Materials examined: Paratype male, PHILIPPINES –Panay Island, Antique Province, Culasi, v.2018, loc. coll. DUBC . Paratype female, PHILIPPINES –the same label as male .

Measurements of the various body parts are as follows: Males (n=1): LB ( LH +LP+ LE) = 12.5 mm; LH = 1.5 mm; WH = 2.5 mm; LP = 2.5 mm; WP = 3.5 mm; LE = 8.5 mm; WEH = 4.0 mm. Females (n=1): LB ( LH +LP+ LE) = 14.0 mm; LH = 1.5 mm; WH = 2.5 mm; LP = 2.5 mm; WP = 4.5 mm; LE = 10.0 mm; WEH = 5.5 mm.

Redescription. Adult male. Tegument. Head, prothorax, abdomen, and legs dark brown to matte black.

Head. Frons densely covered with whitish and yellowish recumbent pubescence, with few long semi-erect black setae lining at apex of the head, and anterior sides of both eyes and genae. Lower eye lobe dark brown, as long as wide. Vertex steep, antennal support raised.

Antennae more than twice longer than the body, antennomeres III to V of the same lengths, antennomeres covered with very fine whitish or black recumbent pubescence.

Prothorax. Pronotum almost twice wider than long, armed at both sides covered with a thick band of whitish recumbent pubescence. Prosternum and Propleuron covered with whitish or yellowish recumbent pubescence. Elytra with deep punctures randomly distributed from base to apical third, finer towards apex; with three bands of whitish recumbent pubescence arranged as follows: one at pre-median near apical third a thick zigzag band of whitish recumbent pubescence from elytral margin up to near suture; second at post-median, relatively thick band of whitish pubescence from elytral margin up to near suture; and third, a thick U-shaped band of whitish near elytral apex. Humeri angled, slightly raised. Apex truncated, margin lined with fine semi-erect yellowish pubescence.

Mesosternum angled when viewed laterally; mesepimeron, metepisternum, metasternum and abdominal ventrites densely covered with whitish and black recumbent pubescence; mesepisternum paralleled, lanceolate towards apex, lateral ends moderately depressed.

Legs dark brown to matte black, covered with whitish or yellowish recumbent pubescence; claw dark brown, glabrous.

Genitalia. Endophallus is more than twice as long as the whole system of genitalia; the endophallus is very thin ( Fig. 4C View FIGURE 4 ). Postmedian of the aedeagus towards apex bottle-shaped strongly recurved when viewed ventrally, highly recurved when viewed laterally; apex of aedeagus steeply angled and highly pointed (Fig. E). Tegmen broad yellowish, parameres broad does not meet at the apex; apex of parameres lined with long erect yellowish setae (Fig. K).

Adult female. The female is morphologically similar to males except females are generally larger than males. Antennomeres III to VI in females are two-toned with a small band of whitish pubescence at the basal third or half, the rest is black recumbent pubescence; a very faint band of whitish pubescence at the basal end of antennomere VII. Males do not have two-toned antennomeres, all antennomeres are non-banded.

Distribution: Philippines (Visayas: Panay Province, Antique, Culasi).
