Remarks. Carvalho (1989) presents a redescription of P. pampiana .

Biology. Some studies show the association of this species with the carcass decomposition of little rodents ( Moura et al. 1997) or with nest of Furnarius rufus (Gmelin) (Aves: Furnariidae ) ( Turienzo & Di Iorio 2010). The specimens captured by the authors were collected on decaying beef liver, chicken viscera, and dog faeces.
