Genus and sp. indet.
Records:
São Paulo state, Brazil; Oligocene (Deseadan); bituminous shales of Tremembé-Taubaté Basin, Tremembé Formation (Leonardos 1924; Mezzalira 1964, Mezzalira 1966; Mezzalira 1989).
Remarks:
A crushed partial skeleton and impression with small fragments of the teeth remaining (Museu Geológico Valdemar Lefevre no. 45-V of the Instituto Geológico (formerly IGG), São Paulo [image ]). It differs in its measurements from those of the holotype partial skeleton of Mormopterus faustoi from the same formation as given by Paula Couto (1956), and probably represents a different species. Some of the measurements (in mm) of 45-V are: head and body length, 56(estimated); humerus length, right 28.2, left 27.0; forearm, left 46, right 48; radius, left 44.5, right 46.2; ulna to point of fusion with radius, left 20.0, right 18.7(est.); thumb, right 5.5; femur, left 15.8(est.), right 16.2; tibia, right 18.3; foot length, 11(est.).
