Japanese Journal of Systematic Entomology, 23 (1): 103–112. June 15, 2017. A Revision of the Genus Lycoperdina (Coleoptera: Endomychidae) from Japan Koichi SOGOH and Hiroyuki YOSHITOMI Entomological Laboratory, Faculty of Agriculture, Ehime University, Tarumi 3-5-7, Matsuyama, 790-8566 Japan Abstract The Japanese species of the genus Lycoperdina is revised. Three previously known species are redescribed: Lycoperdina castaneipennis Gorham, 1874, Lycoperdina dux Gorham, 1873 and Lycoperdina mandarinea Gerstaecker, 1858, and one new spe- cies is described: Lycoperdina hiranoi sp. nov. from Honshu and Hokkaido. The distributional pattern of Japanese species is briefly discussed. Introduction Systematics The genus Lycoperdina Latreille, 1807 belongs to the Genus Lycoperdina Latreille, 1807 subfamily Lycoperdininae Redtenbacher, 1844 (Tomaszewska, 2005), and contains 28 species: 18 from the Palearctic, 9 from Lycoperdina Latreille, 1807: 73 (Type species: Galleruca the Ethiopian, and 1 from the Nearctic Regions (Shockley et bovistae Fabricius, 1792); Tomaszewska, 2005: 47. Golgia Mulsant, 1846: 20 (Type species: Silpha succincta al., 2009). Linnaeus, 1767). From Japan, three species have been recorded. First report Lycoperdinodes Arrow, 1923: 485 [replacement name for of the genus from Japan was Gorham (1873), he described Lycoperdinella Arrow, 1920]. Lycoperdina dux from Hyogo, and recorded L. mandarinea Lycoperdinella Arrow, 1920: 23 [homonym Lycoperdinella from Nagasaki. Subsequently Gorham (1874) described L. Champion, 1913] (Type species: Lycoperdinella morosa castaneipennis from Hyogo. In addition Gorham (1887) and Arrow, 1920). Hirano (2011) recognized the presence of an undescribed Falsoylaia Pic, 1945: 10 (Type species: Falsoylaia species from Hokkaido and Honshu. obscuresuturalis Pic, 1945). In this paper, we review the Japanese species of the genus Lycoperdina. Diagnosis (modified Tomaszewska, 2005).
