cytotaxonomy, CMA3/DAPI, Chromosomal heteromorphism, Phenotypic


The taxonomic status of Platythyrea is still confused because there is high phenotypic plasticity, possible taxonomic synonyms and morphological proximity with other species of the same genus. The correct identification of Platythyrea sinuata depends on interdisciplinary analyzes with a morphological and genetic approach. Here we provide the description of karyotype for P. sinuata, 2k=24M+20A with CMA3+/DAPI- on single chromosome. This data will be helpful to the understanding of the taxonomic status of this species.
