A note on the karyotype and morphology of the ant Platythyrea sinuata (Roger, 1860) (Formicidae, Ponerinae, Plathytyreini

Patrícia Nayara Caldas Silva-Rocha, Joao Paulo Sales Oliveira Correia, Clea Santos Ferreira Mariano, Jacques Hubert Charles Delabie, Marco Antonio Costa


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.
