Abstract

The species of Limnozetes of northeastern North America are treated. A new generic diagnosis is given. Eight new species are described: L. latilamellata, L. guyi, L. borealis, L. onondaga, L. amnicus, and L. palmerae on the basis of adults and immatures, and L. lustrum and L. atmetos on the basis of adults. Identification of adults and immatures of these species is presented in tabular format. The range of morphological variation exhibited by these species is discussed. Transformation series for eight character states in Limnozetes are hypothesized on the basis of comparison with Hydrozetes. A key is given to the adults of the nine species of Limnozetes recorded from northeastern North America.

Résumé

Les espèces de Limnozetes provenant de la partie Nord-est de l’Amérique du Nord sont étudiés. Une nouvelle diagnose est presentée pour le genre. Huit nouvelles espèces sont décrites : L. latilamellata, L. guyi, L. borealis, L. onondaga, L. amnicus, et L. palmerae par les adultes et les juvéniles, et L. lustrum et L. atmetos par les adultes. Les adultes et les juvéniles de ces espèces peuvent être identifiées à l’aide d’un tableau d’identification. L’entendue de la variation morphologique présente chez ses espèces est discutée. Une hypothèse sur les séries de transformation pour huit caractères de Limnozetes est proposée par comparaison avec Hydrozetes. L’ouvrage comprend une clé des neuf espèces de Limnozetes provenant de la partie Nord-est de l’Amérique du Nord.
