Eumetriochroa hiranoi is a moth of the Gracillariidae family. It is known from Japan (Honshū and the Ryukyu islands) and China (Jiangxi). The wingspan is 4.6-6.1 mm. This species appears very similar to Eumetriochroa kalopanacis but can be distinguished by from the latter by differences in the genital structures. Eumetriochroa hiranoi was named in honour of Nagao Hirano.
