(Appendix 3: Plate 4p–y)
Species in the pulchella species-group have a clypeus with the apex and lateral margins not raised, pronotal sides generally strongly angulate, protibiae not sexually dimorphic, and elytral striae composed mostly of deep grooves.
Composition. Four species are included in this group: Euphoria basalis (Gory and Percheron), E. canaliculata Orozco, new species, E. diminuta Orozco, new species, and E. pulchella (Gory and Percheron).
Natural History. Euphoria pulchella is the only species in the group that has been found associated with ants.
