description: Euphoria sepulcralis Species-Group
(Appendix 3: Plate 1k–r)
Species in the sepulcralis species-group are distinguished by having a shiny surface, black, brown, or metallic coloration, pronotum with a cretaceous lateral line, base of the pronotum in front of the scutellum strongly emarginated, mesometasternal process well developed, and elytra with reniform and/or vermiform, cretaceous markings (except Euphoria boliviensis Blanchard). The male genitalia are useful for the diagnosis of some of the species.
Composition. The five species included in this group are: E. boliviensis Blanchard, E. leucographa (Gory and Percheron), E. lurida (F.), E. sepulcralis (F.), and E. yucateca Bates.
Natural History. Some of the species can become a nuisance for cultivated crops, fruits, and flowers.
