Gymnetron fuscescens Rosenschoeld, 1838

Rosenschoeld (1838) described Gymnetron fuscescens from specimens from Tauria ( Turkey) and reported that they were very similar to R. plagiella but smaller. After the examination of a syntype, Brisout de Barneville (1865) provisionally concluded that this taxon might be a distinct species very closely related to R. tetra . Desbrochers des Loges (1893) synonymized this taxon with R. tetra , an opinion followed by Reitter (1907) and Hoffmann (1958). At the NHRS we examined a male syntype labelled “♂ / Tauria, Steven / Typus ” (lectotype here designated), which we identified as R. tetra based on the shape of the rostrum, which is shorter than that of male R. verbasci , and the size, which is larger than in R. moroderi (see below).
