ETYMOLOGY: The specific name, an adjective, is derived from the name of the

paratype
. Total length 1.58. Carapace modified as shown in Figs 125 & 126, 0.75 long, 0.53 wide, pale brown with indistinct radial bands. Chelicerae 0.20 long, unmodified. Both

have white, almost transparent (probably bleach) legs. Leg I 2.10 long (0.60+0.15+0.60+0.45+0.30), IV 2.18 long (0.60+0.18+0.60+0.50+0.30). Chaetotaxy unclear because spines lost. Trichobothria on legs not found. Palp (Figs 127-129): Distal part of palpal tibia elongated and claw-shaped. Protegulum conical, membraneous. Radix without anterior radical process. Embolus with a wide membraneous edge, coiled. Abdomen 0.83 long, 0.55 wide, grey.
