Abstract

Adult males were reared from larvae of the type previously associated with Anepeorus. These adult males key to and fit the description of Heptagenia cruentata Walsh. Because the larvae are very different from those of other Heptagenia species, a new genus, Raptoheptagenia, is proposed for cruentata. Adult males of Raptoheptagenia differ from those of Heptagenia in the anastomosis of two or more crossveins in the stigmatic area of the forewing, and in the subequal lengths of the foretarsus and tibia.

Résumé

Les auteurs ont élevé des adultes mâles à partir de larves du genre précédemment associé avec Anepeorus. Ces mâles suivent les critères et descriptions pour Heptagenia cruentata Walsh. A cause que les larves sont très différentes de celles d’autres espèces de Heptagenia, nous proposons un genre nouveau, Raptoheptagenia, pour cruentata. Les adultes mâles de Raptoheptagenia diffèrent de ceux de Heptagenia par l’anastomose de deux ou plus veines croisées dans la région stigmatique des ailes antérieurs, et par les longueurs quasi-égales des tarses et tibias antérieurs.
