EL: 2.2 mm, EW: 1.7 mm, PL: 0.7 mm, PW: 1.5 mm. Colour: Dorsal and ventral sides black; lateral margin of the pronotum brown; tibia light brown, tarsal claws light brown; 2nd to 9th AS light brown, 1st and 10th AS dark brown.

Body ( Fig. 1 ). Head coarsely punctate with long light brown setation. Palpi entirely yellowish-brown; setation on mentum denser. Eye very large, with brown microsetae. Ocellus on front present ( Fig. 4 ). Antennae with mixture of white and black setae, with ten antennomeres and 11th AS missing, quadrilateral with apical abdomen; 4 ‒ head frontal; 5 ‒ left antennae; 6 ‒ genitalia ventral.

end longest, width increased from 1st to 6th AS and decreases towards the apical end ( Fig. 5 ). Antennal fossa circular. Pronotum slightly more sparsely punctate compared to head, relatively consistent density of punctures, with relatively long yellowish-brown setation, and slightly shorter black station, most of the setae in the middle of pronotum may be eroded. Scutellum triangular, anterior end convex,

without setation. Elytra coarsely punctate; surface reddish brown to black with three white bands of setation with black covering the rest of the surface, most of the setae in the middle of pronotum may be eroded ( Fig. 1 ).

apical end slightly rounded. Phallobase: nearly symmetrical, oval.
