DEUVE ET AL.: CARABID BEETLE FAUNA OF THE GAOLIGONG MOUNTAINS 369
Elytra. Elytral silhouette slightly tear-shaped, with humeri effaced, disc markedly convex,
smooth and glabrous. All discal striae effaced except for faintly impressed parascutellar striole and
a short, faintly impressed recurrent stria. Basal setiferous pore present. Three discal setae present,
aligned along presumed track of stria 3. Preapicale seta absent, one or two apicoangular setules
present. Umbilicate setal series with setae of humeral group equidistance from each other, with the
first slightly more medially inserted than the others, setae of median group inserted distinctly posterior
to middle.
Legs. Moderately long but slender. Protibiae with longitudinal furrow, sparely pubescent apically
on anterior surface. 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, females with two pairs.
Male aedeagus. Median lobe (Fig. 12b) large, elongate, broadest at mid-shaft, with apex long
and recurved dorsally; endophallus with internal sclerites acuminate apically.
COMMENTS.— Based on similarities in the form of the aedeagus of males, this species is closely
related to Queinnectrechus jiuhecola Deuve & Kavanaugh (Deuve et al. 2015), described from
Lijiang County, northwestern Yunnan. However, members of this new species are distinguished
from those of the latter by their much smaller size (BL = 5.3 to 5.8 mm in Q.jiuhecola members),
more elongate body form, more convex elytra, discal striae fully effaced (at least three medial striae
evident in Q.jiuhecola members) and, most significantly, preapical seta absent (present near
stria 2 subapically in Q.jiuhecola members).
In a recent paper, Belousov and Kabak (2016) established a new genus, Uenoites, in which
they placed Q.jiuhecola, as well as three other species previously included in Kozlovites or Deuveotrechus
Uéno (1995), based on the presence of a preapical seta, more convex tempora, and the
median lobe of the male aedeagus not markedly hooked apically. However, all these features are
plesiomorphic among trechines, which is problematic for demonstrating phylogenetic affinity of
the included taxa. Clearly, phylogenetic relationships among these groups of species remain unresolved.
As noted above, the genitalia of Q.griswoldi males are very similar to those of Q.jiuhecola
males, wherease those of the new species described below, Queinnectrechus gongshanicus sp.
nov., are of a very different form, although both of the new species described here are members of
genus Queinnectrechus.
HABITAT DISTRIBUTION.— Members of this species have been found in a variety of microhabitats
in the alpine zone near the crest of the Gaoligong Shan and the eastern slope, at elevations
ranging from 3270 to 3950 m. Specimens were collected under stones in moist meadows and on
tundra slopes and ridges with sparse to thick herbaceous vegetation (Figs. 37b, 38a, 38b, 39b), at
the edges of small streams and seeps from talus slopes, and at the edges of Rhododendron thickets
up to 1.5 m tall. Members of this species have been found syntopic with specimens of Queinnectrechus
(Gaoligongtrechus) balli sp. nov., Queinnectrechus (s.str.) gongshanicus sp. nov., Trechus
gongshanensis sp. nov., Trechus qiqiensis sp. nov. and Trechepaphiopsis monochaeta sp. nov.
GEOGRAPHICAL DISTRIBUTION WITHIN THE GAOLIGONG SHAN.— Fig. 12c. we examined a
total of 21 specimens (10 males and 11 females), all from the northern part of the Gaoligong Shan,
in Bingzhongluo and Cikai Townships, Gongshan County (see Type material above for exact collection
data). These localities are all on the crest or eastern slope of the Gaoligong Shan in Core
Area 2.
OVERALL GEOGRAPHICAL DISTRIBUTION.— This species currently is known only from the
northern part of the Gaoligong Shan, in western Yunnan Province, China.
