With the exception of Taylor (1952), who treated the Costa Rican species, none of these authors dealt with the present status of the nineteen species erroneously assigned to Syrrhophus. These species are listed in Tables [1] and [2] with the name currently applied. Some of them are new combinations and their justifications will be published elsewhere. Gorham (1966) is the most recent author to include South American species in the genus Syrrhophus.
Smith and Taylor (1948) recognized two species groups of the genus in México, an eastern and a western group (here termed complexes for purposes of discussion), separated on the basis of the number of palmar (metacarpal) tubercles (three palmar tubercles in the members of the eastern complex and two in those of the western complex). Duellman (1958) reviewed the species of the genus occurring in western México and concluded that there were five species (two polytypic). Dixon and Webb (1966) described an additional species from Jalisco, México. The distributions of some species have been extended, but otherwise the western complex of species remains unchanged since Duellman's review.
Smith and Taylor (1948) recognized seven species of the genus in eastern México. 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).
