HOLOTYPE male: PHILIPPINES – Southern Luzon, Oriental Mindoro / Puerto Gallera / vi.2017, loc. collector leg. / MMCP, printed on red card. Type specimen will be deposited at the Philippine National Museum ( PNM).

Description. Measurements: Holotype male: LB (LH+LP+LE): mm. LH: 1.5 mm. WH: 2.5 mm. LG: 1.0 mm. LL: 0.5 mm. WL: 0.5 mm. LP: 2.0 mm. WP: 3.0 mm. LE: 8.0 mm. WEH: 4.0 mm.

Teguments head, prothorax, and elytradark brownish; underside of the body, antennae, and legs are light brownish.

Head broader than long; vertex, frons, and genae densely covered with yellowish recumbent pubescence; frons with deep puncturations arranged in random; longitudinal line visible from base to apex; vertex with thick band of yellowish pubescence from base up to margin between frons; genae wider than long; eyes dark brown as long as wide; apical margin of head slightly concave, lined with long erect yellowish setae; clypeus light brownish, lustrous, glabrous; labrum broader than long, densely covered with semi-erect yellowish setae; mandibles lustrous, dark brownish, basal half with puncturations, with lateral depression, and covered with semi-erect yellowish setae. Scape slightly robust towards apex with cicatrix, covered with fined recumbent yellowish pubescence with moderate erect long yellowish setae. Antennomeres III to XI cylindrical, covered with fine recumbent yellowish pubescence, underside with numerous long erect yellowish setae; Antennomere III longer than IV and V combined; antennomeres VI to XI of the same length.

245 Femora robust; femora, tibia, and tarsi covered with fine recumbent yellowish pubescence with few short erect yellowish setae. Claws simple.

Mesosternum quadrangular, with fine recumbent setae; mesepimeron, mesepisternum, metepisternum, metasternum, and abdominal ventrites densely covered with recumbent yellowish pubescence; mesepimeron slightly wider than long; metepisternum rectangular; ventrite I as broad as ventrite V; ventrite I broader than ventrites II, III, and IV individually.

Pronotum and Propleuron with deep puncturations; pronotal disc slightly raised, broadest at the middle; prothorax densely covered with recumbent yellowish pubescence with few erect yellowish setae arranged in random. Elytra twice longer than wide, with dense puncturations from base towards post-median, finer towards apex. Humeri angled and slightly raised. Elytra broadest at humeri tapering towards apex, with three transverse bands of recumbent yellowish pubescence: a transverse band at the base and humeri, a pre-median band from margin to suture, and thick postmedi- an band towards apex. Elytral margin lined with long erect yellowish setae from the lateral side of humeri to apex. Scutellum triangular covered with recumbent yellowish setae.

Procoxa and metacoxa are robust, raised, and covered with fine recumbent pubescence with few erect yellowish setae.

246 Genitalia. Aedeagus (3.0 mm) recurved when viewed laterally, broadest at pre-median, tapering towards apex, apex slightly blunt; tegmen (3.5 mm) longer than aedeagus, parameres four times longer than wide (1.0 mm, 0.25 mm), parallel-sided not meeting from base to apex; apex of parameres lined with long soft erect yellowish setae.

Adult female. Unknown.

Differential diagnosis. This new species belongs to Cacia sēnsū strictō for having an apical spine at antennomere III, and no apical spines in IV and VI. This species is close to C. trimaculata Breuning, 1947 for having three bands of whitish pubescence at the elytra but can be easily differentiated based on the pronotal bands ( C. aeschyae sp. nov. fully covered with yellowish pubescence vs. thick median longitudinal band of whitish pubescence in C. trimaculata ). Both species also differ in terms of elytral bands (thinner bands in C. aeschyae sp. nov. vs. thick circular bands in C. triomaculata ). Cacia aeschyae sp. nov. is distinct for having a body tapering towards apex more robust in C. triomaculata . Finally, antennomere VI of C. triomaculata covered with whitish pubescence, absent in C. aeschyae sp. nov. This new species also differs from Cacia estrellae Hüdepohl, 1989 which can be found in the same biogeographic region for having a muchtapered body form and no two-toned femora.
