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. © SAREM, 2013.
