Description. Dimensions of holotype: LB: 11.5 mm. WH: 1.5 mm. LL: 0.8 mm. WL: 1.0 mm. LP: 2-.0 mm. WP: 2.5 mm. LE: 8.5 mm. WEH: 4.0 mm.

Adult female. Teguments in the Head, pronotum, elytra, and legs are matte black; antennae and underside of head are dark brown. Head dorsally wider than long; frons, vertex, genae with puncturations and lateral sides covered with recumbent yellowish pubescence; deeper puncturations at frons arranged in random; dorsal median side of vertex free of yellowish recumbent pubescence; one black erect orbital setae; base of frons lined with 3-4 semi-erect black setae; genae lustrous, wider than long; clypleus lustrous, glabrous, rectangular; mandible short robust at base, covered with few long yellowish erect setae. Antennae short, reaching until apical third of elytra, densely covered with semi-erect short yellowish setae from scape to antennomere XI; scape robust, normal without apical cicatrix, apex rounded, a little longer than head; pedicle slightly elongated; antennomere III as long as antennomere IV; basal half of antennomere III and IV covered with whitish pubescence; antennomere VII fully covered with whitish pubescence.

Prothorax. Pronotum and Propleuron covered with deep puncturations; pronotum wider than long, median line of pronotum free of yellowish pubescence, lateral sides

80 of pronotum to pleuron covered with yellowish pubescence in line with the yellowish pubescence of the head, with few erect black setae at propleuron. Prosternum covered with fine yellowish recumbent pubescence, bottle-shaped in the middle.

Elytra twice wider than long, covered with fine semi-erect and recumbent yellowish and whitish pubescence with pronounced yellowish recumbent pubescence at basal third. Elytra densely covered with puncturations at the basal half, apical half is devoid of puncturations. At least 4-5 visible striae from elytral suture, gradually diminishing from the apical half towards apex. With a distinct lateral band of whitish pubescence at the middle in line with antennomere VII (fully covered with whitish pubescence). At least five longitudinal bands of whitish pubescence scattered at the apical third and elytral apex. Elytral apex caudate with a pointed sutural spine covered with semi-erect whitish and yellowish pubescence.

Legs. Coxa, underside of tibia, profemora, and mesofemora are covered with fine yellowish recumbent pubescence; dorsal side of tibia and tarsi with semi-erect whitish and yellowish pubescence; basal half of metafemora with whitish recumbent pubescence, apical half with yellowish pubescence. Claws simple, light brown, glabrous.

Mesepimeron, metepisternum, and lateral sides of metasternum with deep puncturations arranged in random, covered with yellowish recumbent pubescence, more pronounced at the lateral sides of metasternum. Mesepisternum devoid of puncturations, densely covered with fine black and yellowish pubescence. Mesosternum quadrangular, almost cube-liked, with fine yellowish pubescence. Metasternum wider than long, median line devoid of puncturations and yellowish pubescence with prominent medial concavity. Abdominal ventrite I as long as wide as metasternum; lateral sides of ventrites I to V densely covered with yellowish and bluish recumbent pubescence; median plane of ventrites I and II with very fine yellowish pubescence; ventrites III and IV devoid of pubescence; ventrite V with brownish setae with semi-erect whitish setae at lateral side near the apex.

Adult male. Unknown.

Differential diagnosis. The new species is unique amongst the congeners of Plocia spp. in the Philippines. It is distinct for having no whitish or yellowish macules in the elytra but having a transverse band of whitish pubescence in the middle, and a head including frons highly punctate. It is somewhat close to P. notata ( Newman, 1842) for having a whitish pubescence at antennomeres IV, but distinct from P. notata for being two-toned tomentose at antennomere III.

Etymology. Plocia maglanai sp. nov. is named after Dr. Wenifredo Maglana, a medical doctor and a conservationist who dedicated his life to protecting watersheds and natural reserves in Davao de Oro, Philippines.

Distribution. Philippines: Mindanao (Davao de Oro, Pantukan, Compostela Valley).
