Euphoria biguttata Species-Group

(Appendix 3: Plate 1a–e View Plate 1 )

Species in the biguttata species-group are distinguished by having the clypeal apex and sides not raised, clypeal sides moderately to strongly convergent anteriorly, antennal club subequal in length in both sexes, scutellum impunctate, abdomen subequal in shape in both sexes, and form of the parameres.

Composition. Three species are included in this group: E. biguttata (Gory and Percheron) , E. canescens (Gory and Percheron) , and E. dimidiata (Gory and Percheron) .

Natural History. All species in the group are known to use Atta sp. ( Hymenoptera : Formicidae ) debris piles in the larval stage.
