Distribution:

(based on species list records)   Genus is native to: Afrotropical bioregion.

Afrotropical Region: Africa, Eastern Cape, KwaZulu-Natal, Lesotho, Limpopo, South Africa, Southern Africa, Swaziland

Biology:

 

Both species of Streblognathus lack morphological queens. They belong to the minority of Ponerinae in which all workers are able to mate and store sperm. Young nestmate workers interact aggressively to establish a dominance hierarchy that regulates which individual becomes the single gamergate (=mated egglaying worker).
