Résumé :

Chaetarthria simillima sp.n. (Coleoptera: Hydrophilidae) is described. It is very closely related to C. seminulum (HERBST) with which it has been confused until now. The new species is widely distributed in western Europe. The aedeagi of both species are figured. Lectotypes are designated for C. seminulum and C. seminulum ssp. sithonica HEBAUER. Chaetarthria seminulum ssp. sithonica HEBAUER, 1993 is synonymized with Chaetarthria seminulum seminulum.
