Description
Nops ursumus Chickering, 1967
Figures 42A‒F; 43A‒L
Nops maculata: Banks, 1929: 55 (not Nops maculata Simon).
Nops ursumus Chickering, 1967: 16, figs 20–21. Male holotype from Barro Colorado Island (9°9′19″N, 79°50′54″W), Canal Zone, Panama, berlese funnel, iv–vi 1950, J. Zetek (MCZ 23413); female paratype, same data as holotype, 15.i.1958, A. M. Chickering (MCZ 128576); male paratype, same data as holotype (MCZ); all types examined.
Remarks. The specimen recorded from Panama as Nops maculata by Banks (1929) was transferred to Nops ursumus by Chickering (1967). This specimen is an immature female but has the diagnostic abdominal dorsal pattern of Nops ursumus.

Diagnosis. Both sexes can easily be separated from members of all the other Central American congeners by having five, dark gray, irregular, transversal chevron stripes extending dosolaterally on the abdomen (Fig. 42A, D).
Description. Male (holotype): Carapace dark orange (Fig. 42A). Chelicerae, labium, endites, legs and coxae orange. Sternum orange, ligther than carapace. Abdomen light pale gray, with five, dark gray, irregular, transversal chevron stripes extending dosolaterally in the abdomen (Fig. 42A); ventrally with two irregular grayish spots close to spinnerets. Total length 9.8. Carapace 5.9 long, 3.5 wide. Sternum 4.5 long, 3.5 wide. Leg measurements: I: 4.4; II: 4.3; III: 3.8; IV: 4.6. Posterior unpaired claws elongated and dorsally reflexed (Fig. 43I). PLS same size as PMS. Palp with embolus distinctly shorter than tibia, thick and strongly curved; tip with two ventral short extensions (Fig. 43C‒D).
Female (MCZ 128576): Carapace, chelicerae, labium, legs, coxae, endites and sternum as in male, but a little darker (Fig. 42D). Abdomen as in male. Total length 10.2. Carapace 6.15 long, 3.9 wide. Sternum 4.75 long, 3.9 wide. Leg measurements: I: 4.55; II: 4.4; III: 3.95; IV: 4.75. Posterior unpaired claws and PLS as in male.

Internal genitalia with receptaculum without invagination and uterus externus with narrow base (Figs 42F; 43G‒I).

Distribution. Known only from Panama (Fig. 42G).
