A taxonomic revision of the Australian Chrysomelinae, with a key to the genera (Coleoptera: Chrysomelidae)

The Australian genera of Chrysomelinae are reviewed and redefined. A new genus of Chrysomelinae is described: Alfius gen. n., from Queensland, with three species, A. hieroglyphicus (Lea), A. pictus (Lea) and A. pictipennis (Lea), all transferred from Oomela Lea. The hitherto Papuan genus Sphaerotritoma Arrow, with two species, is removed from Erotylidae and placed in Chrysomelinae, and one Australian species added, S. coccinelloides (Lea), from Oomela. A key is provided for adults of the 42 native and 4 exotic genera of Chrysomelinae occurring in Australia. Information on host-plants and immature stages is listed where known. Taxonomic and nomenclatural problems in the Australian or Papuan Chrysomelinae are resolved, as follows: (i) new or confirmed generic synonyms, senior name first: Callidemum Blanchard (= Augomela Baly, = Clidonotus Chapuis syn. n., = Kurumela Gressitt, = Stethomela Baly); Chalcomela Baly (= Cyclomela Baly syn. n., = Micromela Baly), Dicranosterna Motschulsky (= Trochalodes Weise syn. n., = Paropsimelina Daccordi syn. n.), Oomela Lea (= Nannoda Weise), Paropsimorpha Lhoste (= Thaumalegastra Daccordi syn. n.), Paropsis Olivier (= Procrisina Aslam syn. n.), Paropsisterna Motschulsky (= Chrysophtharta Weise syn. n., = Sterromela Weise syn. n., = Xanthogramma Weise syn. n.), Platymela Baly (= Macelola Selman syn. n.), Trachymela Weise (= Chondromela Weise); (ii) reversal of synonymy (sensu Daccordi 1994) by removal of: Phola Weise from Chalcolampra Blanchard; Rhaebosterna Weise from Faex Weise; Platymela Baly from Callidemum Blanchard; (iii) replacement of species homonyms: Phyllocharis ewani nom. n. for Phyllocharis abdominalis (Jacoby, 1894) nec Baly, 1867; Tinosis leai nom. n. for T. fasciata (Lea, 1915) nec Weise, 1908b; (iv) new species synonymy, senior name first, in the original combination with present placement in square brackets if different: Aesernia [Promechus] australica Jacoby (= Aesernia bipunctata Weise syn. n., A. mjoebergi Weise syn. n.); Australica [Platymela] digglesi Baly (= Platymela mjoebergi Weise syn. n.); Australica [Paropsides] erudita Baly (= Paropsis complicata Blackburn syn. n.); Augomela [Paropsimorpha] elegans Baly (= Stethomela armiventris Lea syn. n.); Chalcolampra rufipes Jacoby (= Phyllocharis fulvifrons Jacoby syn. n.); Chrysomela [Gastrophysa] viridula Degeer (= Lamprolina unicolor Jacoby syn. n.); Eugastromela metasternalis Lea (= E. flavitarsis Lea syn. n.); Grammicomela quadrilineata Lea (= Stethomela rara Lea syn. n.); Micromela [Chalcomela] cupripennis Baly (= Stethomela purpureipennis Lea syn. n.); Notoclea [Chalcomela] splendens Macleay (= Chalcomela illudens Baly syn. n.); Oomela [Tinosis] bicolor Wilson (= Nannoda femoralis Weise syn. n.); Oomela trimaculata Lea (= Nannoda bimaculata Weise syn. n.); Oomela variabilis Lea (= Nannoda variabilis Weise syn. n.); Paropsis [Dicranosterna] circe Stål (= Paropsis pedestris Chapuis syn. n.); Paropsis [Peltoschema] delicatula Chapuis (= Peltoschema vestalis Daccordi & De Little syn. n.); Paropsis [Paropsisterna] semifumata Blackburn (= Xanthogramma pellucida Weise syn. n.); Chalcomela [Sphaerotritoma] nigripennis Baly (= Sphaerotritoma laeta Arrow syn. n.); (v) type species designations: Phyllocharis splendens Guérin-Méneville for Aesernia Stål, Chrysomela hypochalcea Germar for Augomela Baly, Chalcomela illudens Baly for Chalcomela Baly, Nannoda variabilis Weise for Nannoda Weise, Platymela sticticollis Baly for Platymela Baly, Promechus splendidus Boisduval for Promechus Boisduval, Stethomela submetallica Baly for Stethomela Baly;Phyllocharis wollumbina (Daccordi) comb. n.; Platymela bimaculiceps (Lea) comb. n., P. cephalotes (Lea) comb. n., P. digglesi (Baly) comb. n., P. flavescens (Blackburn) comb. n., P. flavida (Lea) comb. n., P. hasenpuschi (Daccordi) comb. n., P. maculiceps (Lea) comb. n., P. monochromatea (Lea) comb. n., P. quadripustulata (Baly) comb. n., P. transversa (Baly) comb. n.; Rhaebosterna interruptofasciata (Baly) comb. n.; Sphaerotritoma coccinelloides (Lea) comb. n., S. nigripennis (Baly) comb. n.; Tinosis bicolor (Wilson) comb. n.; Trachymela echo (Blackburn) comb. n.; (vii) lectotype designation for Oomela hieroglyphica Lea; (viii) recognition of two unavailable nomina nuda: subtribal name Calomelina Daccordi & De Little; generic name Gastromela Daccordi; (ix) listing of lapsus calami with their attempted identification.
