Abstract

Based on male specimens a new species of the genus NavicorduliaMachado & Costa, 1995 is described from South French Guiana. This is the second species of the genus recorded for this country. The male of Navicordulia pascali n. sp. can be easily separated from all known males of the other species of the genus by the presence of a remarkable large ventral tooth at the base of the cerci. Navicordulia pascali n. sp. is a forest dwelling species inhabiting hilly landscape at low altitude. Adults seem to be on flight during the rainy season. The new species is most closely related to N. errans (Calvert, 1909) and N. leptostylaMachado & Costa, 1995, both from Cerrado of central Brazil. Affinities with the Venezuelan lowland N. vagans (De Marmels, 1989) are also probable. A differential diagnosis is given, and a key for Navicordulia species based on male characters is provided. The distributions are also given for all species of the genus. Aspects of ecology and biogeography are discussed.
