, the prosternum of this species has a punctate medial depression anterad the prosternal process, in this instance lined with 7 punctures. The prosternal anteapical groove is continuous and distinctly punctate laterally, more irregular and smoother ventrally. The eyes are large and moderately convex, and they cover much of the ocular lobe; EyL/OLL = 0.95. The parascutellar striole is composed of 7-8 deep, isolated pits. Standardized body length 4.9 mm. Setal formula ++/+/+2++.
