A hierarchical classification of the Timpanoginae (Ephemeroptera : Ephemerellidae) and description of a new species from Quebec
Classification hiérarchique des Timpanoginae (Ephemeroptera : Ephemerellidae) et description d'une espèce nouvelle du Québec
Department of Entomology, Purdue University, West Lafayette, IN 47907, USA
A strictly phylogenetic classification of the supergeneric taxa within the subfamily Timpanoginae includes the Attenellini, n. tribe, consisting of Attenella Edmunds ; the Eurylophellini, n. tribe, consisting of Dentatella Allen, n. stat., and Eurylophella Tiensuu ; and the Timpanogini, n. tribe, consisting of Timpanoga Needham and Dannella Edmunds, n. stat. Dentatella danutae McCafferty, n. sp., is described from larvae taken from a stream in southern Québec, Canada. The new species differs from the obviously closely related D. bartoni (Allen) by possibly striking coloration differences as well as numerous slight structural differences.
Résumé
Une classification strictement phylogénétique des taxons supergénériques à l'intérieur de la sous-famille des Timpanoginae inclut : les Attenellini, n. tribu, consistant en Attenella Edmunds ; les Eurylophellini, n. tribu, comprenant Dentatella Allen, n. stat., et Eurylophella Tiensuu ; et les Timpanogini, n. tribu, comprenant Timpanoga Needham et Dannella Edmunds, n. stat. Dentatella danutae McCafferty, n. sp. est décrite à partir de larves provenant d'un cours d'eau du Sud Québec, Canada. L'espèce, nouvelle diffère de la très voisine D. bartoni (Allen) par de possibles différences frappantes sur la coloration, ainsi que par de nombreuses légères différences de structure.
