Species Description: De la Riva I, Chaparro 2005 A new species of Hyla is described from cloud forests of the Cosnipata Valley in southern Peru. Amphibia-Reptilia 26(4): 515 - 521 Described as Hyla; DBW has temporarily lodged it in Hyloscirtus pending paper by de la Riva and Faivovitch.

Like other members of the genus Gastrotheca, female G. antoniiochoai bear a closed brood pouch. However, the brood pouch morphology is unusual; this species has a lateral, paired brood pouch, unlike most members of the genus Gastrotheca, in which females have a single dorsomedian brood pouch. Only three other Gastrotheca species with paired brood pouches are known: G. zeugocystis, from central Peru, plus G. walkeri and G. williamsonii, both from Venezuela (Catenazzi and Lehr 2009).
Dorsal coloration is brown to golden tan. Tiny darker spots and green spots are scattered dorsally from the interorbital region to the sacral area. Eyelids have narrow dark flecking along their length. A tan stripe runs laterally from the nostrils to the posterior margin of the cilia (on the eyes). No interorbital or T-shaped dorsal markings are present. No pale dorsolateral stripe is present. Flanks are beige with tiny dark brown spots. Venter is gray-brown or beige with many black melanophores.
Juvenile coloration differs somewhat from that of the adult. In juveniles, the limbs are barred. Also, in juveniles the dark tan band runs from the nares laterally all the way to the midbody, but with an interruption above the arm insertion. Further, juveniles have reddish-bronze irises with black reticulations, rather than bronze irises (Catenazzi and Lehr 2009).
Distribution and Habitat
Life History, Abundance, Activity, and Special Behaviors
This species is thought to be direct-developing, based on the size and number of eggs (Catenazzi and Lehr 2009), plus the fact that in other cloudforest Gastrotheca species, the embryos develop into froglets within the dorsal pouch (Duellman and Maness 1980; Wassersug and Duellman 1984). A female specimen had a total of six relatively large eggs within her lateral, paired brood pouches, with each egg measuring about 6.5 mm in diameter. Although the female was kept in captivity for some time, the eggs slipped out of the pouch and did not complete development, so it was not possible to directly observe whether a larval stage ensued (Catenazzi and Lehr 2009).
