Taxonomic Notes
Lenhart et al. (2013), discussing Dinoponera australis bucki - The male coloration difference is the basis for the designation of the subspecies D. australis bucki and D. a. nigricolor. These may be separate species or the product of intra-specific variation, but this cannot be diagnosed here as the types designated by Borgmeier (1937) were not available to us and the extent of intra-specific variation could not be determined from the limited sample size available.

Lenhart et al. (2013), discussing Dinoponera australis nigricolor - The male coloration difference is the basis for the designation of the subspecies D. australis bucki and D. a. nigricolor. These may be separate species or the product of intra-specific variation, but this cannot be diagnosed here as the types designated by Borgmeier (1937) were not available to us and the extent of intra-specific variation could not be determined from the limited sample size available.

Lenhart et al. (2013), discussing Dinoponera snellingi - Male. Specimens of this species are distinct in several respects. The combination of a bicolored body and head possessing bulging compound eyes and ocelli is unique to this species. More definitive is the shape of the aedeagus which possesses a large ventral lobe and finger-like serrated flange. The short broad digitus volsellaris with finely toothed basal lobe is distinctive, as well as the paramere shape.
