and disc without strong track of (Olmi) median longitudinal furrow Acknowledgments
Color and texture: Head: Shiny brown, with opposing dark brown spots or maculae on interocular area and frons; base of clypeus darker brown; surface finely alutaceous
, with a few fine brown-stained punctures on frons.
and minutely punctate, about PIS = PD, anterior margin with three sets of three teeth and two short teeth between lateral and median sets; mandible with two short basal teeth on inner margin, and distinctly incised at the base on outer margin.
Scutellum small, elongate, triangular, alutaceous
, clearly depressed.
Pygidium of female usually with a large apical tubercle; median lateral depressions; large rounded alutaceous
speculum, basally emarginate (fig.
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.
