Subgenus Gaoligongtrechus Deuve and Kavanaugh , subgen. nov.

TYPE SPECIES.— Queinnectrechus (Gaoligongtrechus) balli sp. nov.

DERIVATION OF GENUS GROUP NAME.— The genus group name (masculine) is a combination of Gaoligong , the name of the mountain range where this taxon was discovered, and the genus name Trechus .

DIAGNOSIS.— Adults of this subgenus ( Fig. 14a ) can be recognized by the following combination of character states: size moderate (BL = 4.3 to 4.8 mm), apterous, body dark and very shiny, micaceous; head slightly elongate, eye small, their diameter less than length of tempora; right mandibles tridentate; mentum and submentum fused; pronotum narrowed posteriorly, narrowly cordate, pronotal disc markedly convex and glabrous, basal angles acute but without digitiform extensions, basal margin roundly convex and fitted to concave elytral base, laterally with two or three anteromedial setae and a single basal seta on each side; elytral silhouette tear-shaped, widest distinctly posterior to middle, humeri effaced, disc very convex and smooth, without distinct discal striae, except recurrent stria short but distinctly impressed, with four to six discal setae aligned near presumed location of stria 3, preapical seta present; abdominal ventrite IV to VI each with a pair of paramedial setae; male aedeagus with median lobe rather slender, bent basally about 90° to shaft, endophallus with a pair of slender sclerites tapered to points on both ends.

GEOGRAPHICAL DISTRIBUTION.— At present this subgenus includes the single species described below, which is known only from the northern part of the Gaoligong Shan in western Yunnan Province, China.
