Perimyotis subflavus (F. Cuvier 1832)

American Perimyotis

The American perimyotis, Perimyotis subflavus , is a year-round resident of Texas ( Ammerman et al. 2012) and is common within the eastern half of the state ( Schmidly 2004). P. subflavus has been found in 10 physiographic regions within the state ( Ammerman et al. 2012) and is associated closely with riparian woodlands within the area ( Schmidly 2004). Waterways are highly utilized by this species ( Fujita and Kunz 1984). The species recently has been determined a resident of New Mexico ( Valdez et al. 2009) and Armstrong et al. (2006) suggested that it also is a resident of Colorado. Within Texas, recent records in Lubbock, Presidio, and Brewster counties ( Yancey et al. 1995; Schmidly 2004; Ammerman 2005) suggest that the species may be expanding its range westward. The addition of three new county records in the Panhandle from Moore, Potter, and Hutchinson counties support this expansion. However, Armstrong et al. (2006) speculated whether the individual specimens in Colorado represented an actual range expansion in recent decades or merely an extension of our knowledge of bat distribution in the state. Sixteen new Texas county records and one noteworthy occurrence for P. subflavus are presented herein.

(2005) previously reported a single specimen of P. subflavus at Stephen F. Austin State University (#3078) captured in 1974, but we were unable to locate this specimen. Therefore, our vouchers are not new county records, but instead provide additional verification of the occurrence of P. subflavus in Rusk County.
