Hymetes Lacordaire

( Figs. 1 H ; 2 G ; 3 G ; 4 G ; 5 G )

Hymetes Lacordaire, 1848: 861 ; Type species: Hymetes javana Lacordaire, 1848 , by monotypy; Baly, 1865: 61 (description)

Diagnosis. Length 6.34-7.10 mm, width 4.27-4.46 mm. General body shape subquadrate. Antenna serrate beyond 5 th antennomere, 2 nd antennomere globular, 3 rd, 4 th and 5 th antennomere of equal size, subcylindrical, 6 th antennomere very short. Pronotum medially elevated, without pronounced tubercules, but with relatively short, acute ridges. Pronotal base opposite mesoscutellum (posterior pronotal lobe) with acute notch. Prosternal process approximately ½ length of entire prosternum, narrow, slightly broadening posteriorly. Anterior margin of metasternum forming an elongate projection. Mesoscutellum trapezoidal. Metascutellum not exposed. Sutural serra- tion of elytra complete. Elytral tubercules weakly developed. Tibiae slightly curved, flattened dorsally, with sharp edge dorsomedially. Fore- and midtibial apices without spine. Tarsal claw appendiculate.

Distribution. Oriental Region ( Monrós 1952).

Remarks. This genus can be separated from all other chlamisine genera by the anteriorly elongate metasternum projection (concave in other chlamisines), by the subcylindrical 3 rd, 4 th and 5 th antennomeres, and by the absence of spines on the fore- and midtibiae.

Three species are known from India and Java ( Monrós 1952).
