Generic level taxonomic confusions

Hydrophylax: This genus was described by Fitzinger (1843) to accommodate Rana malabarica (Tschudi, 1838), but was later synonymised with Rana by Günther (1859). Dubois (1992) resurrected Hydrophylax as a subgenus (subsection), for this taxon [Rana (Hydrophylax) malabarica] based on finger and toe tip morphology. It was later recognised as a genus based on further morphological and molecular evidence (Frost et al., 2006). However, Che et al. (2007) synonymised Hydrophylax with the genus Hylarana, based on molecular evidence. Interestingly most of the recent studies (Frost et al., 2006; Che et al., 2007; Bossuyt et al., 2006; Matsui et al., 2005) did not use the type species of this genus, while a few others that use Hylarana malabarica’ did not sample a population from within the type locality (Wiens et al., 2009; Pyron and Wiens, 2011).

Sylvirana: Dubois (1992) proposed this as a new subgenus, which was redefined and considered as a genus by Frost et al. (2006). Bossuyt et al. (2006) demonstrated that Hylarana is embedded within a paraphyletic Sylvirana, and subsequently Che et al. (2007) synonymised Sylvirana with Hylarana.
