Tuber oculorum conspicuously large, wider than long, medially grooved, with lateral denticles, about one-quarter to half its length from front margin of cephalothorax. Pedipalp robust and powerful; femur, tibia and tarsus with long spines (fewer on tibia and tarsus); patella and tibia each with conspicuous medio-distal apophysis, form of patellar apophysis usually varying between sexes. Truncus penis extremely long and narrow, with nearly parallel margins, basally slightly enlarged, either dorsally or ventrally flat, otherwise convex; muscles in basal third to basal half. Glans elongate spindle-shaped; sense bristles large, in bright socket, near base of glans. Receptaculum seminis mostly thick-walled.
