In June of 1964, field parties from the Museum of Natural History, the University of Kansas, collected two specimens of a unique free-tailed bat in Mexico, one in the state of Guerrero and the other in Oaxaca. These proved to be the first specimens of Molossops greenhalli taken outside of Trinidad and the first bats of the genus to be reported from north of Panama. Subsequently, Percy L. Clifton obtained, in the state of Jalisco, three more individuals of M. greenhalli, including the first male from the North American mainland.
Comparison with material from Trinidad indicates that the Mexican bats represent a distinctive subspecies, which is named and described.
