Abstract

The genus Metablax is endemic to New Zealand. The fauna falls into 2 distinct species‐groups, here designated the acutipennis‐group (acutipennis, brouni) and the approximans‐group (approximans, gourlayi n.sp., cinctiger). All taxa are described and illustrated, and a key is given for their separation. A typical Metablax larva is described and illustrated. The systematic position of the genus is discussed in relation to the Neotropical Campsosterninae, and on the basis of both adult and larval characters Metablax is here assigned to subfamily Campsosterninae.
