Colorados, Pichincha, Ecuador, 22 Dec. 1958 (A. M. Nadler), in 
the American Museum of Natural History. The specific name is a 
noun in apposition after the type locality. 
Description. Carapace, sternum, reddish brown. Legs grayish 
brown. Abdomen whitish. Diameter of anterior median eyes less 
than radius of other eyes. Anterior median eyes less than one diameter 
apart, touching laterals. Posterior median eyes their radius apart, 
almost touching laterals. Legs short. A small transverse, sclerotized

Diagnosis. The embolus is on the ectal side of the palpus as in 
other Styposis (Figs. 2, 3), but is easily visible, and the species is 
thereby distinguished from S. rancho in which the embolus is difficult 
to see.
