Genus Platymorpha Jacoby, 1888

Platymorpha Jacoby, 1888: 602 (type species Platymorpha variegata Jacoby, 1888 , by original designation).

Remarks

This genus includes three described species. They occur in Mexico and Central America. See Figs 106 , 176 , and 177 for habitus illustrations and morphological details. The preapical notch of the male middle tibia, characteristic of the section Phyllecthrites , is very small or absent in some species of this genus. The following key enables correct identification, whether or not the notch is interpreted to be present. Chthoneis smaragdipennis Jacoby, 1888 , formerly included in Platymorpha , is herein transferred to Trachyelytron gen. nov.
