Cyclopes didactylus, Northeastern Brazil subpopulationData Deficient (DD)Photograph: Flávia MirandaCommon Names: Silky anteater (English), pygmy anteater(English), tamanduaí (Portuguese), tamanduacigarra(Portuguese).Assessment Rationale: There is no doubt that rapidand ongoing deforestation of the Atlantic forest isnegatively affecting the northeastern population ofC. didactylus, as the species cannot survive in the sugarcane plantations that are replacing the native vegetationin this area and the remaining patches of suitablehabitat are increasingly fragmented. It is thereforehighly probable that this population requires listingin a threatened category. The lack of basic dataon its ecology, population size and density, however,currently do not allow a realistic assessment of itsconservation status. The northeastern population ofC. didactylus is therefore classified as Data Deficient.Field studies are urgently needed to confirm the taxonomicstatus of this population and to obtain sufficientinformation for an appropriate assessment of itsconservation status.Taxonomic Note: The taxonomic status of this isolatedpopulation of C. didactylus needs to be confirmed.Geographic Range: This subpopulation of the silkyanteater occurs in coastal northeastern Brazil, inthe states of Paraíba, Pernambuco, Alagoas and RioGrande do Norte (Miranda and Superina, 2010; Fig.5). It is isolated from the main silky anteater populationby approximately 1,000 km. The extent of occurrenceof this subpopulation is approximately 25,000km 2 .Population: No data are available on the populationsize or density of this isolated population of C. didactylus.Ongoing deforestation is likely to further fragmentthe habitat and decimate the wild population ofthis smallest of all anteaters.Habitats and Ecology: The northeastern subpopulationof C. didactylus is restricted to tropical moistlowland forests. Nothing is known about its biologyor ecology.Threats: This population of silky anteaters is threatenedby rapid deforestation of its suitable habitat(Atlantic forest) due to the increase in sugar caneplantations, which, in addition to direct habitat loss,also leads to habitat fragmentation and degradation.Only five percent of the original extent of suitablehabitat remain intact (Galindo-Leal and De GusmãoCâmara, 2003). The current area of Atlantic forest inthe range states amounts to approximately 3,000 km 2(Campanili and Prochnow, 2006). Furthermore, silkyanteaters are captured for illegal trade (Miranda, pers.comm., 2010).Conservation: There are no State or National parkswithin the range of the northeastern Brazil subpopulationof C. didactylus. Projeto Tamanduá (Brazil) isperforming awareness programs in the area.Assessors: Miranda, F. and Superina, M.Evaluators: Bermúdez Larrazabal, L. and Meritt Jr.,D.A.Edentata no. 11(2) • 2010 101
