As revised here, the subgenus Gymnopternus Loew of the genus Hercostomus (Diptera: Dolichopodidae) comprises nine western European species. H. aerosus, H. metallicus and H. assimilis are re‐described, and H. silvestris and H. blankaartensis are described as new. Keys to males and females are given which include all western European species of this subgenus. A phenogram based on twenty‐seven morphological attributes is compared with cluster analyses based on the habitat preferences and seasonal activity patterns. The results are discussed in the light of the niche separation versus coexistence principles.
