Abstract

Two new species of the R. auricomus complex in Germany are described and depicted: R. rei­chertii and R. mosellanus. According to the present knowledge, their distribution area is confined to the country of Rhineland-Palatinate, R. reichertii occurs in the highland of Saar and Nahe river, R. mosellanus mainly in the Moselle valley. Both species are morphologically conspicuous: R. reichertii by size and wide-angled basal sinus, R. mosellanus by deep division and overlapping of the lateral leaf segments.
