The diploid chromosome number of Leptagrion macrurum (Burnt.) from the surroundings of Sao Paulo (Brasil), 2 n d = 30, is the highest ever found in a dragonfly. Coupled with the neo-XY sex determination, it indicates the secondary nature of the karyotype. In Figure 2 a tentative model of the karyotypic evolution leading to the present peculiar situation is given. The cytotaxonomic evidence seems to be in favour of an ischnurine rather than pseudagrionine affinity of the Leptagrion alliance.
