Abstract ffbndecanetfva himaga),ana Nasu, n. sp., a clese ally of HL cndotima (Meyrick), is described from Nepal and India (Sikkim). RL axiotima is newly recorded frorn Nepal and India (Sikkim). The adults and the genitalia of both species are illustrated.

Key words Hendecaneuva hiinugayana Nasu, n. sp., Lfbndecaneura cLxiotima (Meyrick), the Himalayan range, genitalia, Tortricidae.

I exarnined a short series of tortricids identified as Ifendecaneza7u exiotima (Meyrick) from Nepal and India (Sikkim) at the Natural History Museum, London, UK (BMNH), and concluded that it consists of two species, U axiolima and a new species. In the

following lines the description of the new species and distinguishing characters between them are given, with illustrations of adults and genitalia, All materials are deposited in BMNH.

’ Kuzneztov （1973）gave the illustrations of the male and female genitalia of ax iotima based two specimens and ユ also cited on from China （Yunnan ）， Razowski （989b ） his illustration ’ of female gen ｛talia under axiotima ． Of Kuznetzov s 川 ustrations the male one is similar to of czxiotima one of n ． sp ． rather the genitalia ， but the female to the genitalia himalayana than those of aTiotima in having the tergite 8 with concave anterior edge the smaller ， corpus bursae and the signa different in size ． It is quite possible that the female specimen examined by Kuznetzov is not axiotima but himalayana n ． sp ． 正／ axiotima was recorded from Taiwan by Kawabe et al ．（1992）in the checklist of the Lepidoptera of Taiwan ， but the data of voucher specimen （s）have not been described ．
