Taxonomic status and redescription of Flectonotus ulei (Anura: Hemiphractidae), with a key for the species of Fritziana

ABSTRACT

Based on preserved specimens from the states of São Paulo and Rio de Janeiro, Flectonotus ulei Miranda-Ribeiro, 1926 is resurrected from its synonymy with Flectonotus fissilis (Miranda-Ribeiro, 1920) and is redescribed. Analysis of osteological characters and brood pouch structure confirms that F. ulei belongs to Fritziana. The species is small for the genus (snout-vent length in males, 19.2-26.9 mm, n = 2; in females, 20.3-21 mm, n = 4) and was found in bromeliads. Flectonotus ulei is characterized by dorsal pattern consisting of interorbital pentagon or hexagon-shaped mark delimited by heavy dark line, diameter of tympanum smaller than that of disc of third digit, and a brood pouch covering the eggs dorsally except for a narrow longitudinal slit; eggs arranged in rosette.
