( Fig. 2 )

Type material. Holotype: Male, Philippines: Luzon Isl., Nueva Vizcaya, Kasibu , 09.2014, local collector leg. ( DUBC)

General distribution: Philippines: Luzon Isl.

( Fig. 1 ).

Description. Body brown, with light luster and dense pubescence. Length: 15.0 mm, width: 4.9 mm.

Head flat, trapezoidal, widest between eyes, with slightly convex eyes and slightly extended cheeks. Head between eyes and antennal bases with longitudinal keel, surface along keel whith coarse punctation and golden – yellow pubescence. Anterior part of head also with golden ­ yellow pubescence, without pale spots, slightly darkened in basal part. Labrum pubescent, with long dense golden­yellow pubescence. Basal part of labrum shiny, with very sparse pubescence. Clypeus transverse, matt. First antennomere dark, thickened, with dense golden­yellow pubescence and with several small dark brown spots; remaining antennomeres brown; 3 rd antennomere longer than 4 th, with light pubescence.

Pronotum almost cylindrical, expanded laterally before middle, dark brown, pubescent, with acute basal angles and sparse coarse punctation. Dorsal disc of pronotum in basal part with indistinct spot of white tomentum, darkened in frontal part. Scutellum rounded apically, with dense golden­ yellow pubescence.

Elytra brown, glossy, slightly flattened before middle and widely slightly impressed, on both sides with protrunded humps behind shoulders, finely punctate. Basis of elytra concaved at shoulders. Each elytron with two dark brown spots behind middle part. Elytra with grey almost rhomboidal area between spots, here and there with few small dark brown spots. Along suture located narrow flat elevation, more expressed in apical part. Apex of elytra without sharp projections, rounded, with many long dark hairs.

Bottom side of body covered with dense golden ­ yellow pubescence and small brown spots. Legs dark brown, with dense golden tomentum. Tarsomeres brown, covered by golden ­ yellow pubescence.

Differential diagnosis. The new species is similar to C. lazarevi sp. n. ( Fig. 4 ) and C. ornatus ( Fig. 6), but differs from these species by shape of surface and coloration of body. Basal and apical part of elytra of new species with four dark brown spots, with grey almost rhomboidal area between, but by C. lazarevi sp. n and C. ornatus coloration of elytra different. Each elytron of C. lazarevi sp. n behind middle with dark brown oval spot and white wavy lines; C. ornatus with three black spots: one of them more small, located behind shoulder, second spot is located in lateral part of elytra under shoulders, third large spot is located behind middle. All spots are more or less rounded, with white lines. Pronotum of new species pale, darkened in frontal part only; C. ornatus with black pronotum, but pronotum of C. lazarevi sp. n is dark brown.

Etymology. This species is named after my colleague,the famous Russian cerambycidologist Mikhail Danilevsky (Moscow, Russia) in appreciation of cooperation.
