Doliops daugavpilsi sp. n.

( Fig. 3A, B, C )

Type material. Holotype: Male. Philippines: Mindanao, Mt. Apo , Davao del Sur, 12.2013, local collector leg.

Paratype: Female. Philippines: Mindanao, Mt. Apo , Davao del Sur, 04.2014, local collector leg .

Description. Body black, with a thin (holotype) or very strong golden (paratype) luster. Surface with yellow, iridescent circle-shaped spots. Body length:12.7 - 13.0 mm, largest width: 5.5 - 5.7 mm.

Head almost square, parallel-sided, with bilobate eyes. Head between eyes and antennal bases with longitudinal band of yellow scales and thin, straight median line without scales. Longitudinal band long, in frontal part start with small white scales, in basal part interrupted (holotype) or continuously wide (paratype). On front of yellow band head covered by white pubescence. Cheeks beneath eyes with large spot of yellow scales, with some punctures near eyes and with fine transverse microsculpture. Labrum pubescent and punctate. Head black, finely punctate, glossy, with light or strong golden luster. In frontal part weakly convex, with punctuation. Two basal antennomeres black with light luster (holotype) or first antennomere with strong golden luster and second antennomere black (paratype). First two basal antennomeres with pubescence, third antennomere brown basally, fourth antennomere testaceous basally, with very fine white pubescence; remaining antennomeres testaceous and tomentose. Pronotum convex, black, shiny, with sparse coarse punctuation and with fine transverse microsculpture. Dorsal disc of pronotum in frontal part with short fine longitudinal stripe of yellow scales, lateral parts with large circle-shaped spot of yellow scales. Disc of pronotum in centrum of basal part without pubescence, shiny. Scutellum rounded apically, shiny and tomentose. Elytra convex, black, shiny, without metallic luster (holotype) or with strong golden luster (paratype), with yellow circle-shaped spots of scales. Basal yellow circle elongated, similar as that of D. villalobosi Heller, 1926 ( Fig. 3D ). Second spot transverse, lightly 8 – shaped, in dorsal and lateral parts connected with basal spot. Third apical spot lightly triangular, connected with previous transversal spot laterally. Elytra on side with slightly protruding shoulder bumps. Elytra finely punctate; behind shoulders on both sides without raised nodules and impressions; with sparse and coarse punctures and pubescence anteriorly and laterally. Width of elytra at shoulders: 5.1 mm. The largest width of elytra is behind the middle: 5.7 mm. Meso-, metaepimera and sternites spotted laterally, covered by yellow scales. Femora with small 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.

Aedeagus ( Fig. 3C ).

Differential diagnosis. The new species differs from other species of the genus Doliops Waterh. by shape of surface.

Mimicry. D. daugavpilsi sp. n. mimics the weevil Pachyrrhynchus sp. ( Coleoptera : Curculionidae ) ( Fig. 3E ).

Etymology. The name daugavpilsi dedicated to the second largest city of Latvia – Daugavpils (www.daugavpils.lv), where located Daugavpils University (www.du.lv), one of the most important Coleopterological research center of Eastern Europe.
