“…Such a hypothesis is consistent with the evidence for low levels of recent migration, historical directional dispersal from the Little Bahama Bank to the Great Bahama Bank, high levels of population differentiation, and lack of morphological overlap between Great Bahama Bank Tadarida and the northern population sampled from the Little Bahama Bank and Florida. It has previously been suggested based on limited morphological sampling that Caribbean populations of Tadarida brasiliensis are distinct from those on the mainland and that individuals in The Bahamas represent a unique subspecies— T. b. bahamensis (type specimen collected from Governor's Harbor, Eleuthera, and preserved at the University of Pennsylvania; Rehn, ; Shamel, ; Schwartz, ). Future studies should include better sampling of other islands in the Caribbean and mainland individuals, especially from South America, to better assess the possibility of a Caribbean species in the genus Tadarida .…”

“…Vectors pointing toward the PC2 axis represent skull measurements, and the single vector pointing to the PC1 axis is the forearm measurement. Discriminant function analysis (right) also shows differentiation between the Great and Little Bahama Bank, with the exception of one individual from the Little Bahama Bank et al, 2016; Russell & McCracken, 2006 and preserved at the University of Pennsylvania; Rehn, 1902;Shamel, 1931;Schwartz, 1955). Future studies should include better sampling of other islands in the Caribbean and mainland individuals, especially from South America, to better assess the possibility of a Caribbean species in the genus Tadarida.…”

Dispersal is a driving factor in the creation and maintenance of biodiversity, yet little is known about the effects of habitat variation and geography on dispersal and population connectivity in most mammalian groups. Bats of the family Molossidae are fast‐flying mammals thought to have potentially high dispersal ability, and recent studies have indicated gene flow across hundreds of kilometers in continental North American populations of the Brazilian free‐tailed bat, Tadarida brasiliensis. We examined the population genetics, phylogeography, and morphology of this species in Florida and across islands of The Bahamas, which are part of an island archipelago in the West Indies. Previous studies indicate that bats in the family Phyllostomidae, which are possibly less mobile than members of the family Molossidae, exhibit population structuring across The Bahamas. We hypothesized that T. brasiliensis would show high population connectivity throughout the islands and that T. brasiliensis would show higher connectivity than two species of phyllostomid bats that have been previously examined in The Bahamas. Contrary to our predictions, T. brasiliensis shows high population structure between two groups of islands in The Bahamas, similar to the structure exhibited by one species of phyllostomid bat. Phylogenetic and morphological analyses suggest that this structure may be the result of ancient divergence between two populations of T. brasiliensis that subsequently came into contact in The Bahamas. Our findings additionally suggest that there may be cryptic species within T. brasiliensis in The Bahamas and the West Indies more broadly.

“…Shamel (1931) added material from Guadeloupe, Antigua, and Puerto Rico to the monotypic species and continued to distinguish the taxon based on its small size. Finally, Schwartz (1955) reduced this monotypic species to subspecific rank within the widespread mainland species Tadarida brasiliensis, which is the arrangement that we have followed.…”

“…This was another species in which considerable variation in color was noted, one extreme being brownish gray, the other a dark gray without a trace of brown. We follow Allen (1911) and Schwartz (1955) in considering bahamensis a subspecies of T. brasiliensis, since all the members of the brasiliensis group are allopatric and very similar, more so than are any of the sympatric American species in the subgenus Tadarida.…”
