ABSTRACT

Pseudonannolene tocaiensis, sp.n. is described from Brazil, São Paulo, Itirapina. The karyotypes of P. tocaiensis, sp.n. and P. strinatti Mauriès, 1974 are also presented, both species are found in cave environments. P. tocaiensis has 2n=20, XY and P. strinatti, 2n=16; it was not possible to observe the sex determination mechanism in the latter.

Key words: Diplopoda, Pseudonannolene, cave millipedes, cytogenetic, millipedes
