Abstract     
Callopsis Rhinoclemmys
The turtle genus Callopsis Gray occurs from northern Mexico southward to northern South America, and consists of four monotypic species (C. annulata, C. areolata, C. funerea, and C. nasuta, which is elevated from subspecific rank) and three polytypic species (C. pulcherrima, C. punctularia, and C. rubida). The subspecies of C. pulcherrima are C. p. pulcherrima, C. p. incisa, C. p. manni, and a new taxon, C. p. rogerbarbouri. The subspecies of C. punctularia are C. p. punctularia, C. p. diademata, and C. p. melanosterna. Callopsis rubida has two subspecies: C. r. rubida and C. r. perixantha. A key for identification, a description, and the geographical range are presented for all species and subspecies. The genus includes three groups based on shell morphology and color, and on figure patterns of the head, carapace, plastron, and bridge: (1) the pulcherrima-rubida group of terrestrial turtles; (2) the punctularia group of aquatic and terrestrial species (including C. annulata, C. funerea and C. nasuta); and (3) C. areolata, of uncertain relationships. The similarities and differences within each group are discussed, and a hypothesis on the radiation within the genus is presented. The form Rhinoclemmys lunata Gray, 1873, is synonymous with Rhinoclemys bellii Gray, 1863, and both are only head pattern variants of Testudo punctularia Daudin, 1802 [= Callopsis p. punctularia].
