Exophthalmus

Length 1.52–3.54 mm. Body oval to elongate, length/width ratio 2.52–2.67. Rostrum rectangular in dorsal outline, dorsolateral margins subparallel, slightly widened at antennal insertion, anteriorly carinate, posteriorly convex; rostrum length/width ratio 1.19–1.39. Pronotum equilateral to transverse, length/width ratio 0.79–0.89; in lateral view subquadrate to conical, with one irregular impression above procoxal cavity. Elytra with greatest width at humeri or near central region; lateral margins subparallel along most of length, anterior one-sixth slightly expanded; punctures narrowly separated; intervals subplane, intervals I–III more widely spaced than intervals IV–X. Scales with multiple colours variously interspersed, typically darker (brownish) dorsally on head, pronotum, and elytra, lighter (white to reddish brown) laterally, ventrally, and on legs. Setae irregularly arranged, sparse to dense, appressed to recurvate, white to reddish brown. Antennae with scape extending to posterior margin of eye; funicular antennomeres progressing from elongate to equilateral, from clavate to cylindrical; club nearly three times longer than wide, dark brown. Eyes separated from anterolateral margin of pronotum by distance similar to horizontal diameter of eye. Wings with wing/body length ratio 1.14–1.22.
