Subfamily Scinaxinae New Subfamily

Scinaxinae . Type genus: Scinax Wagler, 1830 .

Definition. Small to medium-sized frogs with sacral diapophyses not expanded; in dorsal view, snout acutely rounded to acute with projecting proboscis.

Content. Four genera and 126 species.

Distribution. Mostly South America from Uruguay, northern Argentina, and northwestern Peru northward through Central America to southern and eastern Mexico; Islands of Tobago, Trinidad, and Saint Lucia. Etymology. The familial name is derived from the Greek skinos meaning quick or nimble, an appropriate name for these agile frogs.

Remarks. The support value is high (97%) for the cluster of three of the genera ( Julianus, Ololygon, and Scinax), but the placement of Sphaenorhynchus as the sister taxon of the others is low (49%); thus, the relationships of Sphaenorhynchus are equivocal.
