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.
