Description

Male

Crawley (1925) - Length 5.5 mm.

Smaller and slenderer than the type. Entirely black except for the ferruginous tarsi and apical segments of gaster. Scape somewhat thicker. Sculpture of postpetiole and first segment of gaster much coarser, consisting of irregular striae encircling the base of the postpetiole, together with a few elongate punctures. The following segment is longitudinally reticulate-punctate with small isolated punctures here and there. Both segments shining. Otherwise like the male of metallica.
