Description. Female holotype. Measurements (in mm): Total body length—2.58. Head: total length—0.40; length of rostrum—0.19; maximum width of rostrum—0.38; length of eye—0.17; maximum width across eyes—0.64; minimum distance between eyes—0.23. Antenna: length of segments: II—0.11, III—0.09, IV—0.08, V—0.10, VI— 0.0 9, VII—0.07, VIII—0.07, IX—0.13, X—0.11, XI—0.20. Pronotum: maximum length—0.67; width at carina—1.02; minimum width—0.47. Elytra: maximum length—1.56; maximum width—1.09.

Colouration of all body parts generally brown; scape, pedicel and legs pale brown. Funicle dark brown, darker than scape and pedicel, antennomeres VII-VIII almost black, antennal club completely black. Distal part of tibiae dark brown to blackish. Pronotum and elytra with almost regular spots of whitish pubescence.

Vestiture. Head with sparse whitish appressed setae ( Fig. 3 ). Antennae with pubescence, scape and pedicel covered by whitish suberect setae, antennomeres III-VIII with sparse black suberect setae, antennal club with black appressed setae. Pronotum with whitish setae formed to regular spots. Elytra also covered with whitish setae, each elytron with two indistinct spots in sutural part, four spots on the second elytral interval and six spots on sixth elytral interval. Apical margin of elytra with whitish edge. Legs including tarsomeres covered with dense, fine whitish decumbent setae. Venter of thorax and abdominal sternites with dense whitish pubescence. Pygidium covered with sparse whitish appressed setae.

Structure. Head. Rostrum weakly convex, anterior part with fine sculpture. Frons without narrow longitudinal carina in the middle. Eyes large, not emarginate, ocular index 1.12. Ratio of maximum width across eyes to the maximum width of rostrum 1.68. Antennae slightly longer than head and pronotum together. Funicle thin, club moderately robust. Pronotum ( Fig. 1 ) transverse (ratio of its length to its width at carina 0.66), gradually narrowed anteriorly, disc convex in middle ( Fig. 2 ). Dorsal transverse carina slightly curved. Postero-lateral edges of pronotum obtuse-angular. Posterior margin conspicuously convex, fitting in concavity on base of elytra. Elytra oval, slightly narrowed posteriorly. Ratio of maximum length of elytra to maximum width 1.43. Anterior margin of elytra concave ( Fig. 1 ), corresponding with the convexity of posterior margin of pronotum. Surface of elytra deeply striate, width of each stria distinctly narrower than width of elytral interval.

Male. Unknown.

Differential diagnosis. The new species differs from all other species of the genus in its different colour pattern and characters given in the key.

Etymology. Patronym, dedicated to our friend Mr. Cedric Ralaison Nalintsoa, a member of our Czech-Madagascan expeditions in 2011, 2013, 2014 and 2015.

Habitat. All three specimens of the type series were collected by beating dead branches of an unidentified species of deciduous tree. The branches were at a height of ca 2-4 m above ground level and had a diameter of 2 to 3 cm. The dead twigs were estimated to be no older than one year, and were still covered with an intact bark layer. The tree was situated in a slightly sunny place at the edge of a forest path, in the primary forest with visible mining activities. The type locality of this species is shown in Fig. 4 .

Distribution. North Madagascar ( Fig. 5).
