Abstract

We report the currently existing 31 records for Austral Patagonian and Fuegian bats spanning from 1866 to 2022. The Vespertilionidae were: Myotis chiloensis, Histiotus magellanicus, and Lasiurus varius, and the Molossidae was Tadarida brasiliensis. The former two species were recorded at forested sites along a swath that runs NW-SE for about 670 km from Torres del Paine in continental Magallanes to Tierra del Fuego and Navarino islands. Those forests were Coihue-Canelo (Nothofagus betuloides-Drymis winteri), Coihue-Lenga (N. betuloides-N. pumilio), Lenga (N. pumilio-Maytenus disticha), or Ñirre shrubland (N. antarctica-Chiliotrichum difussum). Only one record for each of Lasiurus varius, Histiotus magellanicus, and Tadarida brasiliensis were located in steppe environments of Festuca gracillima-Chiliotrichum difussum but were centered at human habitations and surrounding orchards or plantations, and their presence therein may be deemed accidental.
