Abstract

Descriptions of Procloeon rubropictum (McD.), P. quaesitum (McD.), and P. rufostrigatum (McD.) are expanded to include features not previously published. A description of the nymph of P. quaesitum is given for the first time. Procloeon irrubrum sp.nov. is described from nymphs and female imagoes. From our interpretation of preliminary data, it is possible that P. rufostrigatum and P. rubropictum form one species group; P. quaesitum is included with P. pennulatum (Eaton) in another. Procloeon irrubrum does not fit either species group but shows some affinities to the P. rufostrigatum group. Some characters for separating the nymphs of Procloeon and Centroptilum are given.

Résumé

Les descriptions de Procloeon rubropictum (McD.), de P. quaesitum (McD.) et de P. rufostrigatum (McD.) ont été complétées par addition de caractéristiques inédites. La description de la larve de P. quaesitum est présentée pour la première fois. Procloeon irrubrum sp.nov. est décrit ici après examen de larves et de femelles adultes. D’après l’analyse des données préliminaires, nous croyons que P. rufostrigatum et P. rubropictum constituent un groupe d’espèces et que P. quaesitum appartient à un autre groupe qui comprend aussi P. pennulatum (Eaton). Procloeon irrubrum ne correspond à aucun de ces deux groupes, mais comporte certaines affinités avec le groupe P. rufostrigatum. Les caractéristiques qui permettent de séparer les larves de Procloeon des larves de Centroptilum sont présentées.
