1823. Diphylla ecaudata Spix, Simiarum et vespertilionum Brasiliensium ..., p. 68, type locality, Brazil, restricted to Rio San Francisco, Baía, by Cabrera (Rev. Mus. Argentino Cien. Nat., 4:94, March 27, 1958).
Distribution in Tamaulipas.—Southern and central parts of state.
The hairy-legged vampire was first reported from Tamaulipas by de la Torre (1954:114), who recorded a male from five miles northeast of Antiguo Morelos, near El Pachón. Later in the same year Martin and Martin (1954:585) listed another male from El Pachón. Subsequently, Malaga and Villa (1957:543) reported specimens from two additional localities in the state, one of which (Cueva de la Sepultura) provides the northernmost place from which the species has been recorded. Malaga and Villa remarked that the species was abundant at Cueva de la Sepultura, being found in small groups clinging to the roof of the cave. Two females taken there on November 11 carried one embryo each; a lactating female was taken on November 14. The vampire, Desmodus rotundus, also was taken at Cueva de la Sepultura.
I follow Burt and Stirton (1961:37) in treating Diphylla ecaudata as a monotypic species.
Records: Cueva de la Sepultura, 7.5 km. NNW and hence 7 km. SSW (via highway) Cd. Victoria (Malaga and Villa, 1957:543); 5 mi. NE Antiguo Morelos, near El Pachón (de la Torre, 1954:114); El Pachón (Martin and Martin, 1954:585); Cueva de Quintero, 4 km. SSW Quintero (Malaga and Villa, 1957:543).

Distribution in Tamaulipas.—Central and southwestern parts of state.
All specimens examined were obtained from caves. At Cueva la Esperanza, approximately 400 individuals were found along with individuals of Desmodus rotundus; Natalus and Desmodus also were collected together in a cave approximately 30 yards deep three miles south and 14 miles west of Piedra, and in a cave six and a half miles north and 13 miles west of Jiménez, the northernmost locality from which N. stramineus is presently known.
