One specimen had light bands around the dorsal sclerotized patches. The illustrations were made from specimens from Escazu, Costa Rica. Diagnosis. This species is distinguished from C. ojeda and C. tamanaco by the oval to circular markings of the abdomen (Figs. 427-429). It differs from C. alayoni by having the median plate of the epigynum narrower (Figs. 425, 426). Distribution. Guatemala to Costa Rica (Map 6F). Specimens Examined.
