Construction of the Imago
The abdomen ( abdominal ) attaches Oligoclada pachystigma -Männchen 14.3 to 17.5 millimeters. In females, the length fluctuates a little less with 15 to 16.1 millimeters. The female abdomen is yellowish brown and darkens towards the back. The underside is just as dark to black. The female thorax is also brown and has yellow markings. The hind wings measure between 17.4 and 21.0 millimeters in the males. Those of the females are slightly larger at 20.3 to 22.0 millimeters. The wing mark ( pterostigma ) reaches 1.5 to 2.3 millimeters in the males and 1.8 to 1.1 millimeters in the females. The number of anterodal veins is eight to ten and a half in the fore wing and five to seven in the hind wing.
