On Phyletic Closeness Between South American and New Caledonian Spilopyrines (Chrysomelidae, Eumolpinae, Tribe Spilopyrini)

摘要

Among members of the eumolpine tribe Spilopyrini (Reid 1995), the South American genera Hornius and Stenomela and the New Caledonian Bohumiljania are especially similar, while the Australian and the New Guinean forms seem to stand a little apart. In this communication, by tracing taxonomic history of spilopyrines, and by taking into account their food plants, palaeogeological history of the Southern Hemisphere, anatomical features of spilopyrines, and their developmental stages, a possible phyletic closeness between the South American and the New Caledonian genera has been inferred.
