Abstract

Data on the visual behaviour of Hendea myersi cavernicola (Forster) are provided which demonstrate that this harvestman can see. Since no specimens could be trapped outside the cave and the integument of this species displays a reduction in pigmentation, we have to conclude that we are dealing with a troglobite which not only possesses eyes, but actually uses them.
