Eumetriochroa hiranoi is a moth of the family Gracillariidae. It is known from Japan (Honshū and the Ryukyu islands)[1] and China (Jiangxi).[2]
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.
The larvae feed on Styrax japonicus. They mine the leaves of their host plant.
Eumetriochroa hiranoi was named in honor of Nagao Hirano.
