Unexpected phylogenetic positions of the genera Rupirana and Crossodactylodes reveal insights into the biogeography and reproductive evolution of leptodactylid frogs.
The Rio Grande chirping frog (Syrrhophus cystignathoides campi) is a direct-developing leptodactylid, which accidentally has been introduced into San Antonio and Houston from its native Mexico and lower Rio Grande Valley, probably via potted plants (Dixon, 1987).
The Rio Grande chirping frog, Syrrhophus cystignathoides campi Stejneger, 1915, is a small leptodactylid anuran that ranges naturally from Cameron and Hidalgo counties of the lower Rio Grande valley of Texas southward to northeastern Mexico (Dixon, 1987; Conant and Collins, 1991).
spectans is known to infect the bufonids Rhinella crucifer (Wied-Neuwied, 1821), Rhinella icterica (Spix, 1824), and Rhinella schneideri (Werner, 1894) and the leptodactylid Leptodactylus latrans (Steffen, 1815) (Vicente et al., 1990).
