Nomenclature
The following information is derived from Barry Bolton's Online Catalogue of the Ants of the World.
- didita. Atta didita Walker, 1859: 375 (s.w.) SRI LANKA.
- Type-material: 2 syntype workers.
- [Note: the two specimens that Walker describes as major and minor workers belong in different genera. The ‘minor worker’ is a Pheidole species (a specimen of P. sharpi according to Donisthorpe, 1932b: 576); the ‘major worker’ belongs in Dilobocondyla. This taxonomic conundrum may be best resolved by regarding the ‘major worker’ as the lectotype, and excluding the ‘minor worker’ from further consideration.]

Taxonomic Notes
The two specimens that Walker describes as major and minor workers belong in different genera. The ‘minor worker’ is a Pheidole species (a specimen of Pheidole sharpi according to Donisthorpe, 1932b: 576); the ‘major worker’ belongs in Dilobocondyla. This taxonomic conundrum may be best resolved by regarding the ‘major worker’ as the lectotype, and excluding the ‘minor worker’ from further consideration.
