Pronotum transverse, finely alutaceous
, moderately convex, laterally feebly explanate, distinctly and irregularly punctured; punctation somewhat coarser and denser on sides; latter subparallel, distinctly bordered, edge almost thin, rather elongately and sparsely ciliate; hind angles obliquely truncate; base bisinuate, not bordered.

7): The adult was described in detail by Froeschner (1960), and within the genus, this species can be recognized by the large terminal lobe on the peritreme and by the distinctly alutaceous
Frons very delicately coriaceous to alutaceous
, with very few short white setae, in some specimens darker than the rest of head, especially towards the frontal ocellus; central area slightly impressed right before the frontal ocellus.
