Aegialomys
Aegialomys is a genus of oryzomyine rodents from the lowlands and mountains of western Peru and Ecuador, including the Galápagos Islands.The species in this genus have historically been placed in Oryzomys, but according to cladistic research, the genus is more closely related to a group containing, among others, Nectomys and Sigmodontomys, than to Oryzomys.The generic name Aegialomys means "coastal mouse" in Ancient Greek (αιγιαλός "coast" and μῦς "mouse") and references the mostly coastal occurrence of the genus.There is however a third, undescribed species occurring on the Ecuadorian coast and the status of the two possible junior synonyms of A. xanthaeolus, A. ica Osgood, 1944 and A. baroni J.A.unresolved, although they have been described as distinct species,[1] as has the subspecies A. galapagoensis bauri.
