Diseases that result in a regional loss of both species richness and genetic diversity highlight the importance of managing and building upon natural history collections. Occurrence data and specimen vouchers can supplement information regarding distribution and genetic diversity prior to the potential expansion into Texas of the emerging disease known as white-nose syndrome. Herein, six species of bats from 13 counties in Texas are reported. A total of 10 new county records were documented for four species (Myotis velifer, Perimyotis subflavus, Eptesicus fuscus, and Corynorhinus townsendii). Noteworthy winter observations were recorded for two additional species (Myotis austroriparius and C. ra nesquii). In addition to documenting occurrence records of bat species in the state of Texas, the first voucher specimens are provided from three sites positive for Pseudogymnoascus destructans, the causative agent of white-nose syndrome.
