ABSTRACT	Three cecidomyiid galls were found on Machilus thunbergii Hayata (Lauraceae) in the Guandaushi forest of central Taiwan. The one on the twigs is the spindle-shaped gall. The two on the leaves are the swan-shaped gall and the club-shaped gall. These galls are all induced by gall midges of the genus Daphnephila (Diptera: Cecidomyiidae). Galls, the larvae of the inducers, gall size, and the general structures of the gall were studied and are described in this paper.
