Materials examined: 2 males, PHILIPPINES – Southern Luzon , Mindoro, Baco, i.2019, loc. Coll. DUBC ; 2 females, PHILIPPINES – Southern Luzon , Mindoro, Mt. Halcon, ii.2015, loc. Coll. DUBC .

Measurements of the various body parts (in range) are as follows: Males (n=2): LB ( LH +LP+ LE) = 15.5 mm; LH = 2.0 mm; WH = 3.0– 3.5 mm; LP = 3.0 mm; WP = 4.5–5.0 mm; LE = 10.5 mm; WEH = 5.5 mm. Females (n=2): LB ( LH +LP+ LE) = 15.6–16.0 mm; LH = 2.0 mm; WH = 2.5–3.0 mm; LP = 2.8–3.0 mm; WP = 4.5–5.0 mm; LE = 10.8–11.0 mm; WEH = 5.5 mm.

Redescription. Adult male. Teguments. Head, prothorax, abdomen, and antennae dark brown to matte black, eyes dark brown. Head wider than long; frons and genae covered with fine whitish to yellowish recumbent pubescence; underside glabrous, dark brown. Antennae dark brown to matte black, more than twice longer than body length, antennomere III shorter than antennomeres IV and V (4.5 mm vs 5.5 mm).

Prothorax. Pronotum wider than long, lateral side armed covered with a thick band of whitish to bluish green recumbent pubescence; basal end lined with thin band of whitish pubescence; median line along the base with a small patch of whitish pubescence. Elytra is twice wider than long, with three bands of whitish to bluish-green recumbent pubescence: with deep punctures randomly distributed from base up to apical third, finer towards apex; one band at apical third, a relatively thick C-shaped band from the elytral margin disrupted at the middle (or connected with a very thin line of pubescence, almost unnoticeable) another thick band from the middle towards near suture; second, a thick C-shaped postmedian from the margin not reaching elytral suture; and third, a thick U or V-shaped band near the elytral apex. Apex is slightly truncated with a very small sutural spine. Legs dark brown to matte black. Claws dark brown.

Mesosternum angled when viewed laterally. Mesepimeron, mesepisternum, metasternum, and metepisternum dark brown to matte black, covered with whitish to yellowish recumbent pubescence. Base of metepisternum covered with relatively thick band of whitish pubescence, paralleled, lanceolate towards apex. Ventrite I longer and broader than ventrite II–IV, densely covered with semi-erect whitish and black pubescence. Ventrite V densely covered with whitish recumbent pubescence and apex lined with long erect yellowish setae.

Genitalia. Endophallus approximately twice longer than the whole system of genitalia ( Fig. 4D View FIGURE 4 ). Tegmen broader at sides; apex of parameres lined with long erect yellowish setae. Aedeagus highly recurved, bottle-shaped at apical third, lanceolate towards a pointed apex ( Figure 4B&G View FIGURE 4 ).

Adult female. Male and female species are morphologically similar except with the following characteristics: Antennomeres III to VIII of females are two-toned, with a band of whitish recumbent pubescence either at the basal third or basal half of antennomeres, the rest with black recumbent pubescence. The band of whitish pubescence at the basal end of antennomere VIII is almost unnoticeable.

Distribution. Philippines (Mindoro).
