As an endangered species in Thailand, wild animal species of the subfamily Paradoxurinae were selected for a cytogenetic study. The animal species sampled are Masked palm civet (Paguma lavata), Binturong (Arctictis binturong), Asian palm civet (Paradoxurus hermaphroditus) and Small-toothed palm civet (Arctogalidia trivergata). Blood samples taken from Khao Khiew Zoo, Songkhla Zoo and Dusit Zoo were examined using lymphocyte culture techniques. The results indicate that the number of diploid chromosome of Masked palm civet, Binturong, Asian palm civet and Small-toothed palm civet are 44, 42, 42 and 40, respectively. The fundamental number (NF) are 62, 46, and 50 for both male and female Masked palm civet, Binturong, Asian palm civet, while that of Small-toothed palm civet is 56 for female and 55 for male. The type number of autosomes, metacentric, submetacentric, acrocentric and telocentric chromosome are 6-10-10-16, 2-4-16-18, 2-4-20-14, and 6-8-10-14, respectively. Chromosome pairs 17, 19, and 20 are satellite chromosomes. The X and Y chromosomes are large submetacentric and small submetacentric for the Masked palm civet, whereas the Binturong and Asian palm civet have large metacentric and small submetacentric. The Small-toothed palm civet contains large metacentric and small acrocentric chromosome. In addition, conventional staining and G-banding techniques show that there are differences in number and location of G-banding for each species.
