Memoirs oj the Museum oj Victoria 56:1-63. The Australo-Papuan tribe Archimantini is redefined. The genera Psmthmantis Saussure and Rhocloinani is G'\gl\o-Tos are excluded. The genus. l;/.v//-<>/wam/.s Sjostcdt is recognised as valid and included. One new genus. C'ortlivlomantis. and four new species. Anhimantis gracilis.

Aiisiromantis gracilis Sjostedt a new synonym of A.alhomarginata Sjostedt and Coenomantis melanoptera (Tin- dale) a new synonym of C '.kraussiana (Saussure). Archiinaniis inermis Werner is transferred to the neotropical $snu$Aflgiia Serville. The subspecies Anhimantis laiistyla gigantca Beier is rejected as invalid. Keys to genera and species are provided. Information on biology is recorded, distributions given and relationships discussed.
