DESCRIPTION
Body 5.70­7.83 mm in length, 3.15­4.44 mm in width, from pale brown to black­brown, corium paler; sometimes apical parts of umbones and posterior margin of pronotum slightly lighter than remaining surface of pronotal disc.
Head dorsally impunctate, except for setigerous punctures and several almost indistinct tiny punctures on paraclypei; clypeus without subapical setigerous punctures, each paraclypeus with a row of 4­8 submarginal hair­like setae (Fig. 67); ocular index 2.10­2.80; interocellar index 9.0­15.0; length of antennal segments (in mm): 0.24­0.35: 0.32­0.50: 0.27­0.42: 0.36­0.53: 0.43­0.54.
Pronotum weakly or moderately punctate, calli and posterior fifth of disc impunctate, transverse discal impression behind calli absent or shallow; lateral margins with 9­13 submarginal setigerous punctures (Fig. 66). Anterior convexity of propleuron apically sparsely punctate; depression and posterior convexity densely punctate.
Puncturation of scutellum denser than that of pronotal disc, punctures slightly larger than those on the latter.
Corium distinctly punctate; clavus with one complete and one or two partial rows of punctures; mesocorial disc and exocorium almost evenly punctate; costa entirely separated from exocorium, bearing 4­7 setigerous punctures (Fig. 66).
Hind femora with large subapical tooth on dorsal margin (Fig. 68); male hind tibiae carinate, without denticles (Fig. 68).
Abdominal sterna slightly transversely wrinkled, impunctate or with small punctures posterior to spiracles.
Male genitalia as in Figs 69­72.

DISTRIBUTON
Burma, India, Maldive Islands, Nepal (first record), Sri Lanka.
The occurrence of this species in China (WU, 1935) still remains unconfirmed and seems rather doubtful (LIS 1994a). The records from Japan pertain to Aethus pseudindicus (see LIS 1994a).
