The subfamily Oecophyllembiinae (Gracillaridae) is reported from China for the first time. Two species, Corythoxestissunosei (Kumata, 1998) (host plant: Mussaenda esquirolii H. Lév. Rubiaceae) and Eumetriochroa hederae Kumata, 1998(host plant: Hedera nepalensis var. sinensis (Tobl.) Rehd., Araliaceae), are recorded from new host plants from Hunan, China. Pupae of the genera Corythoxestis and Eumetriochroa are described for the first time. We found three diagnostic differencesfrom other genera of Oecophyllembiinae and Phyllocnistis. Corythoxestis sunosei has a unique frontal process flanked by twolong processes with a pair of setae, and both C. sunosei and E. hederae have a cremaster with two pairs of caudal processes.
