【 摘 要 】

In this work, we present cytogenetic data for the land planarian Dolichoplana carvalhoi. Two different karyotypes, one diploid (2n = 2x = 14 chromosomes) and one triploid (2n = 3x = 21 chromosomes), corresponding to two morphological body patterns, are described. Chromosomes from regenerating blastema were studied after routine Giemsa staining and CBG banding. Our analyses revealed heteromorphisms in chromosomes 2, 3 and 4 of the diploid karyotype and in chromosomes 1, 3 and 7 of the triploid karyotype. Further studies are needed in order to determine if the two morphological patterns of D. carvalhoi represent distinct species.
