The genus Metendothenia Diakonoff .1973 is a small genus ef the tribe Olethreuti nwiidely distribut eidn the world except Australi aN,ew Zealand and South America, and seventeen species have been recorded globall y(Brow n2,005) ,The genus has a valva with a setose lobe on the posterio ernd of the costa of thc valva i'n the male genitali a(Razowsk i1,989). Three species have hithert boeen recorded from Japan (Kawabe ,1978, 1982, 1987; Jinbo, 2004-2007). In July 2005, one of us, Tbminaga discovered unfamiliar olethreuine larvae feeding on the leave sofDixpetes matsumuiue (Euphorbiace aeTh)e. emerged moths are referable to Metendthenia mesarotra (Meyrick )whi,ch previousl wyas recorded from Java and the So]omon Is .

Scxual dirnorphism is pronounced ;the male hind wing has a protrudin ganal roil, pointed distall ya,nd a swollen dorsum between the marginal points of Cup and IA+2A (Fig ,1) .The male genital iarae characterized by a slender uncus with several thick setae on the top and blade-shape vdalva with a large curved lobe with many thick setae on the poste- rior end of the costa (Fi g7,) .The female genital iaare characteriLed by a depresse doval sterigma with a ventral groove and a circular signum in the cerpus bursae (Fi g8.) .The species is distinguishabl efrom it scongeners in Japan by the olive triangular patch on the dorsum and the blade-shaped valva with a pointe dapcx.

Metendothenia organica (Meyric k1,920) has been regarded as ajunior synonym of M. mesarotva (Diakono f1f9,73; Brown, 2005) .This treatment was originally adopted by Diakonoff (1973) h;owever, he (1982 )late rcorrected this, concluding that M. onganica is an independent species because of difTerence sin the structures of the female genitalia. Judging from the figure of female genital iofa M. organica by Diakonoff (1982 )i,t is clearly distinguisha bflreom those of M. mesarotiu in the sterigma and signum, Acknowledgment We thank Mr M.
