Smith and Taylor (1948) recognized seven species of the genus in eastern Mexico. Firschein revised the eastern complex (as then understood), and in so doing added one new species and treated _Syrrhophus verruculatus_ as a _nomen dubium_. Dixon (1957) redefined the related genus _Tomodactylus_ and transferred _T. macrotympanum_ Taylor to the genus _Syrrhophus_. Neill (1965) described a new subspecies of _S. leprus_ from British Honduras. Two species (_S. gaigeae_ and _S. marnockii_) were recognized in Texas until Milstead, Mecham, and McClintock (1950) synonymized _S. gaigeae_ with _S. marnockii_. Thus, at present, nine species (one polytypic) are recognized on the eastern slopes and lowlands from central Texas to British Honduras. These are currently placed on one species group equivalent to the western complex reviewed by Duellman (1958).
