Below are various keys to groups with Perdita and Macrotera that are either newly created by me, or annotated versions of Timberlake keys (most of the annotations have been done by Dr. Terry Griswold, Research Entomologist at the USDA-ARS). The newly created keys should be considered working drafts, so they may contain errors. If you have any questions about them, feel free to contact me.
