Agonotrechus yunnanus Uéno, 1999<br />
(Figs. 10, 46–48)<br />
Agonotrechus yunnanus Uéno, 1999a:215. Holotype,<br />
a male, in NSMT. Type locality: China,<br />
Yunnan, Gaoligong Shan, Longyang County,<br />
24.95°/ 98.75°, 2200-2500 m.<br />
NOTES ON TYPE MATERIAL.— we have not<br />
had an opportunity to study the unique holotype<br />
of this species, so features noted below<br />
are taken from Uéno’s orginal description.<br />
DIAGNOSIS.— Adults of this species (see<br />
Uéno 1999a, Fig. 1) can be distinguished from<br />
those of all other species in the region by the<br />
following combination of character states: size<br />
slightly small for the genus (BL = 5.4 mm);<br />
eyes large and projected; tempora short; pronotum<br />
rather small and only slightly transverse<br />
(ratio Pw/PL = 1.28), lateral explanation slender<br />
anteriorly, slightly widened basally, basal<br />
angles subrectangular and sharp; elytra with<br />
intervals only slightly convex, discal striae<br />
deeply impressed and punctate, two discal<br />
setae (anterior and middle) present near stria 3;<br />
median lobe of aedeagus of male (see Uéno<br />
1999a, Figs. 2–3) with apex short and broadly<br />
rounded.<br />
HABITAT DISTRIBUTION.— Although no<br />
precise habitat information accompanied the<br />
unique holotype specimen, Uéno (1999a:219)<br />
suggested it was probably collected near the<br />
pass across the crest of the Gaoligong Shan on<br />
the route from “Bawan to Shang’ying, which<br />
lies near the lower edge of the Rhododendron<br />
zone.” According to Uéno (1999a), specimens<br />
of Trechus indicus Putzeys (which he recorded<br />
as Trechus macrops Jeannel) and Epaphiotrechus<br />
fortipes (Uéno) comb. nov. were<br />
also collected in the same area.<br />
GEOGRAPHICAL DISTRIBUTION WITHIN<br />
THE GAOLIGONG SHAN.— Fig. 10. Longyang<br />
County: N24.95°/E98.75°, 2200-2500 m, 8-16<br />
May, O. Semala collector [1 male; NSMT]. No<br />
specimens of this species were collected during<br />
this study.<br />
The type locality for this species is on the<br />
eastern slope of the southern part of the<br />
