Type material.

Holotype male: Madagascar, Antananarivo prov., Manankazo env., 15.-17.xii.1996, I. Jeniš lgt. (FGMRI).

Differential diagnosis.

Differs from other species of this genus from sub-saharan and southern African regions by a lack of elytral costae. Fully differs by shape of the aedeagus. For differences from other Madagascan species, see key.

Description.

Male (holotype). Elongate-elliptical, transversally convex. Body length 3.9 mm, maximum width 1.6 mm (Figure 6). Ratio length:width of elytra 1.7. Body brown, head and pronotum darker, antennae lighter. Pubescence white.

Head shining, with coarse, dense, umbilicate punctated, distance between punctures approximately the same as their diameter. Pubescence recumbent, short, sparse, inclined mostly forwards. Clypeus with shallow transverse depression. Eyes large, globular with very short erect sparse pubescence, almost invisible. Frons 1.3 times as wide as diameter of the eye, from dorsal view. Antennae probably consisting of eleven antennomeres (they are damaged, only 6 antennomeres remain - Figure 24), 3rd to 6thpectinate. 1st antennomere robust, three times as long as wide; 2nd smallest, 3 times shorter than 1st, as long as wide, same width as 1st. 3rd 1.2 times wider as long; 4th 1.3 times wider than long; 5th and 6th 2.2 times wider than long. Other antennomeres are slightly damages or missing. All antennomeres without pubescence. Apical maxillary palpomere short, spindle shaped.

Pronotum convex, matt-shiny, transverse (ratio length:width of pronotum 0.6); widest in middle. Base of pronotum finely bordered. Pronotum without swelling. Surface of pronotum with coarse, dense, umbilicate, distance between punctures smaller than their diameter. Pubescence long, sparse, recumbent, inclined more or less forwards.

Scutellum large, longitudinally almost rectangular, 1.1 times as long as wide, densely recumbent pubescence, inclined backwards, surface shinning with fine dense puncture.

Elytra oval, transversally convex, shining, humeri almost indistinct. Each elytron with only very fine quasi-costae. Surface of elytra with double punctation - one coarse, dense, umbilicate, punctures almost touching; other one is very fine, punctures also almost touching. Pubescence relatively sparse, recumbent, on sides also semi-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, 1.2 as long as tibia. 1st metatarsomere as long as 2nd to 4th together, and same length as 5th. 2nd is same length as 3rd and 4th together. 4th only slightly emarginate. 5th long and slim with long slim claws, without teeth.

For aedeagus see Figure 33.
