( Fig. 3 )

Type material. HOLOTYPE, male ( Fig. 3 ): PHILIPPINES — Mindanao / Agusan del Sur / Borbon / IX.2018 / local collector ( DUBC), printed on red card.

Description. Measurements: LB: 13.0 mm. WH: 3.0 mm. LG: 2.0 mm. LL: 0.8 mm. WL: 0.7 mm. LP: 3.0 mm. WP: 3.0 mm. LE: 8.0 mm. WEH: 5.0 mm.

Adult male. Teguments matte black, tomentose, densely covered with minute recumbent black pubescence interrupted with bands of yellowish pubescence on head, pronotum and elytra.

Head matte black, with two parallel yellowish recumbent pubescence from the base towards frons; labrum glabrous, dark brown; mandibles and genae covered with yellowish recumbent pubescence; eyes matte black, rectangular, back of the eyes reaching margin of the head covered with black pubescence.

Antennae matte black covered with erect black setae; setae longer or prominent from scape reaching antennomere 5, the rest narrower; scape with apical cicatrix; antennomere 3 longer than scape; antennomere 4 as long as scape; antennomeres 3–5 with scant yellowish recumbent pubescence near the base.

Pronotum as long as wide, parallel, unarmed, slightly convex on the disc, covered with yellowish recumbent pubescence interrupted with a V-shaped black pattern near the apical margin and few erect black scattered setae near the basal margin. Scutellum rounded, black, covered with black pubescence along the middle ( Fig. 3 ).

Elytra 1.6x longer than wide, matte black, with three white recumbent bands of pubescence: one broad before the middle, extending from margin to the elytral suture, and two narrow bands, one in the apical third, the other from apical declivity towards the apex interrupted with small band of black recumbent pubescence. Elytral margin lined with few erect black setae from the apical third towards apex.

Coxae matte black; trochanters dark brown; femora and tibia densely covered with recumbent white pubescence with few erect white setae; tarsi dorsally covered with dense black recumbent pubescence; ventrally dark brown; claws dark brown, sparsely covered with black setae, appendiculate.

Ventral side towards the abdomen covered with whitish gray pubescence; prosternum, mesosternum, metasternum and abdominal sternites densely covered with white recumbent pubescence at the lateral sides, whitish on the middle; pygidium widely ovate at apex, densely covered with yellowish and black erect setae.

Paramere broad tapering towards the base; apex with dense erect setae. Aedeagus lanceolate, tapering towards the apex, slightly recurved. Endophallus as long as aedeagus, with two thin rows of spines, broader group of spines towards apical end; a separate group of spines forming a circular pattern near the apex.

Adult Female. Unknown.

Differential diagnosis. Cacia (Ipocregyes) manobo sp. nov. belongs to the subgenus Ipocregyes especially by antennomere III without apical spine, tuft of hairs, and not inflated at the inner side. Cacia hieroglyphyca differs from it by the pronotum fully covered with whitish recumbent pubescence and one third of the elytra with narrow whitish recumbent pubescence near the apex. Cacia ulula and C. vermiculata having only one band of white recumbent pubescence on the elytra ( C.vermiculata ) instead of three bands ( Cacia manobo sp. nov.) and a thin highly undulate band of white recumbent pubescence ( C. ulula ) instead of a broad lateral band of yellowish recumbent pubescence ( Cacia manobo sp. nov.).

Etymology. Cacia (Ipocregyes) manobo is dedicated to the Manobo, a tribe habiting the island of Mindanao, Philippines. The name is a substantive in apposition.

Distribution. Philippines: Mindanao (Agusan del Sur).
