The genus Lochmaea Weise, 1883 in Taiwan: results of taxonomic expeditions by citizen scientists (Coleoptera, Chrysomelidae, Galerucinae)

Abstract. More than 520 specimens of the chrysomelid genus Lochmaea were available for study as the result of collecting efforts by citizen scientists. Taiwanese species of Lochmaea can be separated into two species groups based on presence or absence of hind wings. The Lochmaealesagei group (winged) contains L.lesagei Kimoto, 1996 and L.tsouisp. n. The L.smetanai group (wingless) contains L.smetanai Kimoto, 1996, L.chenisp. n., and L.jungchanisp. n. Members of the L.smetanai group inhabit alpine microhabitats and are the only wingless galerucines in Taiwan that occur in harsh environments, as is the case with most brachelytrous Chrysomelidae.
