Diagnosis. — A microhylid having a concealed tympanum and 

 lacking clavicles, procoracoids, and palatines. 



The absence of the clavicles and procoracoids separates this species 

 from Relictivomer pearsei, Otophryne robusta, and Elachistocleis ovalis, 

 while the absence of the palatines separates it from Glossostoma 

 aterrimum. 



Description. — MHNP 03-84 (holotype), from Rio Sarare, Norte de 

 Santander, Colombia. A microhylid without vomerine teeth; small, 

 rounded choanae; tongue three-fourths as wide as mouth opening, 

 pointed anteriorly, with well-developed cornua on each angle poste- 

 riorly, the cornua being free, a transverse row of glandular structures 

 across roof of mouth. Snout small, triangular when viewed from 

 above, broadly pointed in profile, the upper jaw extending beyond 

 lower; nostrils more lateral than superior, not projecting, their dis- 

 tance from end of snout about two-thirds that from eye, separated 

 from each other by an interval equal to their distance from eye. 

 Can thus rostralis hardly defined; loreal region concave and more 

 flattened than oblique, the upper lip flaring out, then rolling in below
