The karyotype of Phlebotomus perniciosus with some observations on cytogenetics of Phlebotominae in relation to the other Psychodidae.

The karyotype of Phlebotomus perniciosus has been described. This consists of five pairs of chromosomes and includes a pair of heterosomes of XY type. Some observations on the karyotypic structure of Phlebotominae based on the comparison between Phlebotomus and Lutzomyia and between Phlebotominae and Psychodinae have been made, taking into account the taxonomical and karyological situation of the two groups.
