Engystomops
''Engystomops'' is a genus of frogs in the family Leptodactylidae. They are commonly known as foam frogs or túngara frogs, though the latter name most commonly refers to ''Tungara frog, Engystomops pustulosus''. They are native to the Americas from southern Mexico south to the Amazon Basin. This genus was maintained on its own until 1970, when it was merged into ''Physalaemus'', a genus of similar frogs. As studies progressed, there was increasing evidence that ''Physalaemus'' was not a monophyletic group; it was made up of several groups. One of those groups consisted of several frogs more closely related to each other than to the rest of the ''Physalaemus'', and they were represented by ''P. pustulosus'', now ''Engystomops pustulosus''. This group was split off in 2005 on the basis of characters such as basic morphology (biology), morphology and animal communication, vocalizations, as well as Alloenzyme, allozyme and other genetic analysis. The group was given the revalidated n ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Engystomops Petersi
''Engystomops petersi'' (common name: Peters' dwarf frog) is a species of frog in the family Leptodactylidae. It is found in Amazon rainforest, Amazonian Colombia, Ecuador, and Peru. It is morphologically similar to its sibling species, ''Engystomops freibergi'', and for a period the latter was considered to be a Synonym (taxonomy), junior synonym of ''Engystomops petersi''. Taxonomy and classification of this species is constantly changing due to the continual evolution of behavioral isolation and rapid speciation in the region. There are also records from the Guianas that have not yet been allocated to either species. Genetic divergence, Divergence of these two species seems to have been driven by behavioural isolation related to Sexual selection in frogs#Vocal signaling, male call characteristics more than geographic isolation. Taxonomy The genus ''Engystomops'' is part of the family Leptodactylid. Previously, the genus ''Engystomops'' was grouped in with other Amazonian genera ...
