| This genus is easily recognized by its sharply notched clypeal margin and the unique dorsellum. |
|
| It can be identified by its brown to black color, well-developed petiolar process, and no median clypeal tooth. |
|
| Above the clypeal arch are two lateral clusters of strong basiconic sensillae, but no definite antennary rudiments are to be seen. |
|
| Head lengths were taken dorsally parallel to the coronal suture from the posterior margin to the anterior margin of the frontoclypeus, excluding clypeal lamellae. |
