Callimetopus lazarevi sp. n.

( Fig. 4 )

Type material. Holotype: Male , Philippines: Mindanao Isl., Mt. Apo, 10.2013, local collector leg. ( DUBC)

Paratypes: 2 Males, Philippines: Mindanao Isl. , Mt. Apo , 10.2013, local collector leg.; Mindanao Isl. , Kidapawan, Mt. Apo, 06.2014, local collector leg. ( DUBC)

General distribution: Philippines: Mindanao Isl. ( Fig. 3 ).

Description. Body red­brown, with light luster. Surface of body behind middle with two oval dark­brown spots and white strips of pubescence. Length: 16.0­ 17.1 mm, width: 4.9­ 5.0 mm.

Head flat, trapezoidal, with slightly convex eyes. Head between eyes and antennal bases with longitudinal keel, surface along keel with coarse punctation and pubescence. Head widest between eyes. Anterior part of head with brown pubescence and two elongated symmetric spots of yellow pubescence. Cheeks and area around eyes with yellow dense pubescence. Labrum pubescent, with long and dense, yellow­brown setae. Clypeus with transversal impression, matt, with several coarse punctures. Antennomeres brown; 1 st antennomere thickened, with dense yellow­brown pubescence; 3 rd longer than 4 th, with light pubescence.

Pronotum almost cylindrical, expanded laterally before middle, dark brown, pubescent, with acute basal angles, with sparse and coarse punctation. Dorsal disc of pronotum in basal and lateral parts with three longitudinal bands of white pubescence. Scutellum brown, triangular, apically rounded, shiny and pubescent.

Elytra brown, shiny, without metallic luster, slightly flattened and impressed before middle, finely punctate, in basal part with more sparse and coarse punctures. Basis of each elytron concaved at shoulders. Each elytron behind middle with dark brown oval spot and white wavy lines: one line S–shaped or C ­ shaped, beginning from scutellum and almost reaching middle, with fewer pubescence; second white line beginning from shoulders and continues laterally until dark brown spot that encircles (one paratype with interrupted 2 nd line in middle). Along suture located narrow flat elevation, more expressed in apical part. Apex of elytra without sharp projections, straight closer to suture, evenly apically rounded, with many long dark hairs.

Bottom side of body covered with dense pale pubescence and with small sparse brown spots. Femora brown, darkened on apex, with dense yellow­brown pubescence. Tibia brown, slightly darkened in basal part. Tarsomeres brown, covered by yellow­brown pubescence.

Differential diagnosis. The new species is similar to C. ornatus ( Fig. 4 ), but differs from it by the shape of body surface and coloration. Each elytron of new species behind middle with dark brown oval spot and white wavy lines; C. ornatus with three black spots: one of them more small behind shoulder, second in lateral part under shoulders and third large spot is situated behind middle. All spots are more or less rounded with white lines. White lines on elytra of C. ornatus are not connected with each other as at new species. Pronotum of C. ornatus black, new species with dark brown pronotum. Dorsal disc of pronotum of C. ornatus in basal part with well­developed longitudinal spot of white tomentum and with two rudiments of white longitudinal bands in lateral parts; dorsal disc of pronotum of new species with three white longitudional bands.

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