Two distinct groups were found. One group includes six species that showed high asymmetric bimodal karyotypes, while the second group has two species that have a karyotype similar to those observed in European species. All the species have karyotypes with 2n = 8 that are very uniform within each group, with onnly small morphological differences. Nucleolar organizing region and C-band patterns are shown for H. brasiliensis.  aCitogenética1 aRUAS, P. M.1 aMATZENBACHER, N. I.1 aROSS, G.1 aBERNINI, C.1 aVANZELA, A. L.
