Diagnosis. — A moderate-sized tree frog with the palpebral mem- 

 branes reticulate, a spur-like dermal appendage on the heel, and the 

 fingers about one-half webbed. 



This subspecies may be distinguished from all Colombian Hyla 

 except H. maxima by the reticulations on the palpebral membranes. 

 It may be readily distinguished from H. maxima by the much larger 

 appendage on the heel and by having the fingers only one-half webbed. 

 In the structure of the dermal heel appendage it is most like Hyla 

 calcarata, but it differs from that species in having the palpebral 

 membranes reticulate and in having the fingers about one-half webbed 

 rather than with just a trace of web. 



Description. — MLS 64, an adult female from Guaicaramo, Boyaca, 

 Colombia. Vomerine teeth in two heavy angulate series which touch 

 on the midline and lie between the large, oblong choanae; tongue 

 three-fourths as wide as mouth opening, broadly cordiform, its 

 posterior border fused and very shallowly notched. Snout moderate, 

 broadly triangular when viewed from above, somewhat truncate 

 in profile, the upper jaw extending slightly beyond lower; nostrils 

 more lateral than superior, considerably projecting, their distance 

 from end of snout about one-third that from eye, separated from 

 each other by an interval equal to about two-thirds their distance 

 from eye. Canthus rostralis well defined; loreal region concave and 

 oblique, the upper lip flaring out rather strongly below it. Eye not 

 large, nor particularly prominent, its diameter equal to its distance 

 from nostril; palpebral membrane reticulate; interorbital distance 

 half again as great as width of upper eyelid, which is only slightly 

 greater than distance between nostrils. Tympanum very distinct, 

 about three-fifths the diameter of eye, separated from eye by a 

 distance about equal to one-third its own diameter. Fingers more 

 than one-half webbed, the web reaching base of the penultimate 

 phalanx of the fourth finger on the lateral side and extending thence 

 as a narrow margin on the medial side; fourth finger considerably 

 longer than second, just reaching to middle of disk of third which 

 covers about two-thirds the tympanic area; no projecting rudiment 

 of a pollex; a distinct ulnar ridge. Toes three-fourths webbed, web on 

 fourth toe reaches base of penultimate phalanx, on all other toes 

 it reaches to base of disk; third and fifth toes subequal, disk of fourth
