Type material.

Holotype male: Madagascar, Mahajanga prov., Mahajamba riv., Ampatika env., 17.-19.xi.1995, I. Jeniš lgt. (FGMRI). Paratypes (5): 2 males, 1 female, the same data as holotype; 2 males, Madagascar, Mahajanga prov., Ampatika env., 17.-20.xii.1995, 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. Fully differs by shape of the aedeagus. For differences from other Madagascan species, see key.

Description.

Male (holotype). Elongate-elliptical, transversally convex. Body length 7.0 mm, maximum width 2.9 mm (Figure 4). Ratio length:width of elytra 1.7. Body dark brown; antennae, maxillary and labial palpi and legs lighter. Pubescence white.

Head matt, clypeus shiny, with coarse, dense, umbilicate punctation; distance between punctures approximately the same as their diameter. Pubescence recumbent, long, dense, inclined mostly forwards. Clypeus with shallow transverse depression. Eyes large, globular with long erect sparse pubescence. Frons 2.1 times as wide as diameter of eye, from dorsal view. Antennae consisting of eleven antennomeres, 3rd to 10thpectinate (Figure 22a). 1st antennomere robust, three times as long as wide; 2nd smallest, twice shorter than 1st, as long as wide, almost same width as 1st. 3rd 0.8 times shorter than wide; 4thand 6th to 8th 0.5 times shorter than wide; 9th and 10th 0.6 times shorter than wide and the 10th 0.7 times shorter than wide. Apical antennomere longest, oblong oval, 5 times as long as wide. All antennomeres with short recumbent pubescence, only 1st and 2nd with a few long semi-erect setae. Apical maxillary palpomere long, spindle shaped.

Pronotum convex, matt, transverse (ratio length:width of pronotum 0.7); widest in posterior 2/3. Base of pronotum finely bordered. Middle of pronotum in posterior part with blunt small swelling, posteriorly slightly sharpened. Surface of pronotum with coarse, dense, umbilicate, distance between punctures the same as their diameter. Pubescence short, sparse, recumbent, inclined more or less forwards, in posterior part of pronotum backwards.

Scutellum large, longitudinally rectangular, 1.3 times as long as wide, densely recumbent pubescence, inclined backwards, surface shinning with fine dense puncture.

Elytra oval, transversally convex, shiny, with distinct humeri. Each elytron with fine costae. Surface of elytra irregularly wrinkled, with double punctation - one coarse, dense, umbilicate, punctures almost touching; other is very fine, punctures also almost touching. Pubescence relatively sparse, recumbent, on sides also semi-erect and sporadically also erect, inclined backwards. Posterior margin of each elytron with approximately 25 very small teeth.

Legs stout, with short and dense recumbent pubescence. All tarsi slim, slightly shorter than tibia. 1st metatarsomere as long as 2nd and 3rd together, and same length as 5th. 2nd the same length as 3rd and 4th together. 4th emarginate approximately to ½ of their length. 5th long and robust with two large claws, without teeth.

For aedeagus see Figure 31.

Female. Habitually the same as male, only antennae serrate (Figure 22b). Body length 8.1 mm, maximum width 3.2 mm.

Variability.

Body length 5.4-8.1 mm, maximum width 2.2-3.2 mm.
