Key to workers of Wadeura

- Mandible triangular (Fig. 13B–D); ventral margin of petiole less symmetrical ( Fig. 14B–D ); rare species from South America....... 2

2 Ventral margin of petiole a triangular lobe with pronounced anterior tooth ( Fig. 14 B )................................................. pauli

- Ventral margin of petiole a shallow lobe lacking anterior tooth ( Fig. 14C and D )................................................................... 3
