TYPE LOCALITY.— China, Yunnan, Fugong County, Shiyueliang Township, 0.2 km w of Shibali, N27.16650°/E098.77936°, 2537 m, DERIVATION OF SPECIES NAME.— The species epithet, unisetulosa, is an adjective derived from the Latin words, unus, meaning one, and setulosus, meaning bearing bristles or setae. The name refers to the single discal seta found on the elytra of members of this species. DIAGNOSIS.— Adults of this species (Fig. 29a) can be distinguished from those of all other species in the region by the following combination of character states: size small to medium (BL = 3.3 to 3.5 mm), apterous; body color dark reddish brown, dorsum shiny, very slightly iridescent; eyes small, only slightly projected laterally; tempora convex and sparsely pubescent; pronotum transverse (ratio Pw/PL = 1.40), with basal angles obtuse and rounded; elytra convex, with medial three or four stria distinct, finely punctate, more lateral striae more or less effaced; recurrent stria terminated anteriorly in presumed location of interval 6; only one discal setiferous pore present, inserted near anterior one-third next to stria 3; preapical seta present, inserted next to stria 2; median lobe of male aedeagus (Fig. 29b) with apex lobated and broadly rounded; endophallus with a large, scaly sclerorized area. DESCRIPTION.— Size small to medium, BL = 3.3 to 3.5 mm. Body color dark reddish brown, interval 1 of elytra slightly paler, reddish, appendages yellowish brown, palpi paler yellow; dorsum smooth, pronotum and elytra shiny, very slightly iridescent, head slightly alutaceous from more deeply impressed isodiametric microsculpture. Head. Rather broad; eyes small, only slightly projected laterally, their diameter about equal to length of tempora, the latter convex and sparsely pubescent. Frons convex, with frontal furrows evenly rounded and deeply impressed, continuous to posterior margins of tempora. 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 broad and apically bifid, less than 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 1.5 antennomeres extended posteriorly beyond basal pronotal margin; antennomeres 2 and 4 about equal in length, antennomere 3 slightly longer. Pronotum. Transverse (ratio Pw/PL = 1.40), with greatest width near anterior one-third, moderately narrowed posteriorly; lateral margins rounded, slightly more so anteriorly, slightly straighten, but not at all sinuate, just anterior to basal angles, the latter bluntly obtuse. Disc convex, median longitudinal impression finely impressed, continuous from posterior side of apical median swelling to posterior margin; basal foveae shallow, faintly impressed; median basal area well defined but short and transverse. 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.
