Diaprepes abbreviatus

Male. Length 1.28–2.66 mm (rostrum/pronotum length ratio 0.57–0.67, rostrum length/width ratio 1.32–1.48). Body oval to elongate, length/width ratio 2.50–2.83. Head with dorsal margin surrounding each eye with two to three rows of appressed whitish scales; frons with median carina extending from frontal fovea to anterior region of occiput. Eyes separated from anterolateral margin of pronotum by nearly 10 rows of scales; interocular distance distinctly shorter than maximum width of eye. Rostrum dorsally subplane, with transverse, slightly angulate carina along posterior edge of epistoma, median line carinate, with two dorsolateral carinae. Antennae with funicular antennomeres progressing from elongate to equilateral; club similar in length to funicular antennomeres III–VI, nearly three times longer than wide. Pronotum equilateral to trapezoidal, length/width ratio 0.88–0.98, pronotum/elytra length ratio 0.31–0.33; in lateral view subquadrate to conical, with foveate to longitudinal impressions above procoxal cavities. Scutellum subcircular, glabrous, margins finely setose. Elytra with intervals subplane to strongly convex; intervals of mesal margin/I and VIII/IX elevated, glabrous along anterior three-quarters; lateral margins subparallel along most of length, anterior one-sixth slightly expanded (alate). Wings with wing/body length ratio 1.12–1.15, wing length/width ratio 3.42–3.48. Legs with mucro shorter than tarsal claw; mesotibia slightly shorter than metatibia, slightly arcuate. Venter with sterna III and IV centrally subplane, laterally slightly convex. Pale whitish to yellowish scales arranged in distinct patch- or stripe-like pattern on head, pronotum, prosterna, elytra, and ventral sterna. Scale colour varies from white to various shades of yellow to rusty brown or nearly orange, or with limited pinkish regions.
