Taxonomy & Nomenclature
Synonym/s: Typhlops haitiensis Richmond, 1964; Typhlops sulcata Cope, 1868 (orthological error)
Last record: 1905?
IUCN RedList status: Extinct (as a subpopulation)
Known only from the holotype at present, but if the species has a much wider distribution then it is still extant. However, if the Navassa Island population deserves subspecific distinction then it is probably extinct as intensive efforts to catch this species have failed.
