Chromosomal characterization of Pseudonannolene strinatii (Spirostreptida, Pseudonannolenidae)

Agari Campos, KleberS. Fontanetti, Carmem

The chromosomes of the cave millipede Pseudonannolene strinatii Mauriès, 1974 were investigated. The diploid chromosome number was found to be 2n=16, XX/XY; the C-banding technique revealed a large amount of heterochromatin while the silver staining technique (Ag-NOR) evidenced the presence of heteromorphism of the NORs in some cells.
