First record of Dermanura gnoma for the threatened Pernambuco Endemism Center, northern Atlantic Forest, with phylogenetic insights

Abstract

Abstract Dermanura gnoma (Handley, 1987) is a phyllostomid bat that occurs in South America. In Brazil, most of the records are concentrated in the Amazon Forest, with sparse data from Cerrado and Atlantic Forest. This study presents the first record of D. gnoma for Alagoas state, and for the Pernambuco Endemism Center (PEC), the most threatened region of the Brazilian Atlantic Forest, characterized by its high rate of endemism, habitat loss, and fragmentation. The species was surveyed at Murici Ecological Station and its identification was supported by morphological and molecular data. We provide the first COI and CYTB gene sequences for this species in the entire Atlantic Forest. Phylogenetic analyses reveal that the generated sequences were recovered in the same clade as the published sequences of D. gnoma from the Amazonian Forest, corroborating the disjunct distribution pattern between Amazonia and PEC, as already reported for other vertebrate taxa. Also, this record increases the number of bat species to 71 for the PEC and extends the geographic distribution of D. gnoma by 758 kilometers to the northeast of its range.
