| Abstract |
|
Analyses of meiotic and mitotic chromosomes are presented for eight species of Neotropical turtles. Geochelone carbonaria differs from G. denticulata by centromere position of one of the smaller macrochromosomes. Geochelone carbonaria is considered primitive in this respect because its karyotype is similar to that of the Old World batagurines. Three taxa of Greater Antillean Chrysemys (C. terrapen, C. stejnegeri vicina, C. decorata) possess a typical emydine karyotype and do not differ from other Chrysemys or other emydine genera that have been karyotyped. Rhinoclemys punctularia has two pairs of microchromosomes that are not found in R. pulcherrima. Rhinoclemys punctularia is considered to be karyotypically primitive to R. pulcherrima due to its closer similarity to the Old World batagurine karyotype. The karyotype of Kinosternon scorpioides from Trinidad is similar to previous reports of specimens from Brazil and of other species of Kinosternon.
