Xestogaster contains four described species:[3]

  1. Xestogaster mucorea (Kirsch, 1889)[4]Peru
  2. Xestogaster porosa (Marshall, 1922)[2]Colombia

Members of the genus Xestogaster are similar to members of the genera Exorides and Compsus.

According to Marshall:

The members of this genus can be distinguished from all their allies by the mesosternal tubercle and the highly polished venter.
