Winge (1887) reported remains of multiple species, but it was not possible to safely determine them beyond the family level. Few recent skeletons were available for comparison and no exact matches were found for the humeri of Pyriglena leucoptera View in CoL and Formicivora rufa rufatra —thamnophilids then included in Formicariidae View in CoL (which indicates that the material under this determination may include more than one family). Two small humeri from Lapa da Escrivânia V are especially thin and delicate even for this family; they have the same length as observed in Troglodytes musculus , but the humerus of this species is relatively more robust.

Goeldi (1894) erroneously listed Pyriglena leucoptera as provisionally represented among the material.
