Doliops savenkovi sp. n.

( Figs. 3B, J )

Type material. Holotype: Male. Philippines: N Luzon, Sierra Madre, Quirino, 10.2013, local collector leg.

Description. Body black, shiny, without metallic luster. Surface with spots of green and pink scales. Length: 12.0 mm, width: 5.0 mm.

Head narrow, with longitudinal band of pale pink and greenish scales between eyes and antennal bases. Cheeks with small, greenish spots. Labrum covered with numerous setae. Head black, finely punctate and shiny. Three basal segments of antennae black, shiny and pubescent, with slight metallic luster. Fourth antennomere testaceous, in basal part with white pubescence. The remaining antennomeres testaceous and tomentose. Pronotum convex, black, shiny, with greenish and pink scales on both lateral and anterior margin. Dorsal disc of pronotum smooth, without scales, slightly tomentose laterally. Pronotum emarginated with narrow line of pink, iridescent scales. Scutellum rounded, apically tomentose. Elytra convex, black, shiny, with transverse, wide, bandformig spots. Two small elongated spots located basally on both sides of scutellum. Remaining three transverse, bandforming spots wide, green, emarginated with narrow linear pink scales. Between these spots there are black, smooth transverse areas, which converge with a black longitudinal band along the elytral suture. Elytra behind shoulders with raised nodules. Width of elytra at shoulders: 4.7 mm. Largest width of elytra behind tmiddle: 5.0 mm. Elytra finely punctate. Anteriorly with sparse and coarse punctuation and pubescence. Meso-, metaepimera and sternites with spots at their sides. Legs short, thick. Femora with greenish spot at apex and more or less tomentose. Surface of tarsomeres covered with grey pubescence. Tibia and tarsi apically covered with numerous setae.

Differential diagnosis. This new species differs from the other ones by the characteristic pattern of the body surface. The new species is slightly similar to D. sklodowskii sp. n. ( Fig. 3D, K ) and D. metallica Breuning, 1938 ( Fig. 3C ), however, differing by the shape of the disc of the pronotum, by the shape of the prescutellar spots on the elytra and the shape of genitalia ( Fig. 4B, D, F ,).

Mimicry. Currently we have no data about the mimicry of this species. The new species is a somewhat similar to D. sklodowskii sp. n. ( Fig. 3D, K ) and D. metallica Breuning, 1938 ( Fig. 3C ), which mimic Pachyrrhynchus orbifer Waterhouse, 1841 ( Coleoptera : Curculionidae ) ( Fig. 5A,B,C,D ).

Etymology. This species is named after my colleague and friend, the Latvian entomologist Nikolay Savenkov (Latvian Museum of Natural History, Riga, Latvia), in appreciation of cooperation.
