Abstract

The Nemonychidae of the Palaearctic region are revised. The introductory part deals briefly with fossil evidence, diversity of extant fauna, host plant associations and distribution patterns. Genera and species are redescribed, male and female genitalia and other morphological characters illustrated. The Palaearctic fauna consists of seven species in three genera, Nemonyx with four species, Cimberis with one, and Doydirhynchus with two. Nemonyx grisescens Reitter is synonymised with N. lepturoides (Fabricius), N. semirufus Pic raised from variety of N. lepturoides (Fabricius) to species status, N. variicolor Abeille synonymised with N. semirufus Pic, Doydirhynchus karamani Stierlin synonymised with D. austriacus (Olivier) and D. bicolor Pic raised from variety of D. austriacus (Olivier) to species status. Lectotypes of the following species are designated : Rhinomacer lepturoides Fabricius, Nemonyx grisescens Reitter, N. scutellatus Abeille, N. semirufus Pic, N. variicolor Abeille, Rh. attelaboides Fabricius, Curculio rhinomacer Paykull, Doydirhynchus castaneus Germar, D. karamani Stierlin, D. pallidicolor Pic, D. bicolor Pic, and D. _testaceus Pic. A specimen from Dresden is proposed as neotype for Rhynchites austriacus Olivier and deposited at the Muséum national d'Histoire naturelle, Paris.
