of eleven segments, in which the tip segment is 2.25 times the length of the next segment. The eyes are rounded and bulbous in structure with a circumference of twelve ommatidia. The bulbous eyes have a half hemisphere structuring with ommatidia on the sides and front, while the rear sides are integument. The head capsule shows a clypeus which is smooth and shiny, a feature seen in the living pilosum group of Apterostigma species. However the front edge of the clypeus is notably reduced, nearing the absent clypeus border that is a character of the "auriculatum" group. The clypeus structure is most similar to an undescribed pilosum group species collected in Costa Rica, while the eye structure is closest to a "auriculatum" group species A. pariense and A. reburrum. Given the ocular structuring, A. eowilsoni is likely to have had excellent stereoscopic vision but poor side vision and been blind in the rear.
