one and one-half diameters apart, almost two from laterals. Posterior 
median eyes one diameter apart, one and one-half from laterals. Cheli-

It is uncertain if females have been correctly separated from C. 
ecuadorensis. Females of C. vittatula have a dark spot posterior in the 
light area of the epigynum (Fig. 40). No other differences were 
noted. The male palpi, however, are very distinct (Figs. 41, 42). 
Only the availability of larger collections will permit finding charac- 
ters separating the females. Illustrations were made from the syntypes. 
Distribution. Colombia to Bolivia.
