Sphaenorhynchus is a genus of frogs in the family Hylidae.[1][2] They are also known as lime treefrogs[1] or hatchet-faced treefrogs.[3] They are found in the Amazon and Orinoco River basins of South America, the Guianas, Trinidad, and southern and eastern Brazil.[1] The majority of the species are associated with the Atlantic Forest domain in Brazil.[4]
Systematics
Sphaenorhynchus has been suggested to be the sister taxon of the clade Scarthyla + Scinax.[1] Faivovich and colleagues (2005) placed it in the tribe Dendropsophini, together with Dendropsophus, Lysapsus, Pseudis, Scarthyla, Scinax, and Xenohyla.[5]
Description
Sphaenorhynchus are small to moderately sized frogs. They are bright green or yellowish green in life. The snout is pointed and projecting in lateral view. Most species have well-developed horizontal dermal flaps on each side of the anus. The fingers are weakly webbed while the toes are extensively webbed. Males have a vocal sac on the posterior throat region.[6]
