Abstract

A new species of Isotogastrura from marine littoral sand of Fernando de Noronha Islands, Pernambuco State, Brazil is described and illustrated. It is characterized by the absence of prelabral setae, presence of a spatulate mucro, fusion of the dorsal part of Abd. IV and V and one pair of long circumgenital setae on males. It is similar to I. veracruzana from México. A key for the 9 species known in the genus is provided.
