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 only small morphological differences. Nucleolar organizing region and C-band patterns are shown for H. brasiliensis. Citing Literature Volume82, Issue3March 1995Pages 369-375 RelatedInformation
