Taxonomic Notes
Oliveira & Feitosa (2019) - There is a record of a single individual of P. brujitae in Bahia, Brazil (Nascimento et al. 2004). However, after careful examination of the specimen, we concluded it actually corresponds to a different and undescribed species. We refrain from describing it since the only known specimen is in very poor condition.
