( Fig. 2 )

Type material. HOLOTYPUS, male: Philippines: Leyte isl., / St. Bernard, / 04.2017. loc. coll. [handwritten]; // HOLOTYPUS: / Pseudocomeron / vitalii sp. nov. / A.Barševskis det. 2021 [red label, handwritten] ( DUBC).

General distribution: Philippines: Leyte island.

Description. Body length: 9.9 mm, body width: 4.3 mm. Dorsal surface dark-brown, with grey, yellow-brown and white pubescence. Each elytron with postbasal discal gibbosity.

Head quadrangular, flattened, with fine dorsal punctation, microsculpture, and white and yellow pubescence, forming symmetric broad and pale spot resembling a butterfly with open wings. Eyes relatively small, slightly extended, bilobate. Cheeks narrow, not extended, with pale tomentum. Clypeus narrow, transverse, shiny, brown. Labrum dark, covered with yellowish pubescence and long setae. Mandibles with acute apices, relatively narrow, laterobasal parts with yellow pubescence. Antennae relatively short and thin, with dark-brown antennomeres; antennomere 2 with coarse punctures and dark tomentum; inner side of all antennomeres with row of setae.

Pronotum narrower than elytra, with transverse basal impression, dorsally covered with yellow and laterally with yellowish-white pubescence and numerous sparse and coarse dark punctures. Basal angles of pronotum rounded, not visible.

Legs dark-brown, covered with grey and yellowish fine pubescence. Tarsomeres dark-brown, with very fine and sparse tomentum dorsally.

Scutellum subpentagonal, with slightly pointed apex, covered with dense, yellowish pubescence. Pars stridens not visible under basal margin of pronotum.

Elytra uneven. Each elytron with distinctly elevated postbasal discal protuberances, covered with yellow-brown pubescence; lateral part behind middle of each elytron with transverse and oblique spot of white pubescence, behind the pubescence is slightly scrubbed Elytra covered with sparse, coarse setiferous punctures, coarser in basal portion around discal protuberances.

Ventral side of body covered with dense yellow-brown pubescence, and sparse and coarse punctation.

Female unknown.

Differential diagnosis. The new species is similar to P. luzonicum from Luzon, but differs from it by different coloration of elytra. Elytra of a new species with transverse, oblique spot of white pubescence, lateral sides of pronotum and head with pale yellowish pubescence, while elytra, pronotum and head of P. luzonicum covered with unicolor brown pubescence, without transverse spot of white pubescence.

Etymology. Patronymic. This species is named after my colleague, cerambycidologist Francesco Vitali ( Luxembourg) in appreciation of cooperation, and in gratitude for his great contributions

Barševskis A.

to the knowledge of Cerambycidae of the world fauna.
