1949. A[rtibeus]. l[ituratus]. palmarum, Hershkovitz, Proc. U. S. Nat. Mus., 99:447, May 10.
Distribution in Tamaulipas.—Tropical region in southern part of state.
Two specimens from the Río Sabinas were taken in a mist net placed across the small, crevicelike entrance to a cave. Ten pregnant females taken in late May each contained a single embryo; average crown-rump length of the 10 embryos was 43 (35-55) mm.
Tamaulipan specimens of lituratus do not differ appreciably in color from topotypes except that the facial stripes are narrow and, in three individuals, poorly marked. Lukens and Davis (1957:9) reported that females from Guerrero were paler than the males, but the male examined in this study does not differ in color from the females seen.
