Different populations of Pseudonannolene strinatii Mauriès, 1974 collected from three caves in Iporanga, state of S o Paulo, were cytogenetically compared using techniques of conventional coloration, C-banding and silver nitrate impregnation. Specimens were morphologically similar and small cytogenetic differences were observed between the populations with relation to the distribution of constitutive heterochromatin. Diferentes popula es de Pseudonannolene strinatii Mauriès, 1974 coletadas em três cavernas em Iporanga, Estado de S o Paulo, Brasil foram comparadas citogeneticamente utilizando-se técnicas de colora o convencional, bandamento C e impregna o com nitrato de prata. Indivíduos demonstraram-se morfologicamente similares e diferen as citogenéticas sutis foram observadas entre as popula es com rela o à distribui o da heterocromatina constitutiva.
