Description. Body black, with small, sparse spots and transverse band on elytra of white and yellow-brown pubescence. Length: 20.1 mm, maximal width: 6.0 mm.

Head flattened, wide, somewhat trapezoid, with slightly convex eyes. Dorsal surface of head with irregular coarse punctures and wrinkles, middle portion between eyes and antennal bases with strong, very well visible longitudinal keels, smoothed apically, with very deep impressed longitudinal groove on basal portion of of head. Head covered with sparse, white pubescence. Two white, curved lines stretching from base of antenna toward base of head and merging into impressed groove. Antennal bases thick, slightly extended. Labrum slightly pubescent, shiny, black, with brown anterior part, with widely rounded apical margin. Clypeus brown, transverse, with light luster and with several long, yellow-brown lateral setae. Mandibles massive, wide, shiny, relatively short and sharp, with deep, oval irregular basal depressions and sparse pubescence. Cheeks separated from dorsal portion of head by strong keels, with white, sparse pubescence. Antennae black, covered with very fine and sparse pubescence; basal antennomere black, shiny, wide, rugose, with sparse, white pubescence and with punctures; 2 nd antennomere very short, with white pubescence in inner side; 3 rd an-tennomere slightly longer than 4 th, both with dense, white pubescence on inner side of basal portion; 5 th antennomere black; remaining antennomeres with small spot of white pubescence on inner side of basal portions.

Pronotum black, subcylindrical, slightly flattened dorsally, with irregular spots of white and yellow-brown pubescence, and with very coarse and deep punctation. Anterior ventro-lateral pair of spines very small, indistinct. Basal angles of pronotum small, indistinct, not protruded.. Frontal margin of pronotum almost straight, with widely emarginated lateral sides; basal margin slightly concaved in front of basal angles, with narrow transverse impression. Length of pronotum: 4.4 mm. Width of pronotum: 5.1 mm.

Scutellum small, transverse, widely rounded apically, with visible part withsmall, oval impression. Pars stridens bilobate, with slightly transverse reticulate microsculpture.

Elytra parallel-sided, impressed behind scutellum, black, slightly flattened dorsally, without visible humps behind shoulders, with keel-shaped, narrow, flattened elevation along suture, and with very coarse punctation. Elytra covered with small spots of white pubescence, preapical transverse white band and dense spots of yellow-brown and white pubescence in apical portion. Apex of elytra rounded, covered with numerous long hairs. Length of elytra: 13.6 mm, width of elytra: 6.0 mm. Length of elytra / length of pronotum = 2.26.

Barševskis A.

Ventral surface of body covered with dense, yellow-brown pubescence, especially on margins of sternites and with sparse black dots. Legs black, slightly shiny, covered with white pubescence. Tarsomeres black, covered with black and white pubescence.

Female unknown.

Differential diagnosis. Regarding the shape of the habitus, the new species is somewhat similar to other species from Sulawesi, C. illecebrosus , from which it differs by the following morphological features: 1) elytra with white preapical transverse line (dorsal disc of elytra of C. illecebrosus with wide, white or yellow circle, and with oblique apical band); 2) lateral portions of pronotum without large, wide spots of dense, white or yellow pubescence (lateral portions of pronotum of C. illecebrosus with large, wide spot of dense, white or yellow pubescence); 3) head with very well developed, strong longitudinal keel (dorsal surface of head of C. illecebrosus with fine longitudinal keel).

Etymology. This species is named after my colleague, well-known Latvian entomologist Dmitry Telnov in appreciation of cooperation, and in gratitude for his great contribution to the studies of Coleoptera of the World, especially of the Wallacea Region.
