These areas represent localities where the taxonomic composition of the bat communities&lt;br/&gt;was relatively well known. We conducted field surveys using the Anabat II detector and analysis system. We&lt;br/&gt;compared acoustic inventories with previous lists obtained with conventional sampling methods (principally&lt;br/&gt;mist nets). We identified 30 species acoustically (representing 15 genera of the families Emballonuridae,&lt;br/&gt;Noctilionidae, Mormoopidae, Vespertilionidae, and Molossidae) on the basis of vocal signatures. Nineteen of&lt;br/&gt;these were verified by capture and subsequent recording of released animals; the remainder were identified by&lt;br/&gt;comparison with verified vocalizations from other localities. An additional 11 unidentified but distinct taxa&lt;br/&gt;were recorded and are referred to here as 'sonotypes' (based on similarities in call structure to known species)&lt;br/&gt;representing eight genera of the families Emballonuridae, Vespertilionidae, and Molossidae. The short-term&lt;br/&gt;acoustic surveys nearly equaled or exceeded the known species richness at three ofthe four localities, and added&lt;br/&gt;two to nine species to previous lists from all locations; many of these bats correspond to taxa difficult to detect&lt;br/&gt;with conventional capture methods.</style></abstract></record></records></xml>
