Figure 1. Chelifer fuscipes Banks. From below and above. ×25.
Figure 2. Chelifer fuscipes, third leg and mandible much enlarged.
Cephalothorax: As long as it is broad. Upper edge almost truncate, yet rounded; sides evenly convex, lower edge almost straight. Cephalothorax finely granulate and heavy, simple spine-like hairs placed in a definite order. One distinct median suture. Two eye spots.
Abdomen: Half as broad as it is long and divided into twelve scuta. The outer edges of each scutum are prolonged into curved hooked spines. The first scutum is the shortest and broadest, and has the heavier spine or hook, while the last two segments often lack the hook. The abdomen is finely granulate and at the lower edge of each scutum there are eight heavy, short, simple hairs.
Pedipalps: Longer than body, coxa smooth, trochanter with large protuberance ending in a strong spine on outer side; femur longer than cephalothorax, slightly concave on inner edge, convex on outer edge. Tibia pedicellate, shorter than femur. The trochanter, femur and tibia are all granulate and sparsely covered with short, simple hairs. Claw large, hand broad, smoothly convex on both sides; finger as long as the hand and slightly curved. It is also provided with long, tactile hairs.
