Euphoria fulgida Species-Group

(Appendix 3: Plate 1s–y )

Species in this group are distinguished by having a shiny surface, greenish to violaceous coloration, impunctate scutellum, males with antennal club longer than stem, sides of abdomen weakly to strongly ridged, mesotarsal length sexually dimorphic (as long as or longer than mesotibiae in males, shorter in females), abdomen of males at middle with weak to deep, medial, longitudinal depression, and distinctive male genitalia. All species in this group are of northern distribution, being present in the United States and northern and central Mexico.

Composition. There are three species included in this group: E. fulgida (F.), E. limbalis Fall , and E. monticola Bates.
