DIAGNOSIS.— Adults of this subgenus (Figs. 12a, 13a) can be recognized by the following<br />
combination of character states: size moderate (BL = 3.5 to 4.8 mm), apterous, body dark, reddish<br />
brown to piceous, surface micaceous; pronotum with basal angles prolonged posteriorly as slender<br />
digitiform processes, with two setae (midlateral and basolateral) present on each side; elytra<br />
markedly convex, inflated, slightly tear-shaped, humeri effaced, elytral discal striae effaced, with<br />
two (in most members) or three (in a few members) discal setae present, aligned on interval 3 near<br />
stria 3, preapical seta absent from most members.<br />
GEOGRAPHICAL DISTRIBUTION.— Same as for genus (see above).<br />
Key for Identification of Adults of Subgenus Queinnectrechus species<br />
of the Gaoligong Shan Region<br />
1. Size larger (BL = 4.3 to 4.8 mm), elytra (Fig. 12a) more elongate; median lobe of male aedeagus<br />
broadest at mid-shaft, with apex long and recurved. . . . . . . . . . . . . Q. griswoldi sp. nov.<br />
Size smaller (BL = 3.5 to 3.8 mm), elytra (Fig. 13a) shorter, ovoid; median lobe of male aedeagus<br />
