Abstract

Cryptonanus agricolai (Moojen, 1943) is a small didelphid widely distributed across of central and northeastern Brazil and in the Brazilian Atlantic Forest. A recent phylogeographic study of this species identified three major mtDNA clades with strong geographic structure. Here, we present new records of C. agricolai in northeastern Brazil, including the first report for Maranhão state. We also identify a novel mtDNA lineage, sister to one of the three major clades, in some specimens from Maranhão, indicating that C. agricolai is morphologically and genetically more variable than previously recognized.
