Karyotypes of four rats (Rodentia: Muridae) from Sulawesi (Celebes), Indonesia.

Karyotypes and information pertinent to genetic mapping of small mammals in remote areas of Southeast Asia are practically nonexistent. The diverse island complex of the Indo-Australian archipelago offers a unique situation to study the interrelationships of the taxonomically confused order Rodentia. Yosida (1969, 1971, 1973) reported karyotypes of two species of rodents from Makassar, located on the extreme southern tip of this Indonsian island. This report cites karyotypic infor mation of four species of rodents trapped in the remote central area around the Lake Lindu region. To date, and to the best of my knowledge, this is the first reporting of these taxa. The reader must also take into consideration the possibility of constant taxonomic revisions and, therefore, differences in the identifications of the species from the ones reported here.
