Abstract
A new species of caeciliid caecilian, Microcaecilia iyob sp. nov., is described based on a single specimen from Guyana that was previously assigned to M. unicolor (Duméril, 1864), a species known with certainty only from French Guiana. The new species differs from other Microcaecilia in its pattern of annulation and/or major features of the dentition.
