Locally common in the Afrotropical region, particularly in arid regions.

Ventral margin of malar space and clypeus with distinct protuberances. Lateral pronotal carina present. Notauli faint, often only present anteriorly and posteriorly on mesoscutum. Ventral border of mesopleural triangle distinct, not rounded (at least posteriorly). Base of syntergum of metasoma glabrous. Most easily confused with Tobiasiana Kovalev (not an Afrotropical taxon), but differing by the conical protuberance on the ventral clypeal margin (spatulate in Tobiasiana). Within the Afrotropical region, Nordlanderia most closely resembles Ealata by having reduced notauli and a smaller scutellar plate; can be distinguished from Ealata by the presence of numerous tubercles along the rim of the scutellar plate (single central tooth in Ealata), and typically more complete notauli.

Mainly Afrotropical, but extending to the Oriental region and the southern Palearctic.
