TYPE LOCALITY.— China, Yunnan, Longling County, Longjiang Township, Xiaoheishan Forest
Reserve, N24.83671°/E098.76185°, 2067 m.
DERIVATION OF SPECIES NAME.— The species epithet, xiaoheishan, is a noun in apposition,
derived from the name of the area in which the holotype was collected.
DIAGNOSIS.— Adults of this species (Fig. 9a) can be distinguished from those of all other
species in the region by the following combination of character states: size medium (BL = 5.3 to
5.7 mm), fully-winged, dorsum piceous to reddish brown and distinctly iridescent; head slender,
eyes only moderately projected; clypeus with four setae; mentum and submentum fused, submentum
with six setae; mandibles with two or three small setae along the dorsolateral margin of the
scrobe; pronotum small and narrow (ratio Pw/PL = 1.21), basal angles subrectangular, basal flattened
area restricted; midlateral seta inserted at anterior one-fourth, basolateral seta at hind angle;
elytra with all discal striae evident, deeply impressed and punctate, however striae 1 to 4 effaced
or nearly so near base, parascutellar striole rather long, recurrent stria continuous anteriorly with
stria 5, intervals convex, only a single discal seta (anterior seta) present, inserted at basal oneeighth
of elytra in stria 3; median lobe of aedeagus of male (Fig. 9b) short, with apex bent ventrally
and bluntly pointed, endophallus with a spoon-shaped sclerite.
DESCRIPTION.— Size medium, BL = 5.3 to 5.7 mm. Color of dorsum piceous, shiny, iridescent,
femora concolorous, tibiae, tarsi, antennae and mandibles paler reddish tan, palpi yellowish
tan.
Head. Relatively slender, eyes only moderately projected, but nonetheless convex and with
diameter twice length of tempora. Tempora not or only slightly convex, joined to neck region at ca.
120° angle. Frons slightly flattened, with two pairs of supraorbital setae, frontal furrows linear, distinct
between the eyes, but effaced posterior to insertion of second supraorbital seta. Clypeus with
four setae. Labrum slightly widened apically, apical margin slightly concave. Mandibles sharp, the
right mandible (Fig. 16a) bidentate with the anterior tooth spaced well forward of the posterior
tooth and the left mandible with only a small subtriangular process, also with two or three small
setae along the dorsolateral margin of the scrobe. Mentum and submentum fused. Mentum with
medial tooth rather broad, with the apex either obtuse or truncate, less than one-half as long as lat-
