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 View Figure ).

Description. Male (holotype): Carapace dark orange ( Fig. 42A View Figure ). 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 View Figure ); 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 View Figure ). PLS same size as PMSAbout PMS. Palp with embolus distinctly shorter than tibia, thick and strongly curved; tip with two ventral short extensions ( Fig. 43C‒D View Figure ).

Female ( MCZAbout MCZ 128576): Carapace, chelicerae, labium, legs, coxae, endites and sternum as in male, but a little darker ( Fig. 42D View Figure ). 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. External genital area with strongly sclerotized anterior plate, strongly sclerotized lep and remarkable ess ( Fig. 42E View Figure ). Internal genitalia with receptaculum without invagination and uterus externus with narrow base ( Figs 42F View Figure ; 43G‒I).

Natural history. Several specimens were captured with berlese in leaf litter. Apparently abundant in Barro Colorado Island.

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