Smilisca baudini (Duméril and Bibron)
Chinajá, 9; 20 km. NNW of Chinajá, 42; Río de la Pasión, 1; Río San Román, 5; Sayaxché; Toocog, 2.
Individuals of this species were found at night sitting on bushes and small trees in the forest in February and March and again in June and July. One was in the axil of a leaf of a Xanthosoma. In June and July males were heard nearly every night. The series of specimens from 20 kilometers north-northwest of Chinajá was taken from a breeding congregation in a shallow muddy pool in the forest. Tadpoles of this species were in small, often muddy pools in the forest. To my knowledge Smilisca baudini is the only hylid to breed in these pools at Chinajá, although perhaps Smilisca phaeota also utilizes them. The only other amphibian at Chinajá known to breed in the pools is Bufo valliceps valliceps. Although two specimens were on bushes at night at Toocog, Smilisca baudini was not present at the pond where five other species of hylids were breeding. Nevertheless, Smilisca baudini was calling from two ponds on the savannas near La Libertad. All of the specimens from southern El Petén have yellow or yellowish white flanks and ventrolateral surfaces.
Smilisca phaeota cyanosticta (Smith)
Chinajá, 4; 10 km. NNW of Chinajá, 1.
