Crossodactylodes
Crossodactylodes is a South American genus of frogs and toads of the family Leptodactylidae. Because of their uncertain familial position among the South American frogs, the species was last molecular genetics examined in 2013 and by the family Cycloramphidae into which they had been placed in 2006, again transferred to the Leptodactylidae family.
Features
The genus is characterized by its widened fingers and toes and by the hidden tympanum (outer membrane of the ear ). A key feature of the genus, which has not yet been specified by Doris Mable Cochran in their first description of the type species Crossodactylodes pintoi in 1938, the horny spine formation at the thumb of the male. Only in 1955 mentioned Doris Mable Cochran these thorns in their study Frogs of Southeastern Brazil.
Dissemination
The genus is endemic to the highlands of the Atlantic rainforests of Brazil. The distribution area covers parts of the states of Rio de Janeiro, Espírito Santo, Minas Gerais and Bahia in southeastern Brazil.
Way of life
The frogs of the genus Crossodactylodes spend their entire life cycle in the water-filled funnels of bromeliads.
Taxonomy and systematics
2013, the subfamily Crossodactylodinae was built within the family Leptodactylidae for Crossodactylodes and the closely related genera Rupirana, Paratelmatobius and Scythrophrys. However, this name is not valid, since as early as 2012, a similar group was described under the name Paratelmatobiinae.
Species
Beginning of 2014 were described five types:
- Crossodactylodes bokermanni Peixoto, 1983
- Crossodactylodes Itambe Barata, Santos Leite & Garcia, 2013
- Crossodactylodes izecksohni Peixoto, 1983
- Crossodactylodes pintoi Cochran, 1938
- Crossodactylodes septentrionalis Teixeira, Recoder, Amaro, Damasceno, Cassimiro & Rodrigues, 2013
