The eyes are close together and more or less equally spaced. The grooves in which the fangs of the chelicerae rest have two teeth on the outer margin and one on the inner margin. The male's maxillae each have an outgrowth (apophysis) that is absent in females.
Both sexes are generally dark brown in colour, with some paler and whitish hairs, and a metallic sheen on the head. Males tend to be darker, the abdomen being described as black rather than brownish-black. The anterior eyes have a fringe of pale and long brown hairs, particularly behind the eyes in females.
