Occurrence of Sturnira tildae De La Torre, 1959 (Chiroptera: Phyllostomidae) in the state of Maranhão, Brazil
The bat genus Sturnira is widely distributed in the Neotropical region, from northwestern Mexico to northern Argentina, and four species occur in Brazil: Sturnira lilium, Sturnira giannae, Sturnira magna, and Sturnira tildae. The present study is the first to record Sturnira tildae in the state of M...

| Sumario: | The bat genus Sturnira is widely distributed in the Neotropical region, from northwestern Mexico to northern Argentina, and four species occur in Brazil: Sturnira lilium, Sturnira giannae, Sturnira magna, and Sturnira tildae. The present study is the first to record Sturnira tildae in the state of Maranhão, Brazil, based on morphological and molecular diagnoses. The specimen was identified based on its cranial and morphometric traits. The diagnostic traits include discreetly bilobed inner upper incisors with a broad base, lower first and second molars with lingual cusps separated by shallow grooves, and forearm longer than 45 mm. The molecular sequences of Cytochrome C Oxidase Subunit 1 (COI) and 16S rRNA genes confirmed the morphological identification and thus the occurrence of Sturnira tildae in the Amazon biome of Maranhão. This record represents an eastward extension of the known distribution of the species in the Amazonia, to Cândido Mendes, Maranhão, within an area dominated by dense rainforest and influenced by tides. |
