Diagnosis. The forewing length is 18.0–19.0 mm in males and 20.0– 20.5 mm in females. Medioptyx kishidai sp. n. is externally very similar to C. fraterna sp. n. and differs from it only in the reduced greyish-brown suffusion on the hindwing. The genitalia structures of the new species are reminiscent of those of the genus Caliginoptyx gen. n. and the key differences between the two genera are listed below in the diagnosis of the latter. The comparison with members of the externally similar genera Collitoptyx and Thysanoptyx is provided above in the diagnosis of Medioptyx gen. n.

Distribution. The new species is known from East China (provinces of Fujian and Jiangxi).

Etymology. The new species is named after Mr Yasunori Kishida (Tokyo, Japan), renowned Japanese lepidopterist. The name is a noun in genitive case.
