Abstract
The Holarctic genus Rocetelion Matile is revised and three species are recognized; R. fenestrale (Fisher), R. fasciola (Coquillett), and R. humerale (Zetterstedt). Rocetelion fasciatum (Garrett) is proposed as a new junior synonym of R. fasciola. A new key, photographs of all species, and characters of the male and female terminalia are provided. The presence/absence of an antennal apicule was found to vary intraspecifically, thus making this character unreliable for distinguishing species in this genus.
