Genus Anisoderomorpha Arrow, 1925

Anisoderomorpha Arrow 1925: 167 , 182–183; Villiers 1945: 186.

Type species: Anisoderomorpha tuberculata Arrow, 1925 .

Diganosis. This genus resembles the genus Celolanguria Arrow, 1925 from South India but can be distinguished by the following characters: pronotum with a pair of small foveae at basal area (with long and deep foveae in Celolanguria ), tibiae straight (curved in Celolanguria ), elytra parallel-sided (tapering in Celolanguria ).

Redescription. Body cylindrical, parallel-sided. Head finely and sparsely punctured, symmetrical in male but asymmetrical in A. tamdaoensis sp. nov. female. Eyes not large, finely faceted. Frons with a deep longitudinal ocular stria. Mandibles strong, bifid at apex. Antenna not reaching basal margin of pronotum, with 5-segmented club. Pronotum irregularly and finely punctured, convex in front, with a pair of small foveae divergent anteriorly at basal area; anterior margin almost straight; lateral side distinctly marginate; basal margin distinctly marginate, arched posteriorly at median part; anterior angles not projected. Scutellar shield pentagonal. Elytra parallel-sided, deeply striated and punctured; humeri ( Figs. 9 , 21 , 36 , 50 ) prominent, each with a strong erect tubercle dorsally in both sexes; apex rounded or truncated with a spine at the outer angle. Legs fairly stout, not long; femora smooth. Abdominal ventrite 1 not bearing coxal lines. Caudal margin of ventrite 5 ( Figs. 10 , 22 , 37 , 52 ) arcuate, densely pubescent and punctate.

Distribution. Malaysia, Myanmar, Vietnam.

Biology. Unknown.
