Two Species Of Gracillariidae (Lepidoptera) New To China, And Description Of The Pupal Morphology Of The Genera Corythoxestis And Eumetriochroa

The subfamily Oecophyllembiinae (Gracillaridae) is reported from China for the first time. Two species, Corythoxestis sunosei (Kumata, 1998) (host plant: Mussaenda esquirolii H. Lev. 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 differences from other genera of Oecophyllembiinae and Phyllocnistis. Corythoxestis sunosei has a unique frontal process flanked by two long processes with a pair of setae, and both C. sunosei and E. hederae have a cremaster with two pairs of caudal processes.
