Taxonomy question

This topic is about the Mayfly Family Leptohyphidae

Read about the Tricorythodes genus for details. It is very important to trout anglers and it's the only significant trout stream genus in this family.

Most of the other genera are found only in warm waters in Mexico and the Southwest.

Posts: 4	I have two keys (Pekarsky et al and Merrit and Cummins) listing Tricorythodes in the tricorythidae family, but Troutnut and Voshell show tricorythodes in the leptohyphidae family. Has tricorythodes been moved to leptohyphidae or vice versa?

Has tricorythodes been moved to leptohyphidae or vice versa? I believe acceptance of family Leptohyphidae dates to 2000, as described in Generic Revision of the North and Central American Leptohyphidae (Ephemeroptera: Pannota) by Wiersema and McCafferty. The publication date of Aquatic Insects Of North America (Third Edition) by Merritt and Cummins is 1997. And, Freshwater macroinvertebrates of Northeastern North America by Pekarsky et al was published in 1990. So, both publications would have still listed genus Tricorythodes under family Tricorythidae.

Posts: 4	Thanks so much for the speedy responses. And a special thanks for the link to the Wiersema & McCafferty paper. I thought it might be a taxonomy change since the publication of the keys, but I figured I'd check with some experts!
