ABSTRACT. The monotypic bat genera Platalina and Tomopeas are rare and known from few localities through- out their distributions. These species have not been recorded in the northern half of their distributions for the last 4 and 3 decades, respectively, suggesting local extirpation. Here we present new records for both taxa from a 2012 expedition conducted in the northern end of their distributions. We suggest a role the oil concessions in the area can play towards the conservation of these two unusual bat species, as well as additional actions that will help to protect them.
RESUMEN. Nuevos registros de Platalina genovensium (Chiroptera, Phyllostomidae) y Tomopeas ravus (Chiroptera, Molossidae). Las especies de los géneros monotípicos Platalina y Tomopeas son raras y conocidas solo de pocas localidades a lo largo de su distribución. Estas especies no han sido registradas en el norte de su distribución en las últimas 4 y 3 décadas, respectivamente, sugiriendo una extinción local. Aquí se presentan nuevos registros obtenidos en una expedición realizada el 2012, en el norte de la distribución de ambas especies. Se destaca el papel de las concesiones petroleras ubicadas en el área para la conservación de estas dos especies de murciélagos únicas y también recomendamos medidas adicionales que ayudarán a protegerlas.
