Qwaqwaia has a dorsally wide pronotum, a character shared with members of the Synergini and the Aylacini (especially some species of Phanacis). However, the presence of only two prominent teeth on the right mandible and a parascutal carina that extends anteriorly all the way to the notaulus separate Qwaqwaia scolopiae from species of these two tribes (Liljeblad et al. 2011).

Qwaqwaia has a strong, sharp occipital carina, which distinguishes this genus from both other Afrotropical representatives of this family where the carina is absent. Marginal cell of forewing closed, with veins heavily pigmented, a character state shared with Rhoophilus, however, the areolet is elongate rhomboidal whereas it is triangular in Rhoophilus. The hypopygium is short, abrupt, without a projecting ventral spine (present in both other genera), with dense setae forming an apical tuft.
