Etymology Gr grex  HNS  , herd or flock.

Diagnosis A medium-sized, slender, yellow species placed in the flavens  HNS  group (but with habitus intermediate to the punctithorax  HNS  group), whose major has completely foveolate dorsum of the head (exclusive of central clypeus and frontal triangle) and mesosoma; carinulae limited to the anterior two-thirds of the head capsule; profde of the posterior half of the head flat in side view; relatively long, slender, nearly erect propodeal spines; low but distinct mesonotal convexity; and low postpetiolar node in side view.

Minor: foveolation as in major; sparse, paired hairs on mesonotal dorsum; and short, erect propodeal spines that curve forward. Somewhat similar to humida  HNS  , but different in many details, as figured.
