Description

Distinctive Characteristics of the genus (Dorow and Kohout 1995):

The subgenus Hemioptica can be defined within the genus Polyrhachis by the possession of following characters:

1. Eyes posteriorly truncate in Polyrhachis boltoni and Polyrhachis scissa.

2. Sides of head with sharply defined longitudinal carinae separating the genae from the ventral parts of the head.

3. Anterior clypeal margin arcuate, entire.

4. Pronotum convex, shield-shaped, extending posteriorly and concealing the median portion of mesonotal dorsum.

5. Mesosoma lacking any traces of armament.

6. The metanotal groove deeply impressed and elaborate.
