The monogeneric subtribe Mystropomina Chaudoir (Carabidae: Paussinae: Ozaenini) contains two species endemic to Australia: Mystropomus subcostatus Chaudoir and Mystropomus regularis BAnninger. In this paper, we describe and illustrate the larva of M. subcostatus providing the first larval description in this subtribe, thereby filling an important gap in our knowledge of paussine larval morphology. We compare the structural features of this larva with the other known larvae in the subfamily and provide an identification key to larvae of Australian paussine genera. We find no external structural features that indicate that this larva lives with ants, as do many other members of the carabid beetle subfamily Paussinae.
