Diagnosis. Males of Zelotibia curvifemur are recognized by the strongly curved femora, but mainly by the large RTA, originating from the proximal base of the tibia, and the broad embolus which is deeply incised at the tip. Females are characterized by the long, broad depression and the course of the entrance ducts.

Etymology. The specific name curvifemur is a noun in apposition referring to the strongly curved femora.

Description. Male holotype ( Fig. 3 ). Total length 7.75, Carapace 2.50 long and 2.10 wide. Carapace dark brown suffused with dark grey along radiating striae. Chelicerae dark brown. Sternum and labium pale brown. Eyes, AME area dark. Both eye rows straight. Posterior eyes oval. AME: 0.07; ALE: 0.10; PME: 0.07; PLE: 0.10; AME-AME: 0.07; AME-ALE: 0.02; PME-PME: 0.05; PME-PLE: 0.02. Chelicerae: both margins with three teeth. Sternum with long, dark bristles along margin. Labium 0.9 times longer than wide. Legs pale brown. Metatarsi III and IV with ventral preening comb at tip. Tarsi cylindric. Abdomen Dorsum dark grey; with four pale points in central, longitudinal row in anterior half; venter pale grey. Spinnerets pale grey. Palp Femora strongly curved ( Fig. 12 ); tibia with long, curved, RTA, originating at proximal base of tibia, with flat ventral side, rounded tip ( Fig. 13 ). Retrolateral margin of cymbium with triangular extension. Embolus large, curved, deeply incised at tip; dorsal prong with hooked tip. DTA elongate, with both anterior and posterior extremities pointed.
