Abstract
The chrysomelid genus Macrolema Baly 1861 is revised. 13 species are described including five new: Macrolema aenescens (Bowditch 1913), M. albascutica sp. nov., M. atripennis (Bowditch 1913), M. dickdaviesi sp. nov., M. giya sp. nov., M. karimui sp. nov., M. longicornis Jacoby 1895, M. metallica (Lea 1922), M. pulchra sp. nov., M. quadrivittata (Jacoby 1898), M. submetallica (Jacoby 1894), M. ventralis Lea 1921b, M. vittata Baly 1861. Macrolema vittata is a senior synonym of M. marginata Jacoby 1898 (syn. nov.). Allsortsia gen. nov., is erected for a species formerly in Macrolema, Allsortsia maculata (Lea 1922), comb. nov. Lectotypes are designated for Macrolema longicornis, M. vittata and Macrogonus quadrivittatus. Keys are provided for identification of the genera of Spilopyrinae and for the species of Macrolema. Macrolema is confined to the eastern rainforests of Australia (11 species) and highland New Guinea (2 species). Little is known of the biology of the species of Macrolema and Allsortsia, all of which are relatively rarely collected. A first-instar larva is tentatively ascribed to Macrolema.References
