          Abstract

          The taxonomic status of Pyrrhalta Joannis, 1865 and allied genera Tricholochmaea Laboissière, 1932 and Xanthogaleruca Laboissière, 1934 is discussed based on the study of Taiwanese species. Tentatively, Xanthogaleruca and Pyrrhalta are regarded as valid genera while Tricholochmaea is a synonym of Pyrrhalta. Fourteen species are recognized and redescribed, including P. gressitti Kimoto, 1969; P. taiwana Kimoto, 1969; P. viridipennis Kimoto, 1981; P. igai Kimoto, 1981; P. meifena Kimoto, 1976; P. maculata Gressitt & Kimoto, 1963; P. tsoui Bezděk & Lee, 2019; P. semifulva (Jacoby, 1885); P. discalis Gressitt & Kimoto, 1963; P. ishiharai Kimoto, 1994; P. shirozui Kimoto, 1969; P. kobayashii Kimoto, 1974; P. ohbayashii Kimoto, 1984; and P. takizawai Kimoto, 1996. Taiwanese populations identified as Xanthogaleruca aenescens (Fairmaire) were misidentified and those are described as a new species, X. yuae sp. nov. Xanthogaleruca aenescens is redescribed for comparison. Eight additional new species of Pyrrhalta are described: P. alishanensis sp. nov., P. houjayi sp. nov., P. formosanensis sp. nov., P. jungchani sp. nov., P. lui sp. nov., P. meihuai sp. nov., P. tahsiangi sp. nov., and P. wulaiensis sp. nov. Type specimens of Galerucella lineatipes Takei, 1916 were rediscovered and are designated as lectotype and paralectotype. Galerucella lineatipes is removed from synonymy with G. calmariensis (Linnaeus, 1767) and regarded as a senior synonym of P. humeralis (Chen, 1942), syn. nov. Most Pyrrhalta species can be classified into four species groups based on their morphological and genitalic similarity. host plants and other biological information are provided for almost all species.

          How many genera and species of Galerucinae s. str. do we know? Updated statistics ( Coleoptera , Chrysomelidae )

          Abstract Galerucinae s. str. is a rich group of leaf beetles. A new, up-to date checklist of Galerucinae genera in the world is provided, including the number of valid species of each genus. Genera and species were counted in literature published before the end of 2016. In summary, 7145 species (7132 recent, 13 fossils) and 192 subspecies from 543 genera (542 recent, 1 fossil) were quantified in Galerucinae s. str. In comparison with the previous catalogue of worldwide Galerucinae (Wilcox 1971–1973), an additional 91 valid genera, 1341 valid species (1337 recent, 4 fossils) and 38 subspecies have been published; 43 genera were synonymized, four genera were transferred into Alticini , two subgenera were elevated to genus rank, and one genus was downgraded to subgenus rank. The updated list of references to taxonomic publications on Galerucinae s. str. from the period 1971–2016 is provided.
