( Fig. 2A, B )

Type material. Holotype: Male. Philippines: Luzon, Sierra Madre , Quirino, 2014, local collector leg.

Paratypes: Male and 5 females: Philippines: Luzon, Sierra Madre , Quirino, 08.2011, local collector leg., 10.2013, 2 specim., local collector leg. 11.2013, local collector leg., 04.2014, local collector; Isabela, 09.2013, local collector leg.

Description. Body black, with strong metallic luster. Surface of elytra with three big, greenish, iridescent circle-shaped spots. Body length: 11.9 – 14.2 mm, largest width: 4.8 – 6.0 mm.

Head almost square, parallel-sided, with bilobate eyes. Head between eyes and antennal bases with longitudinal band of greenish scales and thin, straight median line without scales. Longitudinal band long, pointed frontally. On front of greenish band head covered by very fine pubescence and punctuation. Cheeks beneath eyes with large transverse spot of greenish scales or without it, with some punctures near eyes and with fine transverse microsculpture. Labrum pubescent and punctate. Head finely punctate, glossy, with strong metallic luster; weakly convex frontally, with very fine punctuation. First antennomere glossy, with metallic luster, second antennomere black and with light luster, third antennomere dark broun basally, black and widened apically, remaining antennomeres are testaceous and tomentose. Pronotum convex, shiny, with sparse coarse punctuation laterally and with very fine microsculpture. Dorsal disc of pronotum in middle of frontal part with short rudimental spot of greenish scales, with large semicircle-shaped spot of greenish scales laterally. Disc of pronotum in centrum without pubescence, shiny, with very fine punctuation. Scutellum rounded apically, shiny and tomentose. Elytra convex, shiny, with strong metallic luster and with three circle-shaped spots of greenish or yellow scales. Circles sometimes confluent, with wider bands than that at D. pachyrrhynchoides Heller, 1916 . Elytra finely punctate; on sides with lightly protrunding shoulder bumps. Elytra behind shoulders on both sides with wide raised nodules and impressions; with sparse an d coar se pun ctur es an d pubescence anteriorly and laterally. Width of elytra at shoulders: 4.5 – 5.4 mm. Largest width of elytra behind middle: 4.8 – 6.0 mm. Meso-, metaepimera and sternites spotted laterally, covered with greenish scales. Femora with small greenish or yellow spot at apex and more or less tomentose. Dorsal surface of tarsomeres covered by grey, tomentum. Tibia and tarsi in apical part covered by numerous setae.

Differential diagnosis. The new species is similar to D. pachyrrhynchoides and D. ligata Schwarzer, 1929 . All tree these species are with tree big circle shaped spots on elytra. Shape of these spots are specific for every species. Different also shape of pronotum and colour of body ( Fig. 2A, B, C, D ).

Mimicry. D. balalaikinsi sp. n. mimics the weevil Pachyrrhynchus cf. reticulatus ( Coleoptera : Curculionidae ) ( Fig. 2E ).

Etymology. This species is named after my colleague, Latvian coleopterologist Maksims Balalaikins (Daugavpils University, Daugavpils, Latvia) in appreci-ation of cooperation.
