Type material.

Holotype male: Madagascar, Toliara prov., Toliara env., 23.-27.xi.1996, J. Stolarczyk lgt. (FGMRI).

Differential diagnosis.

This species is similar to C. (C.) humeralis Pic, 1926, but differs by the lighter colour of the elytra and missing lighter humeri. Fully differs by shape of the aedeagus. For differences from other Madagascan species, see key.

Description.

Male (holotype). Elongate-elliptical, transversally convex. Body length 6.6 mm, maximum width 2.5 mm (Figure 9). Ratio length:width of elytra 1.5. Body brown, pronotum darker; antennae, maxillary and labial palpi and legs lighter. Pubescence yellowish white.

Head matt-shiny, with double punctation - one coarse, dense, umbilicate, distance between punctures approximately the same as their diameter; other one is very fine, almost invisible, punctures almost touching. Pubescence semi-erect, long, in anterior part inclined forwards, in posterior part inclined more or less backwards. Clypeus with shallow transverse depression, shiny. Eyes large, globular with long erect dense pubescence. Frons 2.7 times as wide as diameter of the eye, from dorsal view. Antennae consisting of eleven antennomeres, 4th to 10th pectinate (Figure 27). 1st antennomere robust, 2.5 times as long as wide; 2nd smallest, almost triangular, only one-half long as the 1st, as long as wide, slightly narrower as the 1st. The 3rd strongly serrate, as long as wide, 1.8 times as width of 1st. 4th to 9th 1.4 times as wide as long; 10th 0.9 times shorter as long. Apical antennomere is longest, oblong oval, 5.7 times as long as wide. All antennomeres on margin with short erect dense setae. Apical maxillary palpomere long, spindle shaped.

Pronotum convex, matt-shiny, rounded, transverse (ratio length:width of pronotum 0.8); widest at 2/3 posteriorly. Base of pronotum finely bordered. Middle of pronotum at base with blunt small swelling, posteriorly slightly sharpened. Surface of pronotum with double punctation - one coarse, dense, umbilicate; distance between punctures approximately one half of their diameter, some punctures almost touching; other one is very fine, punctures almost touching. Pubescence long, dense, semi-erect, inclined more or less to middle of pronotum, only on sides inclined to margin.

Scutellum triangular with blunt top, narrow, 1.8 times as long as wide, very sparse and short recumbent pubescence, inclined backwards.

Elytra oval, transversally convex, shiny, with distinct humeri. Each elytron with five fine costae, almost invisible, but apex more distinct. Surface of elytra with double punctation, one coarse, dense, umbilicate, distance between punctures approximately the same as their diameter; other one is very fine, punctures almost touching. Pubescence relatively sparse, recumbent partly also semi-erect, inclined backwards. Posterior margin of each elytron with approximately 25 small teeth.

Legs stout, with short and dense recumbent pubescence. All tarsi robust, same length as tibia. 1st metatarsomere as long as 2nd and 3rd together, same width, slightly emarginate on top. 4th slightly shorter than previous, more emarginate, almost to 2/3 of their length. 5th is same length as 3rd and 4th together, rectangular, wider on the top, with two large claws, without teeth.

For aedeagus see Figure 35.
