Sphaenorhynchus
Scientists think the frogs in Sphaenorhynchus are closely related to the frogs in  Scarthyla and  Scinax. Faivovich and other scientists (2005) put Sphaenorhynchus in the group Dendropsophini. Dendropsophus, Lysapsus, Pseudis, Scarthyla, Scinax, and Xenohyla are in Dendropsophini too.
