description: Euphoria herbacea Species-Group
(Appendix 3: Plate 2a–i)
Species in the herbacea species-group have the body surface tomentous, apex and sides of the clypeus reflexed in both sexes (strongly in males, weakly to moderately in females), antennal club sexually dimorphic (as long as or longer than stem in males and shorter in females), protibiae not sexually dimorphic (basal tooth frequently subobsolete in males of Euphoria leprosa Burmeister) and mesotarsal length sexually dimorphic (as long as or longer than mesotibiae in males, shorter in females). Euphoria leprosa is unique in the group for having the dorsum covered abundantly by cretaceous markings, the basal tooth of the protibiae frequently subobsolete in males, and the simpler genitalia. The male genitalia are diagnostic in this group. This group includes species distributed from the United States to Ecuador.
Composition. Four species are included in this group: E. herbacea (Olivier), E. leprosa Burmeister, E. steinheili Janson, and E. subguttata (Burmeister).
KEY TO THE SPECIES OF THE HERBACEA SPECIES- GROUP
