A new leaf-mining moth, Caloptilia aesculi, sp. nov. (Lepidoptera: Gracillariidae: Gracillariinae) feeding on Aesculus chinensis Bunge (Hippocastanaceae) from China

Abstract

A new species of the genus Caloptilia associating with the Chinese horse chestnut, Aesculus chinensis Bunge (Hippocastanaceae) from China is described. The photographs of the adults, male and female genitalia, larva and pupa, the leaf mines and leaf shelters (rolls and stacks) are given. This is the first report of host association with Hippocastanaceae in the subfamily Gracillariinae. The sequence of mitochondrial COI barcoding region of this species is provided and its phylogenetic position is analyzed with other Caloptilia species.
