TYPE SPECIES: Trigona recursa Smith, 1863 .

DIAGNOSIS: This group includes the smallest species of Trigona and is generally similar to the hemipterophilic species of Ktinotrofia (vide infra). The subgenus can generally be characterized by the following combination of traits: integument entirely dark brown to black ( Fig. 144 View Figures 144–146 ); forewing membrane hyaline clear to faintly infumate or parchment-colored; mandible quinquedentate; labrum simple, surface gently and evenly convex; clypeus in profile with numerous erect bristles; scape with prominent, thick, black bristles, such bristles typically as long as scape diameter (sometimes even slightly longer) ( Fig. 149 View Figures 149–150 ); vertex with distinct postocellar ridge ( Figs. 145, 146 View Figures 144–146 ); distance from median ocellus to postocellar ridge equal to ocellar diameter ( Fig. 146 View Figures 144–146 ); metatibia with distinct corbicula, with retromarginal fringe setae abundant.

ETYMOLOGY: The new subgeneric name is a combination of the Greek nóstos (νόστος, meaning, “returning”) and Trigona . The gender of the name is feminine.

INCLUDED SPECIES: In addition to the type species, the subgenus includes T. permodica Almeida .
