marginata and H. albopunctulata of Colombia, H. rujitela of Panama

 following key: 



a 1 . Tympanum about one-fourth the diameter of eye; vomerine teeth in two 

 small transverse series : ; H. albpunctulata 



a 2 . Tympanum about one-half the diameter of eye; vomerine teeth in two 

 moderate-sized, somewhat arched series H. albomarginata

Diagnosis. — A Hyla with ulnar and tarsal ridges, a small, triangular 

 dermal appendage on heel, and practically no dorsal pattern (nearly 

 pure white in preservative but with bright pink webbing on hands and 

 feet in life). 



The nearly pure white dorsum in combination with ulnar and 

 tarsal ridges and dermal heel appendages set H. albomerginata apart 

 from all Colombian frogs except H. albopunctulata, from which it 

 differs in its larger tympanum and more strongly developed vomerine 

 teeth. 



Description. — CJG 2354, from Zetaquira, near Miraflores, Boyaca, 

 Colombia. Vomerine teeth in two somewhat arched series, lying close 

 together just slightly behind the posterior borders of the moderate- 

 sized, rounded choanae; tongue three-fifths as wide as mouth opening, 

 broadly rounded, its posterior border fused and somewhat truncate
