Diagnosis

This species is generally lighter than H. coriaceus . The male is easily recognized by the structure of the chelicerae that have long processes on the inner edges of the dorsal surface ( Figs 28B View Fig , 29B View Fig ), and lacks a dichotomous retromarginal tooth which is present in the other species. The embolus is clearly shorter and wider than in H. coriaceus (cf. Fig. 28D View Fig with Fig. 26D View Fig ). The female differs from that of H. coriaceus by the lack of epigynal pockets.

Etymology

The specific epithet is Latin, meaning ‘horned’ and refers to the chelicera form.
