The genus Tartarisus Pascoe is endemic to the Maule and Valdivian districts of the Subantartic province of southern South America. This genus includes five species: Tartarisus concinnus (Philippi) (revalidated here from synonymy with T. signatipennis), T. griseus (Philippi), T. perforatipennis (Blanchard), T. signatipennis (Blanchard), and T. subfasciatus (Blanchard). A key, redescriptions, photographs, and illustrations of the species are provided. A cladistic analysis using 20 characters from external morphology and male and female genitalia produced one cladogram (CI = 0.76, RI = 0.72, length 28 steps). The cladogram shows the following phylogenetic sequence: (T. perforatipennis ((T. griseus T. subfasciatus) (T. signatipennis T. concinnus))).
