The adult and genitalia of the both sexes are illustrated and redescribed. Key words Gelechiidae, DendiophiiZtz (Dencbmphiha) athidlede (Sne}len), new record, Japan. The genus Dendrophiha was proposed by Ponomarenko in 1993 on the basis of the type species ?Vbthnls athidle2Zti Snellen, 1884. Up to the present, 22 species were assigned to the genus by the previous authors (Ponomarenko, 1993, 1997; Ueda et al., 1995; Park. 1995; Park & Ponomarenko, 1996; Li & Zheng, i998; Lj, 2oo2) from Russia, Korea, Japan, China, Taiwan, Jndonesia and India. Five Denthophilla species were recorded fragmentarily from Japan (Moriuti, 1982; Kanazawa et al,, 1984; Park, 1995; Ueda et al., 1995; Mano & Harata, 1997; Ponomarenko, 1997). Kawahara (2000) recorded DendeophiZiti saxigera (Meyrick) from Hokkaido and illustrated the adult. As a result of reexamining the speci- mens identified as D. saxigera (Meyrick) collected frorn Hokkaide, we concluded that they were not true n scLxigeva (Meyrick) but an unrecorded species from Japan, Denthtophfiffa (Dendrophilic) athideha (Snel]en), In this paper, we redescribe and illustrate the adult and genitalia of the both sexes of D. (D.) athidledo (Snellen), Fig. 1, Adult of Dendhophititr (Dendhophitla) athidledo (Snellen, 1884). * Present address: Chiiki-Kankyo-Keikaku Co., Midoriakutagawa Building, I-15-18, Akutagawa- cho, Takatsuki City, Osaka, 569-1123 Japan NII-Electronic LibraryMbrary Service The Lepidopterological Society of Japan Dendtophtiia (Dendrophtha) athidbtla from Japan 121 The terminology of genitalia is main]y referred to Ponomarenko (1993).

Kawahara (2000) noted that this species was collected in a coastal aiea in Koshimizu Town, Hokkaido, Most of specimens examined in this paper were collected near the seaside. Remarks. D. (D.) athidbi?ti is separable from the other Japanese Dendrophtha species by the creamy white color of the fbrewing. In the male genitalia, D. (D.) athidlado is allied to D, (n) neotaphronoma Ponomarenko, 1993, but those of D, (D) aloideha difler from the latter by the somewhat long gnathos and slightly sinuate valva. The shape ofvalva differs slightly from the figure of Ponomarenko (1993), but this difference may be the geographical or individual variation, The female genitalia are characteristic in having the large signum. D. (D.) athideZla is recorded frorn Japan for the first time. Acknowledgments We express our hearty thanks to Dr Y.
