A Review of the Small Fruit Bats (Genus Artibeus) of Middle America

Part II concludes this review. Part I appeared in The South- western Naturalist 14(1): 15-29. Geographic variation and speciation in Ar- tibeus watsoni Thomas and Artibeus phaeotis (Miller) are discussed. The close relationship of A. watsoni and Artibeus glaucus Thomas is emphasized as is their distinctness from Artibeus cinereus Gervais. Three subspecies of A. phaeotis are recognized in Middle America, as follows: A. p. phaeotis in the Gulf-Caribbean versant from Veracruz to Panama; A. p. nanus in the lowlands of western Mdxico from Sinaloa to the Isthmus of Tehuantepec; A. p. palatinus, herein described as a new subspecies, in the Pacific lowlands from the Isthmus of Tehuantepec at least to the Rio Jorco east of Puntarenas, Costa Rica.
