PHYLOGENY OF THE OLETHREUTINAE The failure of the analysis to recover several well accepted groupings based on unique apomorphies casts some doubt on the adequacy of the matrix. It was scored for all characters encountered within each genus as a very effective basis for descriptions and keys and to facilitate future work on the Papuan and Oriental fauna. However, it possibly contained too much polymorphism for a phylogenetic analysis, and time constraints did not allow rescoring a more suitable matrix based on exemplar taxa.

Olethreutine males are characterised by various secondary sexual modifications of the pregenital abdomen and its scale cover. These structures are often part of a functional unit involving the legs or scale pencils from the thorax or hindwing, and if they are present they may be taxonomically informative. Modified scaling on S2 is found in shallow folds laterally in Sycacantha Diakonoff and Lobesia (Fig. 222), and medially either as simple patches (Metaselena, Fig. 580) or complex tufts. Eversible deep pockets containing modified scales occur usually laterally on the abdomen between two segments (some Lobesia, Proschistis Meyrick, Pammenopsis Kuznetsov (Fig.

If the ratio of Olethreutini genera in Taiwan and China can be used as an approximation, the fauna of the Oriental Olethreutinae will number well in excess of 200 genera. The more detailed analysis given below of the olethreutine fauna within Australia shows that the strong north/south diminution in the number of Oriental genera continues within the Australian continent. Indeed, it carries on to New Zealand with only eleven olethreutine genera (Dugdale 1988). The number of genera of the Olethreutinae within Australia was scored by States, dividing Queensland into north of Townsville and south of Townsville; New South Wales into north of Sydney and south of Sydney, and Western Australia into the Kimberley and the remaining southern part of the state.
