeve covered with long spines, symmetrically arranged in ventral view<br />
(Fig. 27c)<br />
HABITAT DISTRIBUTION.— Members of this species have been found in mixed broadleaf evergreen/<br />
deciduous forest at elevations ranging from 2460 to 2470 m and collected using both pitfall<br />
traps and sifting of leaf litter from the forest floor (Fig. 37a). Specimens of Trechepaphiosisuniporosa<br />
sp. nov and Trechepaphiama goaligong sp. nov were collected in the same sifted leaf litter<br />
samples and are therefore syntopic with T.unisetosa at this site. Additional specimens of T.unisetosa<br />
were collected in pitfall traps set in Rhododendron and bamboo thickets on the east flank of<br />
the summit ridge just south of the Fengxue Yakou at 3150 m (Fig. 43b), a site slightly above the<br />
type locality for the species.<br />
GEOGRAPHICAL DISTRIBUTION WITHIN THE GAOLIGONG SHAN.— Fig. 27d. we examined a<br />
total of 25 specimens (10 males and 16 females) from the following localities: Lushui County:<br />
Luzhang Township (100 m S of Fengxue Yakou on east side of pass, 3150 m,<br />
N25.97195°/E97.68381°, 11-21 May 2005, D.H. Kavanaugh, C.E. Griswold & K.J. Guo collectors<br />
[1 male and 1 female; CAS, IOZ]); Pianma Township (9.3 km ENE of Pianma along road to Lushui<br />
at Changyan He, 2460-2470 m, N25.99363°/E97.66651°, 15-18 October 1998, D.H. Kavanaugh,<br />
C.E. Griswold, C. Ferraris & C.L. Long collectors [7 males, 12 females; CAS, IOZ, MNHN], 12-<br />
21 May 2005, D.H. Kavanaugh, C.E. Griswold & K.J. Guo collectors [2 male and 2 females; CAS,<br />
IOZ]).<br />
Members of this species have been collected only in the southcentral part of the study area, on<br />
both western and eastern slopes of the Gaoligongshan, which are in Core Areas 4 and 5, respectively.<br />
OVERALL GEOGRAPHICAL DISTRIBUTION.— This species currently is known only from Lushui<br />
County in the southcentral part of the Gaoligong Shan region, western Yunnan Province, China.
