Remarks . Female holotype of Nops maculatus from Caracas, Venezuela is in bad condition of preservation. However, the abdominal pattern is intact, which matches with the abdominal pattern of other specimens examined from Venezuela , including males. All these Venezuelan specimens are conspecific with the types and other material examined of Nops craneae Chickering from Trinidad and Tobago . Therefore, both species are synonymized herein.

Both sexes resemble the similar congener N. amazonas n. sp. by having similar abdominal pattern as in figure 6J, and PLS two times longer than PMS; but can be distinguished by having the embolus curved to the prolateral side in males ( Fig. 56B‒D ) and females with narrow invagination on receptaculum ( Figs 56G ; 57F). Description . Male (MCZ 20920): Carapace dark reddish orange ( Figs. 56A ). Chelicerae, labium, endites, legs and coxae reddish orange, metarsi and tarsi lighter. Sternum reddish orange. Abdomen light pale gray, with an irregular, median, dark gray, stripe extends throughout the dorsum; on each dorsolateral sides there is a series of four irregular, elongated dark gray spot the last of which spreads and unite with the median stripe distally, and ventrally with a pair of larger gray spot in a ventrolateral position and two small, irregular and dark gray spot distally close to spinnerets ( Figs. 56A ). Anal tubercle and spinnerets whitish gray. Total length 9.5. Carapace 5.5 long, 4.7 wide. Sternum 4.5 long, 4.0 wide. Leg measurements: I: 4.1; II: 4.0; III: 3.7; IV: 4.25. Posterior unpaired claws small, as in other three‒clawed spiders. PLS longer than PMS. Palp with embolus distinctly longer than tibia, thin and curved to the prolateral side ( Fig. 56B‒D ); beveled embolar tip, with one ventral short extension ( Fig. 57D‒E ). Female (MCZ 128294): Carapace, chelicerae, labium, legs, coxae, endites and sternum as in male, but a little darker. Abdomen as in male ( Fig. 56E ). Total length 10.1. Carapace 5.9 long, 5.0 wide. Sternum 4.95 long, 4.4 wide. Leg measurements: I: 4.3; II: 4.2; III: 3.8; IV: 4.4. Posterior unpaired claws and PLS as in male. External genital area with weakly sclerotized anterior plate, strongly sclerotized lep and remarkable ess ( Fig. 56F ). Internal genitalia with narrow invagination on receptaculum and uterus externus with narrow base ( Figs 56G ; 57F). Distribution . Known from Venezuela , Guyana and Trinidad Island ( Fig. 57G ).
