Dudgeoneidae
Show Details
Common (1970) included members of this family in subfamily Cossinae of the Cossidae, but the family is treated as separate in Fletcher & Nye (1982) and by Minet (1983) who redefined the family.
It is monobasic, the genus Dudgeonea Hampson being known from Africa, Madagascar, India, New Guinea and Australia. It has general cossoid venation but differs from most members of the superfamily in having tympanal organs (Fig. 47) at the base of the abdomen. ‘Prototympanal’ organs, not necessarily homologous, are seen in the genera Chilecomadia Dyar (Chile), Rhizocossus Clench (Chile) and Pseudocossus Kenrick (Madagascar) which are placed in a subfamily of the Cossidae, Pseudocossinae, by Heppner (l984b).
