| Comment | Synonymy: Entiauspe-Neto et al. 2021 synonymized P. cerradensis with P. concolor. P. concolor is distinguishable from other species of the group by the presence of an anterior temporal plate, higher ventral counts (224 ventrals), and uniform dorsal colouration. Mildly venomous. This species was described on the basis of a single female, and is now known from only four specimens (Entiauspe-Neto et al. 2021). |
| Etymology | O epíteto específico “cerradensis” é um adjetivo latinizado, significando “que ocorre no Cerrado”, referindo-se ao bioma no qual a nova espécie foi descoberta. |
