Revision of Mandarella Duvivier from Taiwan, with a new species, new synonymies and identities of highly variable species (Insecta, Chrysomelidae, Galerucinae, Alticini).
Taiwanese species of Mandarella Duvivier are compared on the basis of morphological and molecular evidence. Only three of eleven morphospecies are considered to be valid. Mandarella uenoi (Kimoto, 1969) is transferred from the genus Luperus Geoffroy. Stenoluperus taiwanus Kimoto, 1991 and Stenoluperus kimotoi Döberl, 2001 are synonymized with Mandarella uenoi. Taiwanese records of Stenoluperus tibialis Chen, 1942, Stenoluperus nipponensis Laboissière, 1913, and Stenoluperus potanini (Weise, 1889) were based on misidentifications and represent Mandarella uenoi. The Taiwanese population previously erroneously identified as Stenoluperus pallipes Gressitt and Kimoto, 1963 is here described as a new species, Mandarella tsoui sp. n., Stenoluperus esakii Kimoto, 1969, Stenoluperus matsumurai Takizawa, 1978, and Mandarella taiwanensis Medvedev, 2012 are synonymized with Mandarella flaviventris (Chen, 1942).
