At a Glance • Xenobiotic  

Identification

The eyes have several erect hairs and the clypeus of the worker is weakly depressed in the middle near the anterior border of the clypeus, and is without a medial carina, although several poorly developed lateral carinae are present. The propodeal spines are well developed, and thickened throughout. The anterior face of the petiole meets the dorsum in an angle, the posterior face is convex and rounded. The dorsum of the postpetiole is completely covered with punctures. The mesosoma has dense punctures. (Mackay and Mackay 2002)
