 In addition, the V-shaped hypoflexids and narrow third molar of "M. audreyae" contrast with the narrow, parallel-sided hypoflexids and broad third molar of ""Ekbletomys"".These characters, and others observable in species of "Megalomys" represented by more complete material, convinced Ray that "M. audreyae" and ""Ekbletomys"" are not only distinct species, but indeed share no close relationship.Instead, he proposed that the combination of large size, occurrence in the Lesser Antilles, and similarity in molar morphology indicated a relationship between "M. audreyae" and other species of "Megalomys", and he suggested that the similarly sized "M. curazensis" from Curaçao, off Venezuela, may be most closely related to "M. audreyae".
