Head wider than long, highly punctate randomly arranged. Frons densely covered with very fine yellowish recumbent setae, densely covered with relatively deep punctures arranged randomly apical side with 2-4 elongated black erect setae ( Fig. 3C View Figure 3 ). Genae longer than wide, lustrous, sparsely covered with recumbent yellowish pubescence, with few deep punctures. Eyes wider than long, matte dark brown, margin with slight traces of deep punctures; upper eye lobe with two black erect supra orbital setae. Clypeus elongated rectangular, lustrous golden yellow, glabrous. Labrum wider than long, highly punctate, black, densely covered with short yellowish semi-recumbent pubescence with few erect hairs. Mandible lustrous, robust at the base, with yellowish pubescence at each side. Antennae long, reaching apex of elytra, underside of antennae lined with semi-erect setae, dorsal side sparsely covered with semi-erect short setae; scape robust and normal, densely covered with very fine setae, longer than the head reaching basal quarter of pronotum; pedicel short about 0.5 mm, longer than wide, semi-clubbed shape most in lateral view, apex of pedicel truncated; antennomere III slightly longer than IV; antennomere IV slightly curved, twice longer than antennomere V and VI; antennomere VII fully covered with whitish recumbent pubescence; antennomere VIII-XI almost the same length.

Prothorax. Pronotum slightly elongated, bellshaped dorsally, dorsal to lateral sides of disc densely covered with random deep punctures, base at lateral side with very slight traces of very fine recumbent setae, apical half to apex covered with yellowish recumbent setae, each lateral margin and propleuron lined with thin yellowish recumbent pubescence.

Elytra twice longer than wide, basal half-covered with deep puncturations arranged in rows, apical half devoid of puncturations; margins slightly raise, with highly pointed apical suture. Elytral band of whitish pubescence arranged as follows: one horizontal band near margin lining the apical half towards apex, transverse semi

270 acute band at the middle, relatively thick band of soft whitish setae at apex ( Fig. 3A View Figure 3 ).

Legs. Procoxae raised, mesocoxae slightly raised, metacoxae not raised. Femora robust in apical half, with small white very fine yellowish recumbent setae; tibiae with very fine recumbent pubescence at base, semi-erected yellowish setae at apex. Tarsi dorsal aspect with long black semi-erect setae and recumbent yellowish-whitish pubescence, underside was covered with whitish pubescence. Claws simple, brown, glabrous.

Mesepimeron, metepisternum with deep punctures arranged sparsely and yellowish recumbent setae; metasternum with deep punctures at each side, devoid of punctures at the middle, middle with very fine recumbent setae. Ventrites lustrous black, covered with very short pubescence, lateral side with small lump of whitish recumbent setae, ventrite I longer than ventrite II-V, II of the same length of ventrite III and IV, ventrite V longer than ventrite IV, III and II ( Fig. 3B View Figure 3 ). Aedeagus longer than endophallus, recurved, lanceolate, and rounded at apex; tegmen as long as aedeagus; paramere wider than long, closed, covered with erect long soft yellowish setae; endophallus longer than tegmen ( Fig. 4 View Figure 4 ).

Adult female. Unknown.

Differential diagnosis. The new species closely resembles P. splendens Hüdepohl, 1995 but differs in many ways: P. vivesi Medina & Avergonzado sp. nov. dorsally, have deep punctures arranged randomly, particularly in the head, pronotum, and basal half of elytra (vs. fine and relatively shallow punctures in P. splendens ); both species differ in elytral band of whitish pubescence. This species also resembles P. maglanai Medina, 2023 but has no transverse bands of yellowish pubescence at elytra.

Etymology. This new species is named after Dr. Eduard Vives, a good friend and colleague working on the taxonomy of Philippine Cerambycidae .

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

Two new species of the genus Plocia Newman, 1842 ( Cerambycidae : Lamiinae : Apomecynini ) from Davao de Oro, Mindanao Island Philippines
