Distribution. Philippines: Luzon Island.

Description. Body black, with metallic luster. Elytra with small spots of pink scales, variable in color and drawing shape. Body length: 10.6–10.8 mm, largest width: 4.5–4.8 mm.

Head almost square, somewhat parallel-sided, with large, but not strongly extended, bilobate eyes. Anterior portion of head between eyes and antennal bases with impressed longitudinal band of pale pink scales, and thin, straight median line. Frontal part of head behind of clypeus convex, glossy, with impressed longitudinal line, delicate punctation and pubescence. Longitudinal band of pink scales in holotype starting from basal part of head and extending to anterior margin of eyes; this band is truncated in paratype and starting between antennal bases. Posterior portion of head with golden shiny. Cheeks under eyes with very small rudimental spot (holotype) or without spot of pink scales (paratype). Lateral portions of mandibles and genae with four to five long, black setae. Labrum convex, glossy, with concaved apical margin, with pubescence, small punctures, and covered with long setae. Clypeus short, shiny, transverse. Head with very fine microsculpture, punctation and fine tomentum (except of metallic shiny basal portion of head). Basal area of antennae weakly protruding. Antennae long and slender, with short pubescence and a brush of inner setae at apex of antennomere 3, and with some long setae at remaining antennal segments, except of four apical antennomeres; antennomeres 1 and 2 with strong metallic luster and very fine pubescence; antennomere 3 black, with dark-brown basal portion, widened apically; antennomere 4 testaceous basally and darkened apically, with very fine pubescence; remaining antennomeres testaceous and tomentose.

Pronotum very convex, subcylindrical, wider than long, anterior border prominent, posterior bor- der double, sinuous, disc anteriorly bulging; black (holotype) or metallic golden (paratype), shiny, with fine microsculpture and very fine punctation in holotype or with fine punctation in paratype. Disc of pronotum glossy, shiny. Lateral margins of pronotum with band of pink scales; posterior portion of pronotum with small rudimental spots (holotype); paratype with only aedeagus

two small rudimental spots in lateral margins of pronotum.

Scutellum widely rounded apically, shiny and tomentose, black. Pars stridens not visible.

Elytra convex, black, with metallic luster and spots of pink scales. Each elytron of holotype with curved hook-shaped spot in basal portion; each elytron of paratype with small rudiment of this basal spot, behind which elytra with some small irregular spots of pink scales. Lateral sides of elytra with somewhat protruding shoulders. Width of elytra at shoulders: 4.0– 4.5 mm. Largest width of elytra behind middle: 4.5–4.8 mm. Elytra with very fine microsculpture and very fine sparse punctures, with sparse and coarse punctures and pubescence in anterior portion. Meso-, metaepimera and sternites spotted laterally, covered with pink scales. Legs short and robust. Femora strongly widened at apical third, shiny, with strong, golden metallic luster, and with small elongate pink spot at apex, more or less pubescent. Tibia flattened at external border, with fringe of dark setae. Dorsal surface of tarsomeres covered by pale pubescence with blue luster. Apical portions of tibia and tarsi covered by row of numerous yellow setae.

Male. Aedeagus (Fig. 1D) arched, with upwarded sharp apex. Aedeagus is located obliquely within abdomen, with apex rotated down.

Differential diagnosis. Regarding the general shape of the body and somewhat similar coloration, the new species is related to D. elcanoi Vives, 2011 ( Fig. 2 ), known also from Luzon island. It can be distinguished from this species by the following characters: 1) basal part of head with golden luster, while that in D. elcanoi with black or greenish luster; 2) each elytron behind basal hook-shaped spot with some small irregular pink spots, while that in D. elcanoi with)(- shaped transverse bands; 3) basal portion of femora with more smaller and more rounded scale spot than that in D. elcanoi .

Etymology. Patronymic, the species is named after Mari Felipe ( Philippines: Calumpit), who kindly donated type specimens for this study.
