Abstract
A new genus, Illiciomyia Tokuda, is erected for Illiciomyia yukawai sp. n. that induces leaf galls on illicium anisatum (Illiciaceae) in Japan. The new genus belongs to the subtribe Asphondyliina (Diptera: Cecidomyiidae :Asphondyliini) and can be distinguished from other genera by the lack of an apical spur on the first tarsomere on all legs and the shallow construction of male flagellomeres. In the subtribe Asphondyliina, the genus is considered to have a close relation to the genera Bruggmanniella and Pseudasphondylia by having common characters such as two separate teeth of gonostylus and transverse rows of rather long spines on the anterior half of dorsal surface of pupal abdominal segment. However, the paramere-like structure of Illiciomyia is selerotized, while paramere of Bruggmanniella and Pseudasphondylia is not sclerotized. These differences indicate that Illiciomyia is phylogenetically apart from Bruggmanniella and Pseudasphondylia.
