Obolopteryx Cohn, Swanson & Fontana, 2014
Explanation of Names
Most of our U.S. species formerly placed in the genus Dichopetala were transferred to a new genus, Obolopteryx, by Cohn, Swanson, & Fontana 2014 (with the exception of D. pollicifera, which was placed in genus Planipollex). The genus Dichopetala now contains only one species D. mexicana, which is not found in the U.S.
