Anerastia nigropunctata Legrand (Lepidoptera: Pyralidae: Anerastiinae [auctorum]) is transferred to Ematheudes Zeller in the Peoriinae and redescribed. It is the only peoriine moth known from Aldabra Atoll, its type locality. Previously listed as endemic to the Aldabra Group of atolls, its range is extended to include Madagascar. Photographs of wing pattern (color figure), male and female genitalia, and male antenna [SEM] are included. This paper is the first of a planned series on the Aldabra Pyralidae (sensu stricto; see Minet, 1981).
