La recherche de topotypes de Rhithrogena nivata (Eaton, 1871) a permis de retrouver cette espèce pour la première fois depuis sa description. Des imagos [math] et [math] ont été obtenues par élevage de larves. Les genitalia des [math] sont identiques à ceux du seul exemplaire restant de la série type (lectotype, British Museum). Les imagos sont redécrites.
Abstract
A search for topotypes of Rhithrogena nivata (Eaton, 1871) yielded the first specimens seen since the original description. Male and female imagos were obtained by rearing larvae. The male genitalia are identical with those of the sole remaining specimen of the original type series, a lectotype in the British Museum. The imagos are redescribed.
