New Zealand's coxella, karo, knobbled, and speargrass weevils are revised. Sixteen species are recognised in the genus Lyperobius Pascoe, 1876, of which eight are new (australis, barbarae, clarkei, eylesi, glacialis, montanus, patricki, and townsendi). Four species are recognised in the genus Hadramphus Broun, 1911. Karocolens Kuschel, 1987, based on K. pittospori Kuschel, 1987, is reduced to synonymy with Hadramphus, and the new combination H. pittospori is proposed. Lyperobius aciphyllae Broun, 1917 is a subjective synonym of L. cupiendus Broun, 1886. Genera and species are described, and a key to adults is given. Life history, biology, and conservation status and value are reviewed. A numerical phylogenetic analysis exploring the relationships of the two genera and their included species is shown to contain significant phylogenetic structure, against a null hypothesis of random noise, by bootstrapping and tree-length distribution skewness. Biogeographical and ecological history, including host plant shifts, are discussed.
