TYPE LOCALITY.— China, Yunnan, Fugong County, Shiyueliang Township, 8.5 km above
Shibali on Shibali Road, North Fork of Yamu He, N27.18416°/E98.72026°, 3100 m.
DERIVATION OF SPECIES NAME.— The species epithet, unipilosa, is an adjective derived from
the Latin word, unus, meaning one, and the Greek word, πίλος (transliterated into Latin as pilus),
meaning hair. The name refers to the single discal seta found on the elytra of members of this
species.
DIAGNOSIS.— Adults of this species (Fig. 31a) can be distinguished from those of all other
species in the region by the following combination of character states: size small (BL = 2.7 to 3.1
mm), apterous; body color reddish brown, dorsum shiny, pronotum and elytra slightly iridescent;
eyes small but convex; tempora convex and sparsely pubescent; pronotum transverse (ratio Pw/PL
= 1.42), with basal angles obtuse and rounded; elytra convex, medial striae (1 to 5 or 6) distinct,
finely punctate, more lateral striae more or less effaced; recurrent stria terminated anteriorly on
interval 6; only one discal setiferous pore present, inserted at anterior one-third next to stria 3;
preapical seta present, inserted next to stria 2; median lobe of male aedeagus (Fig. 31b) with apex
slender and rounded, endophallus with a faintly sclerotized scaly area distinctly narrowed distally.
DESCRIPTION.— Size small, BL = 2.7 to 3.1 mm. Body color reddish brown, antennmae concolorous,
legs slightly paler, yellowish brown, palpi paler yellow; dorsum shiny, pronotum and elytra
slightly iridescent, head slightly alutaceous from more deeply impressed, irregularly isodiametric
microsculpture.
Head. Broad; eyes small but convex, their diameter about equal to length of tempora, the latter
short, distinctly convex and sparsely pubescent Frons convex, frontal furrows sharply impressed
and rounded, not attenuated posterior to eyes. Two pairs of supraorbital setae present, the anterior
pair inserted in foveae. Clypeus with four setae. Labrum with six setae, anterior margin distinctly
emarginate. Mentum and submentum not fused. Mentum with medial tooth apically bifid, about
half the length of the lateral lobes. Submentum with six setae anteriorly. Gula broad. Genae with a
single ventral seta one each side. Antennae short, with only about two antennomeres extended posteriorly
beyond basal pronotal margin; antennomeres 2 and 4 about equal in length, antennomere 3
slightly longer.
Pronotum. Transverse (ratio Pw/PL = 1.42), with greatest width at anterior one-third; lateral
margins rounded, slightly more so anteriorly, not or only slightly straighten posteriorly just anterior
to basal angles, the latter obtuse and blunted. Disc convex and smooth, median longitudinal
impression finely impressed, continuous from middle of apical median swelling to posterior margin;
basal foveae small and shallow, faintly impressed; median basal area well defined but short
and transverse, smooth or with a few small longitudinal foveae. Lateral borders slender and finely
relexed dorsally, lateral grooves deeply impressed. Single midlateral setae on each side inserted
near anterior one-third; single basolateral seta on each side, inserted at basal angle.
Elytra. Ovoid only slightly elongate, not or only very slightly more narrowed anteriorly than
posteriorly, humeri distinct but rounded. Disc convex, striae finely punctate, only medial striae 1
to 3 distinctly impressed, more lateral striae more or less effaced, but still evident in most specimens.
Parascutellar striole present, distinct but short. Recurrent stria deeply impressed, its anterior
