A new genus and new species of Baetidae (Ephemeroptera) from lakes and reservoirs in eastern North America

Abstract

Waynokiops dentatogriphus, new genus and new species (Ephemeroptera: Baetidae), is described from nymphs collected from seven lakes and reservoirs in the eastern United States of America, specifically from the states of Virginia, Kentucky, Ohio, Indiana and Arkansas (type locale), during sampling for the USEPA National Lakes Assessment. The lateral abdominal expansions and the dorsal abdominal armature of the new genus are unique among Cloeon complex genera. Abdominal tergal projections are unusual for a small minnow mayfly from lentic habitats. Copyright © 2010 Magnolia Press.
