Mount Tucuche Tree Frog

F. fitzgeraldi snout–vent length is typically in the range of 16.1–18.3 mm (0.63–0.72 in) for males and 19.6–23.0 mm (0.77–0.91 in) for females, about 25.7% and 26.6% smaller, respectively, than the typical snout–vent lengths of Flectonotus pygmaeus, the only other species of Flectonotus. F. fitzgeraldi have rounded snouts, smooth tarsi and smooth backs. Females carry their eggs in a dorsal pouch, and the tadpoles have beaks with only small amounts of keratin and no denticles, and they hatch at an advanced stage of development.

F. fitzgeraldi is endemic to Trinidad and Tobago and the Venezuelan states of Sucre and Monagas. In Trinidad it can be found in the Northern Range, the southeast and down the centre-line of the island. In Tobago it can be found in the Main Ridge Forest Reserve. In Venezuela it can be found on the Paria Peninsula of Sucre, in area around the La Cernatana and Campeare mountains, also of Sucre, and in the Turimiquire Massif region on the border of Sucre and Monagas. It is an arboreal species occurring in various microhabitats of humid montane forest such as the leaf bases of bromeliads and aroids and in bushes, and it can be found at elevations of up to 1,000 m (3,300 ft). It is threatened by habitat loss. The species was formerly listed as endangered on the IUCN Red List.
