The tribe Acanthaclisini Navas contains 14 described genera which we recognize as valid. We have reared larvae of 8 of these (Acanthaclisis Rambur, Centroclisis Navas, Fadrina Navas, Paranthaclisis Banks, Phanoclisis Banks, Synclisis Navas, Syngenes Kolbe, and Vella Navas). In addition, we have studied preserved larvae from Australia which probably represent the genus Heoclisis Navas. This represents the majority of the taxa, lacking only the small genera Avia Navas, Cosina Navas, Madrasta Navas, Mestressa Navas, and Stiphroneuria Gerstaecker. Studies of these larvae have revealed structural differences, especially of the mandible, which we have employed to provide identification of these genera by means of descriptions, keys, and illustrations. Also, since no modern key exists, we are providing a key to the genera based on adults which will provide some further insight on the generic relationships. Observations on the tribal differences of Myrmeleontidae based on larvae are made with a preliminary key to the known tribes.
