Therates barsevskisi sp. n.

( Figs. 1–2 )

Type material: Holotype, male – “ Philippines | W Visayas, Antique | Panay 2018. VII | local collector leg” ( DUBC) . Paratypes: 1 female – “ Philippines | Panay isl. | Antique VII. 2017 ” (cJW) ; 1 male, 1 female – “ Philippines, W.Visayas, Panay island , M. Madia­as, VI.2018 ” (cRS) .

Diagnosis. This new species belongs to “ fasciatus ” – group, characterized by clypeus without setae, and by elytra without tumescence at mid length. By its elytral pattern it is similar to T. pseudosemperi (Mindoro isl.) and T. negrosicola (Negros isl.), but this new species can be easily distinguished by its entirely black pronotum.

Description. Body length 11.0­ 11.5 mm, mean = 11.1.

Head and pronotum black with light gold luster; elytra black with gold luster and orange transverse bands. Labrum, mouth parts and legs orange.

Head without microsculpture, temples not protruding, slightly convergent towards pronotum; clypeus without setae; frons wide, frontal grooves shallow, gradually curved; eyes very protruding; each supra­orbital plate with one seta. Labrum

( Figs. 6–7 ) relatively long; with extremely shallow microsculpture, almost isodiametric on the disc and slightly transverse on sides; with nine sub marginal setae and ten teeth: with six short frontal central teeth’s, with rounded apices in four central and slightly pointed in lateral ones, as well as a pair of slightly longer and narrower latero­apical teeth and longer and pointed latero­basal teeth on both sides. Mandibles orange with dark brown tooth’s. Antennae relatively long; blackish brown, scape and pedicel yellow, except blackish dorsal side.

Pronotum as long as wide, smooth; midline barely visible; anterior and posterior grooves glabrous. Aedeagus ( Fig. 8 ) relatively large; with a wide, gradually curved basal bulb; ventral side of median lobe straight; apical third moderately downturned, apex relatively wide and rounded; internal sack with big and thick flagellum, hookshaped at the base.

Distribution. Philippines, Panay island.

Etymology. Species is named after our friend and colleague Dr. Arvids Bar š evskis, a coleopterist in Daugavpils University ( Latvia) in appreciation of his contribution to the study of coleopterofauna of Philippines.
