Two species of Gracillariidae (Lepidoptera) new to China, and description of the pupal morphology of the genera Corythoxestis and Eumetriochroa Author Kobayashi, Shigeki Author Huang, Guo-Hua Author Hirowatari, Toshiya text Zootaxa 2011 2892 25 32 journal article 46825 10.5281/zenodo.204720 c215e0b1-ea1b-4c09-9a9b-241fbabffd12 1175-5326 204720 Eumetriochroa hederae Kumata, 1998 Figs. 1 C, 2M–O. Eumetriochroa hederae Kumata, 1998 : 85 –89, figs 1, 2A, 12(A, B), 14(A), 17, 18(A), 22(A), 24(A,B). Type locality: Japan (Fukuoka). Diagnosis. Antennal scape with a large scaly pecten. Forewing ocher brownish in ground color with five whitish fasciae. Male genitalia without a thorn-like apical seta; aedeagus with a long cornutus. Female genitalia with trapezoid seventh abdominal segment ( Kumata 1998 ). Pupa. ( Fig. 5 ). Brown, 5.0–6.2 mm in length, 0.8–1.0 mm in diameter. Vertex with a spade-like frontal process (cocoon cutter), acutelly elevated centrally. Antenna long and straight, extending over A10. Dorsum of A2–A10 with a concentration of small spines except for median part. A10 furcated with a pair of digital processes from caudal apex with small acute processes at apex ( Fig. 5 L); another pair of anteriorly curved, small caudal ones from dorsal side ( Fig. 5 K). Host plant. Hedera nepalensis var. sinensis (Tobl.) Rehd. (new record); Hedera rhombea (Miq.) Bean ( Kumata 1998 ) in Japan , Araliaceae . FIGURE 4.

Hirowatari & Guo-Hua Huang (genitalia slide no. OPU-SK174, 175), Host: Hedera nepalensis var. sinensis , 27.v.2009 (larva) (HUNAU, OPU). Biology. Kumata (1998) recorded the biology of this species in Japan . In the present study, we observed the larva forming yellowish green serpentine mine on leaf of Hedera nepalensis var. sinensis . The mines ( Fig. 2 M–O) were found on the upper side of leaves and were entirely subepidermal, usually one mine per leaf. Remarks. This species is easily distinguished from other Eumetriochroa species by the characters summarized in the diagnosis. We describe the pupal morphology of this species for the first time based on Japanese specimens: 26 exs, Konagao, Soni, Nara Pref., Japan (S. Kobayashi leg.), 14.iii.2010 (larva). We could not recognize any difference in the pupal morphology between Chinese and Japanese specimens.
