Habitus as in Figs. 113–114 ; body length of holotype 6.6 mm , of paratype 7.2 mm . Body dark brown; head, pronotum and elytra brown, head and pronotum darker with feeble metallic reflections; labrum and palpi reddish; antennae reddish at base, darkened starting from antennomere IV ( holotype ) or antennomere V ( paratype ); mandibles black; legs dark brown. Frons weakly convex, feebly impressed in middle, with confused and close punctures and relatively long silvery pubescence; punctation confluent near clypeus; clypeus almost flat in holotype , feebly convex in paratype , and with punctation as strong as on frons. Antennomere I one fourth longer than antennomere II and more than twice as wide; antennomere II 2.5 times longer than wide, feebly bent; antennomere III one third longer than II; antennomeres IV and V nearly as long as antennomere III and longer than VI; antennomeres VII–X feebly widened, VII a little longer than the following ones; antennomere XI nearly three times longer than wide. Pronotum 1.6 times wider than long (2.9 × 1.8 mm in holotype ), at base only little wider than at distal border; sides regularly arched and margined throughout, widest in midlength; surface strongly and densely punctate; punctures close to each other but not confluent, surface between punctures smooth and bright; pubescence long, fine, silvery, suberect on disc, erect on sides. Scutellum a little wider than long, rounded distally (Fig. 28), pubescent. Hypomeron punctured throughout, with moderately long pubescence; prosternum with long pubescence; mesepimera bare, not punctured; metanepisterna three times longer than wide, pubescent. Elytra oblong, 1.4 times longer than wide at humeri (4.6 × 3.3 mm in holotype ), feebly impressed in basal fifth; sides subparallel in basal half, then regularly curved to apices, which form right angle; humeri weakly prominent; punctation finer than on pronotum, irregular, finer on apical slope; pubescence long, on elytral sides clearly longer than on pronotal sides, fine, erect. Epipleura gradually tapering to rear, reaching elytral apices. Legs moderately long; femora unarmed, moderately swollen; protibiae feebly bent, meso– and metatibiae nearly straight; pro- and mesotarsomere I poorly widened. Claws bifid starting from their midlength, with short internal tooth. Abdomen dorsally poorly sclerotized, with exception of last visible segment. Aedeagus as in Figs. 24–25. Female unknown. Differential diagnosis. Colasposoma ( Falsonerissus ) villosum is related to C . ( F .) grande and C. ( F. ) distinguendum sp. nov. , and characterized by very long dorsal pubescence and different shape of median lobe of aedeagus. Etymology. The name villosum (hairy) refers to the relatively long setae covering the dorsum in this species.
