This chapter observes that the genus Micronycteris has undergone several taxonomic changes in recent years. It notes that the most recent morphological review of Micronycteris recognizes nine species, including four dark-bellied species (hirsuta, matses, megalotis, microtis), and five pale-bellied species (brosseti, homezi, minuta, sanborni, schmidtorum). The chapter observes that specimens of Micronycteris from Ecuador are poorly represented in museum collections, and that some important areas within the country have few voucher specimens. It assesses the morphological and molecular interspecific variation within the genus, comparing its series to other Micronycteris found in Ecuador and other Latin American countries. The chapter distinguishes three morphotypes among dark-bellied forms. It provides a set of characters useful to distinguish dark-bellied species of Micronycteris in Ecuador and describes a new species.
