Diagnosis. — A moderate-sized, short-legged Hyla with just a trace 

 of web at base of fingers and with distinct black and white markings 

 on posterior face of thighs. 



The closest relative of H. rubra in Colombia, and the ones with 

 which it is most likely to be confused, are H. boulengeri and H. 

 joliamorta. From both of these it may be distinguished by its smaller 

 size and the fact that the black markings on the face of the thigh are 

 in the form of vermiculations rather than broad, vertical dark bands. 



Description. — CNHM 81818, from Mariquita, Tolima, Colombia. 

 Vomerine teeth in two short, rounded series, lying close together 

 between the small, rounded choanae; tongue three-fourths as wide 

 as mouth opening, broadly rounded, its posterior border slightly free 

 and almost imperceptibly notched. Snout moderate, flat, somewhat 

 pointed when viewed from above, broadly pointed in profile, the upper 

 jaw extending considerably beyond lower; nostrils between lateral 

 and superior, very slightly projecting, their distance from end of snout 

 about one-half that from eye, separated from each other by an interval 

 nearly equal their distance from eye. Canthus rostralis slightly de- 

 fined; loreal region rounded and somewhat oblique, the upper lip 

 flaring out below it. Eye moderate, prominent, its diameter equal to 

 its distance from nostril; palpebral membrane not reticulate; inter- 

 orbital distance about equal to width of upper eyelid, which is rela- 

 tively wide and slightly greater than distance between nostrils. 

 Tympanum very distinct, about one-half the diameter of eye, sepa- 

 rated from eye by a distance equal to one-third its own diameter. 

 Fingers with a trace of web at base, fourth finger considerably longer 

 than second, just reaching to disk of third which covers about one-half 

 the tympanic area; no projecting rudiment of a pollex; no ulnar ridge. 

 Toes slightly more than one-half webbed, the web on fourth toe 

 reaching nearly to base of the penultimate phalanx, third and fifth 

 toes subequal, disk of fourth toe covering about one-third the tympanic 

 area; a distinct oval inner and a much smaller but distinct rounded 

 outer metatarsal tubercle; no tarsal ridge; no dermal appendage on 

 heel. Body not elongate, in postaxillary region a little broader than 

 greatest width of head; when hind leg is adpressed, heel reaches 

 anterior margin of eye; when limbs are laid along the side, knee and 

 elbow fail to meet; when hind legs are bent at right angles to body,
