Sumario:The genus Atrachya Chevrolat is redefined based on study of the type species A. menetriesii (Faldermann, 1835). All Taiwanese species of Atrachya are transferred to three new genera: A. hirashimai Kimoto, 1976 and A. nitidissima (Chûjô, 1935) are transferred to Neochyagen. nov.; A. mediofasciata Kimoto, 1976 is transferred to Tsouchyagen. nov.; A. unifasciata Takizawa, 1978 is transferred to Chinochyagen. nov. Two species are described: N. chengisp. nov. and N. tsouisp. nov.Atrachya bicoloripennis (Chûjô, 1938) and A. saramao (Chûjô, 1962) are regarded as synonyms of N. nitidissima (Chûjô, 1935) comb. nov., and Monolepta tsoui Lee, 2009 is synonymized with T. mediofasciata (Kimoto, 1976) comb. nov.Monolepta sublata Gressitt & Kimoto, 1963 is redescribed and transferred to Chinochyagen. nov. Taiwanese records of Monolepta sublata are based on misidentifications and represent specimens of C. unifasciata. Variablity of adult color patterns is discussed.
