1897. Lasiurus borealis teliotis, Miller, N. Amer. Fauna, 13:110, October 16.
Distribution in Tamaulipas.—Generally distributed in higher parts of state.
Eight June-taken females, all lactating, from the Sierra de Tamaulipas averaged 10.0 (8-12) grams; five males from there weighed 9.2 (8-10) grams. According to Hall and Kelson (1959:188), males of this species usually are more brightly colored than females but this phenomenon is not evident in the Tamaulipan specimens. Males do, however, average slightly smaller than females.
The name Lasiurus borealis teliotis is employed following Handley (1960:472); formerly L. b. ornatus Hall was applied (Hall and Kelson, 1959:190) to bats here referred to as teliotis.
