Eleutherodactylidae

This taxon corresponds to Eleutherodactylidae of Hedges et al. (2008a). It includes the South American genera Adelophryne and Phyzelaphryne , the Middle American genus Diasporus , and the Antillean–Middle American genus Eleutherodactylus . This clade was discovered by Heinicke et al. (2007) and has been corroborated by Hedges et al. (2008a), Pyron & Wiens (2011), and Canedo & Haddad (2012). Hedges et al. (2008a) proposed as synapomorphic the absence of nuptial pads in males of this clade.

Hedges et al. (2008a) erected two subfamilies within Eleutherodactylidae , Eleutherodactylinae for Eleutherodactylus and Diasporus , and Phyzelaphryninae for Adelophryne and Phyzelaphryne . Previously, the only hypothesis suggesting a relationship between Phyzelaphryninae and Eleutherodactylinae was formulated by Frost et al. (2006), who noted that the conspicuously pointed tips on the toe discs would ally Adelophryne with Phyzelaphryne and the Eleutherodactylus diastema group (now Diasporus ).
