<paragraph pageId="0" pageNumber="135">Males (Figs 5, 6, 15). Body length 9.8-10.3 mm; greatest width 6.0-6.4 mm. Form ovate, sides subparallel. Body overall black with dorsum shiny. Antennal clubs yellowish brown to black. Head: Labrum with anterior margin shallowly concave centrally, sides notched, surface coarsely, transversely rugose. Labrum and mandibles visible beyond clypeus when viewed dorsally. Clypeus subtrapezoidal, anterior margin beaded with or without a small convexity at middle, protrusion at basal angle moderately to weakly developed, surface coarsely, transversely rugose. Clypeofrontal suture vaguely indicated. Frons with a small conical convexity at center, tip rounded or weakly bilobed. Eye small, canthus wide and simple (Fig. 21). Thorax: Anterior side of pronotum behind head sharply declivous with a shallow fossa either side of midline, midline deeply indented on basal half along with coarse punctures. Surface of pronotum with tiny, secondary punctures sparsely distributed evenly, coarse punctures in fossae and both sides of pronotum, sides of basal half of midline and base of pronotum almost impunctate. Fovea vestigial. Scutellum with scattered secondary punctures, slightly longer than wide medially. Elytron: With 7 punctate striae between suture and humeral umbone, punctures coarse, stria 2 interrupted by stria 1 not reaching base, stria 5 terminated in length subequal to stria 2; intervals 1, 3 and 4 more convex and wider than others, interval 2 less convex than others. Legs: Protibia with 9 distinct teeth on outer margin, apical 3 teeth protruding, tip of apical tooth sharp and curved outwardly. Male genitalia: Parameres one-third as long as basal piece, swollen when viewed laterally, strongly sclerotized at base (Figs 27, 28, 34); surface sparsely to moderately punctate with a tuft of long setae located at dorsal base of each paramere. Median lobe bilobate with dorsal sclerite largely reduced within temones; lateral sclerites elongate with apex fimbriate-like; supporting sclerites absent. Internal sac absent. Temones long, strongly sclerotized. Basal piece with apical portion asymmetrical, dorsal base with a few setiferous punctures.</paragraph>

sp. n. has its distribution over the neighboring small islands (Map 1) of Luzon and probably also occurs throughout the main island. A noticeable female was collected from Dinagat Island (Map 1), approximately 700 km SE of the nearest known locality of species in Luzon. Further investigation of the species distribution is needed.
