Two new species of clearwing moths in the genus Diapyra Turner 1917 (Lepidoptera: Sesiidae: Paraglosseciini) from Taiwan and southeastern China

Diapyra Turner 1917 was previously recognized as a monotypical genus of the clearwing moth restricted to the Australian region. Two species with diagnostic features conformed to the genus were found from the Oriental region and described herein: Diapyra changchini sp. nov. from Taiwan and D. meihuashana sp. nov. from southeastern China. Diagnostic characters for the two species are provided using body colouration, wing pattern, and genitalia.

The larvae of Diapyra meihuashana were found to feed on callus tissue of Actinidia lanceolata (Actinidiaceae), whereas the hostplant and immature biology of D. changchini remains unknown. DNA barcode of 630 bp of COI fragment for both new species are also provided for utility on future phylogenetic studies of the clearwing moths.
