Abstract: | Three new species of the genus Macrorrhyncha, M. circularis, M. trilobata and M uncinata, are described from Japan. M. ezoensis (Okada, 1938) is redescribed and illustrations of male and female terminalia are provided for the first time. M uncinata is inferred to be related to M rostrata (Zetterstedt, 185 ). A key to the Japanese species is given.
