( Fig. 1 )

Type material. Holotype: Female. INDONESIA: Waigeo Isl., / Wasai vill., 02.2019. / V. Voitsekhovski leg. [handwrited on white label]; HOLOTYPUS: Pseudodoliops / veigeli / voitsekhovskii sp. nov. / A.Barševskis descr. 2020 [handwrited on red label] ( DUBC).

General distribution: Indonesia: Mollucas, Waigeo Island.

Description. Body length: 10.9 mm, body width: 3.3 mm. Dorsal surface black, glossy, with small spots of white pubescence.

Head quadrangular, transverse, flattened, glossy, narrower than pronotum, dorsal surface with with very fine reticulate microsculpture. Eyes not extended, bilobate. Middle porrtion of head between eyes with short, rudimental, but somewhat elongate, narrow line, and postocular portions with wide pand of white pubescence, which not continuing on pronotum. Cheeks narrow, not extended, covered with dense white tomentum. Clypeus yellow, narrow, convex, shiny. Labrum bicolorous: basal part dark brown, covered with dark pubescence, and apical part yellow, with yellow pubescence. Dorsal surface of labrum dark, with transverse row of long setae in median portion. Mandibles massive, shiny, acute apically, each laterobasal parts with pale tomentum and several dark setae. Maxillary and labial palpomeres dark, with yellow-brown apex. Antennae slender, relatively short, with brown, slightly darkened antennomeres, except black antennomeres 1-3. Antennomeres covered with fine and sparse tomentum, except for antennomere 4 with dense, white pubescence.

Pronotum transverse, wider than head and narrower than elytra, with two narrow, transverse, parallel, slightly curved lines in basal and apical portions. Portion between apical and basal lines without coarse punctation. Lateral sides of pronotum rounded, without visible angles. Dorsal portion of pronotum smooth, without sparse punctures, with several fine punctures, shiny. Lateral sides of pronotum with small, longitudinal, sligthly curved band of white pubescence.

Legs short, thick, black, shiny, covered with fine pubescence. Tibia covered with dense grey tomentum, with dark, dense setae on apical portion. Tarsomeres covered with dense, mixed, grey pubescence; apical tarsomere with lateral rows of yellow setae.

Scutellum rounded apically, covered with sparse, white tomentum. Pars stridens not visible under basal margin of pronotum.

Elytra somewhat parallel-sided, with slightly curved lateral sides, black, shiny, covered with sparse, fine pubescence. Shoulders distinct. Each elytron with distinct humps behind shoulders. Latero-apical portions of each elytron with large spot of white pubescence, and with several small white spots behind it; apical portions of each ellytron with transverse band of white pubes-

cence. Elytral suture dark brown in about middle. Apex of elytra widely rounded.

Upper side of body mostly covered with white pubescence. Prosternum and mesosternum with dense white pubescence. Abdominal ventricles with dense grey pubescence.

Differential diagnosis. The new species is similar to the nominative susbspecies P. weigeli weigeli Vives, 1938 , but differs by different shapes of bands on the elytra: white drawing on the latero-apical portions of the elytra of a new subspecies without transverse band, only with rounded white spot, but in apical portion with transverse interrupted band of white pubescence, while latero-apical portions of the elyta of P weigeli weigeli with white band behind shoulders and preapical transverse band absent.

Etymology. Patronymic, the species is named to honour my colleague Vadim Voitsekhovski ( Indonesia), the collector of the type specimen.
