Cytogenetic analysis of the Formosan pangolin, Manis pentadactyla pentadactyla (Mammalia: Pholidota) Zoological Studies 46(4): 389-396. We analyzed the karyotypes of the Formosan pangolin, Manis pentadactyla pentadactyla, a subspecies of the Chinese pangolin, Manis pentadactyla. Pangolins belong to the mammalian order Pholidota and are primarily anteaters. Since eutherian Sry is highly conserved , we first conducted gene mapping of pangolin Sry by means of cross-species fluorescence in situ hybridization (FISH). The existence of a homologous Sry gene in the pangolin Y chromosome is demonstrated. We also report karyotyping by G- banding, C-banding, and Ag-NOR staining. The 2N and FN numbers of the Formosan pangolin are 40 and 70, respectively , which agree with the numbers reported for the subspecies Manis pentadactyla aurita from the Asian mainland. However, we found 2 or 4 nucleolar organizer regions (NORs ) in the Formosan pangolin, whereas the Chinese pangolin has 3 or 4. An ideogram for this species is proposed.
