| Surface glabrous with highly superficial microreticulation, much finer than pronotal microreticulation, consisting of dense transverse meshes. |
| The group is diagnosed by the truncate third labial segment, the similar wing venation, the absence of a pronotal collar, and the distinct hyperpleural lobes. |
| The genus is characterized by the strongly vertical head with the anterior third or so projected upwards and weakly to distinctly deflexed over anterior pronotal margin. |
| The anterior pronotal angles are produced forward, the metaventrite is very short and the hind wings are absent. |
