Redescription.— Body elongate, dorsal surface pruinose ( Fig. 1 ). Antenniferous tubercles subparallel. Head broad. Antenna long, slender, segment IV fusiform and slightly broader; light brown to brown; with short decumbent setae more abundant at apex; first segment shorter than half interocular width.

Scale­like setae posteriorly on anterior pronotal lobe, transverse sulci, and anterior half of posterior pronotal lobe. Scutellum dark brown, with scale­like setae, punctuate. Hemelytra coloration pattern as in fig. 1. Hemelytra almost reaching abdominal apex. Pleura dark brown except proepimeron brown to light brown and metaepimeron contrastingly light brown; acetabular areas brown to light brown; punctuate; with short, decumbent setae. Coxa, trochanter, femur, meso­ and metatibia basally, and pretarsi dark brown; tibia and tarsi light brown. Abdomen brown, with short abundant decumbent setae.
