Doliops valainisi sp. n.

( Fig. 3G, M )

Type material. Holotype: Male. Philippines: Mindanao, Bukidnon, 08.2013, local collector leg.) Legs and antennae of holotype damaged; only two antennomeres have been preserved.

Description. Body black, very shiny, with bright coppery luster. Surface with pale, pink scales, arranged in longitudinal lines. Length: 12.0 mm, Width: 4.8 mm.

Head with longitudinal band of pale, pink scales between eyes and antennal bases. Cheeks without spots, only with some sparse pale pink scales. Labrum pubescent. Head with very shiny background, finely punctate, and sometimes with fine microsculpture and pubescence. Antennae black, with bright metallic luster and tomentose. Pronotum convex, black, very shiny, surrounded by a wide band of pale, pink scales. Disc of the pronotum very shiny with sparse punctures. Scutellum rounded and tomentose in apical part. Elytra very convex, black, and very shiny, on each side with five longitudinal rows of pale pink scales. These rows are doubled in the middle of the elytra, as a consequence of which the number of lines seems greater. The first and last rows extended to the elytral apex. The lateral row starts behind the shoulders. Width of elytra at shoulders: 3.8 - 4.6 mm. Greatest width of elytra behind the middle: 5.4 - 6.6 mm. Background of elytra finely punctate. On the elytra, there are longitudinal rows of coarse punctures, basally sparse and pubescent. Meso, meta-epimera and sternites with lateral spots, covered with pale pink scales. Legs of holotype are damaged. Femora without small apical punctures, more or less tomentose and very shiny. Only right foreleg of holotype is undamaged. Surface of the tarsomeres pubescent. Tibia and tarsus apically covered with numerous setae.

Aedeagus ( Fig. 4I ).

Diferential diagnosis. This new species differs from the other species by the characteristic pattern of the body surface. In the genus Doliops Waterh. , there is currently no other known species in which the elytra possess longitudinal lines.

Mimicry. D. valainisi sp. n. mimics the weevil Pachyrrhynchus sp. ( Coleoptera : Curculionidae ) ( Fig. 5K, L ), with which it coexists.

Etymology. This species is named after my colleague and friend, the Latvian carabidologist Uldis Valainis (Daugavpils University, Institute of Systematic Biology, Coleopterological Research Center, Ilgas, Latvia) in appreciation of cooperation.
