The Nerthra alaticollis species-group is defined as a monophyletic group on the basis of wing and genitalic characters. Two new species are described: Nerthra appha n. sp. and N. polhemi n.sp. Nerthra membranacea Nieser is recognized as a junior synonym of N. adspersa. Nerthra tuberculata (Montandon) and N. praecipua Todd are removed from the alaticollis species-group. Nine species are assigned to the species-group, and all species are described with illustrations. A phylogeny of species is provided.
