Eleuterio Jr. C. Avergonzado, Milton Norman D. Medina recurved, lanceolate, and highly cuspidate apex, tegmen long, paramere longer than wide, closed, apex lined with long, soft, and erect yellowish setae ( Fig. 2 View Figure 2 ).

Adult female. There is no sexual dimorphism between males and females except that the antennae of females are shorter than males. The body of females is more robust than males.

Differential diagnosis. The new species closely resemble P. diverseguttata albopunctata ( Breuning, 1982) but differs in the following characteristics: Plocia barsevskisi Medina & Avergonzado sp. nov. have a pronotum covered with very shallow punctures (vs. deep punctures in P. diverseguttata albopunctata ), elytra are translucent with visible reticulations (vs. absent in P. diverseguttata albopunctata ), differ- ences in elytral maculations ( Fig. 1 View Figure 1 A-B), deep uniformly arranged puncturations at frons (vs. scattered shallow punctures in P.diverseguttata albopunctata ). Lateral margin lined with thin yellowish recumbent pubescence (vs. thick band in P. diverseguttata albopunctata ). Parameres closed (vs. parameres open in P.diverseguttata albopunctata ); apex of aedeagus cuspidate (vs. acute in P. diverseguttata albopunctata ) ( Fig. 2 View Figure 2 ). The new species also differs from other P. diverseguttata species group based on the arrangement of bands of whitish pubescence at elytra.

Etymology. The new species is named after Dr. Arvids Barsevskis of Daugavpils University, Latvia, a good friend and colleague working on the taxonomy of Philippine Cerambycidae .

Distribution. Philippines: Mindanao (Mt. Candalaga, Maragusan, Davao de Oro).
