of . The head capsule shows a clypeus which is smooth and shiny, a feature seen in the living pilosum group of Apterostigma species. The occiput, rear area of the head capsule, is elongated to a slight neck with a smooth integument surface. The antennae are composed of eleven segments, in which the tip segment is 2.5 times the length of the next segment. The eyes are rounded and bulbous in structure with a circumference of ten ommatidia. While the clypeus structure places A. electropilosum in the pilosum group, the combination of rounded frontal head capsule lobes, mandibles with eleven teeth, and the angle of clypeus border is not seen in any extant species.
