Hyla rubeola, new species 



Plate 30a-c 



Holotype. — USNM 152751, collected on Serrania de La Macarena, 

 Meta, Colombia, January 4, 1959, by F. Medem. 



Diagnosis. — This new species, a member of the "green" Hyla group, 

 is allied to punctata and rhodoporus. It is characterized by having a 

 small tympanum set close to the eye, greatly reduced webbing on 

 the ringers, and (iD life) bright red, narrow, dorsolateral stripes and 

 scattered pepper-like spots of bright red on the back. 



It may be differentiated from punctata by having the red dorsal 

 markings as minute red flecks rather than as distinct rounded spots, 

 the tympanum separated from the eye by a distance equal to only one 

 fourth its own diameter, and a more slender build. From H. rhodoporus 

 it differs in its more slender build and the presence of dorsolateral 

 red stripes and the tiny fleck-like red specks on the back. 



Description of holotype. — Vomerine teeth in two series, lying close 

 together between the moderate-sized, oblong choanae; tongue one- 

 half as wide as mouth opening, broadly triangular, its posterior border 

 truncate and not at all free. Snout moderate, U-shaped when viewed 

 from above, truncate in profile, the upper jaw extending but slightly 

 beyond lower; nostrils nearly lateral, considerably projecting, their 

 distance from end of snout about one-fourth that from eye, separated 

 from each other by an interval equal to about one-half their distance 

 from eye. Canthus rostralis strongly defined; loreal region somewhat 

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

 not particularly prominent, its diameter equal to its distance from 

 nostril; palpebral membrane not reticulate; interorbital distance 

 slightly greater than width of upper eyelid, which is slightly greater 

 than distance between nostrils. Tympanum very distinct, about 

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

 nearly equal to one-fourth its own diameter. Fingers with but a trace 

 of web at base, fourth finger considerably longer than second, just 

 reaching to disk of third which covers about one-fourth the tympanic 

 area; no projecting rudiment of a pollex; no ulnar ridge. Toes less than 

 one-half webbed, the web on fourth toe reaching base of the antepe- 

 nultimate phalanx, third and fifth toes subequal, disk of fourth toe 

 covering about one-sixth the tympanic area; a distinct oval inner and 

 an equally distinct rounded outer metatarsal tubercle; no tarsal ridge; 

 no dermal appendage on heel. Body elongate, in postaxillary region 

 distinctly narrower than greatest width of head; when hind leg is 

 adpressed, heel reaches slightly beyond tip of snout; when limbs are 

 laid along the side, knee and elbow considerably overlap; when hind 

 legs are bent at right angles to body, heels fail to meet. No patagium. 

 Skin of upper parts smooth; a rather narrow glandular ridge passing
