TYPE LOCALITY.— China, Yunnan, Gongshan County, Bingzhongluo Township, Sw slope of
Kawakarpu Shan, on slope NE of Chukuai Lake, N27.98206/E098.48027°, 3950 m.
DERIVATION OF SPECIES NAME.— The species epithet, gongshanicus, is derived from the name
of the county (Xian) in which the holotype was collected, Gongshan, and the Latin adjectival suffix,
-icus, meaning belonging to or pertaining to.
DIAGNOSIS.— Adults of this species (Fig. 13a) can be distinguished from those of all other
species in the region by the following combination of character states: same features as members
of Q.griswoldi except, size smaller (BL = 3.5 to 3.8 mm), body form short, with elytra, in particular,
shorter and more oval, less elongate; digitiform projections of pronotal basal angles slightly
more divergent laterally; elytral recurrent stria slightly deeper impressed, median lobe of male
aedeagus (Fig. 13b) markedly different, with shaft thin and straighter, abruptly bent basally, apex
short and rectangular, endophallus with a single apically acuminate internal sclerite.
DESCRIPTION.— Size smaller, BL = 3.5-3.8 mm. Body color dark, reddish-piceous, antennae
and legs reddish tan, palpi and tarsi paler, yellowish tan.
Head. Moderate in size; eyes small and convex, their convexity greater than and their diameter
about as long as tempora, the latter moderately convex and glabrous. Frons not flattened; frontal
furrows deep, rounded, slightly attenuated posterior to the eyes. Clypeus with four setae. Labrum
with six setae, anterior margin distinctly concave. Mentum and submentum fused. Mentum with
medial tooth short, wide, bifid, less than one-half the length of the lateral lobes. Submentum with
six setae anteriorly. Gula wide. Genae with a single seta ventrally on each side. Antennae slightly
shorter, with only two antennomeres extended posteriorly beyond basal pronotal margin, antennomeres
slightly broadened, antennomere 3 slightly longer than antennomeres 2 or 4.
Pronotum. Cordate (ratio Pw/PL = 1.15), markedly narrowed posteriorly, greatest width near
anterior one-third, lateral margins rounded anteriorly, then straightened posteriorly just anterior to
basal angles, the latter prolonged as slender, slightly divergent digitiform processes. Disc marked-
