New synonyms in the highly diverse caddisfly genus Smicridea (Trichoptera, Hydropsychidae)

Abstract

In this paper, Smicridea (Rhyacophylax) repula Oláh & Johanson, 2012 is synonymized with Smicridea (R.) lobata (Ulmer, 1909), and the species Leptonema islamarga Botosaneanu, 2002 is transferred to Smicridea (R.) as a synonym of S. lobata. Additionally, we present more detailed illustrations of the male genitalia of S. (R.) lobata and S. (R.) signata (Banks, 1903), and include notes on their distributions to aid in the identification of these two, often-confused species.
