Studies on an Enigmatic Blepharidatta Wheeler Population (Hymenoptera: Formicidae) from the Brazilian Caatinga

Blepharidatta is a rare Neotropical ant genus formed by predatory species whose small colonies nest in soil or leaf-litter. A population of Blepharidatta that presents affinities with the Cerrado species, Blepharidatta conops Kempf, was...
