Paratypes: 5 males & 3 females, Philippines: Luzon, Sierra Madre , Quirino , 07.2013, 1 specimen, local collector leg., 08.2013, 4 specimens, local collector leg., 09.2013, 1 specimen, local collector leg.; Nueva Vyscaya, Belance, 08.2013, 1 specimen, local collector leg., Nueva Viscaya, Dupax del Sur, 09.2013, 1 specimen, local collector leg.

Description. Body black, with a light or some specimens with a strong coppery luster. Surface with five circle-shaped spots of green, iridescent scales. Body length: 12.0 – 14.5 mm, largest width: 5.7 – 7.0 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, in frontal part cuspidated, continues to pronotum in basally. Head on front of greenish band covered by pubescence, glossy. Labrum pubescent. Cheeks beneath eyes with transverse band-shaped spot of greenish scales, with fine punctures near eyes. Two basal antennomeres black with green lustre and pubescence, third antennomere brown basally, fourth antennomere testaceous basally, with very fine white pubescence, remaining antennomeres testaceous and tomentose, apical antennomre lightly darkened. Pronotum convex, black, shiny, with coppery luster and very fine punctuation. Dorsal disc of pronotum in frontal part with short spot of greenish scales, lateral parts with large circle-shaped spot of greenish scales, slightly interrupted at top. Lateral disc of pronotum in centrum without pubescence, shiny. Scutellum rounded apically, shiny and tomentose, black or with strong metallic luster. Elytra convex, black, shiny, with light or strong metallic luster, each elytron with five greenish circle-shaped spots of scales, three of which located at dorsal part and two at lateral. Both pairs of dorsal and lateral spots oft are confluent, 8 - shaped. Elytra finely punctate; behind shoulders on both sides without raised nodules, with light impressions under circle-shaped spots; with sparse and coarse punctures and pubescence anteriorly and laterally. Meso-, metaepimera and sternites spotted laterally, covered with greenish scales. Femora with green 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. 6E ).

Differential diagnosis. The new species a little similar to Doliops shavrini Barševskis, 2013 ( Fig. 6F, G ) by body surface shape, but differs from it by complex of characters. Pronotum of D. shavrini Barš. with stripe of pink or greenish scales along lateral pronotal margin and rounded spot at basal margin and each elytron with five pale, pink or greenish spots from which only apical spot circle-shaped, while pronotum of D. jiroux i sp.n. in frontal part with short spot of greenish scales, lateral parts with large circle-shaped spot of greenish scales which in the top are slightly interrupted and each elytron with five green circle-shaped spots.

Mimicry. D. jirouxi sp. n. mimics the weevil Pachyrrhynchus sp. ( Coleoptera : Curculionidae ) ( Fig. 6H ).

Etymology. This species is named after my colleague prominent French cerambycidologist Eric Jiroux in appreci-ation of cooperation.
