Diagnosis. — A centrolenid without vomerine teeth, with a web 

 between fingers 2 and 3 and a well-developed web between fingers 

 3 and 4, and with no sharp line of demarcation between the dorsal 

 and ventral ground color. 



This species may be distinguished from all Colombian centrolenids 

 except buckhyi, fleischmanni and johnelsi by the absence of vomerine 

 teeth. From buckleyi it may be distinguished by the more extensive 

 webbing between the toes and the more prominently developed 

 humeral spine. From fleischmanni it differs in having the dorsum 

 heavily pigmented. From johnelsi it differs in lacking the numerous 

 spiny wart-like protuberances on the dorsal surfaces. 



Description. — AMNH 1353, from Santa Rita Creek, 14 miles north 

 of Mesopotamia, Antioquia, Colombia. Vomerine teeth absent; 

 choanae small, rounded, separated by a distance about five times 

 their own diameters, tongue two-thirds as wide as mouth opening, 

 broadly rounded, its posterior border free and shallowly notched. 

 Snout short, rounded when viewed from above, truncate and slightly 

 sloping in profile, the upper jaw extending but slightly beyond lower; 

 nostrils more lateral than superior, not projecting, their distance 

 from end of snout about one-half that from eye, separated from each 

 other by an interval equal to about their distance from eye. Canthus 

 rostralis slightly defined; loreal region slightly concave and somewhat 

 oblique, the upper lip flaring out slightly below it. Eye moderate, 

 rather prominent, its diameter one-third as great as its distance from
