Abstract Two new species ofthe gelechiid genus furtstenia are described from Japan.

Key words Gelechiidae, FZirtstenia, new species, Japan.

The genus Rxiistenia was established for Fkeniytenia omelkoi Ponomarenko, 1991 (type species) and its closely related species (Ponomarenko, 1991), and later its monophyly was supposed on the basis of two synapomorphies (Ponomarenko, 1997a). The adults of furistenia are externally similar to those ofthe genera H)/patihia HUbner, 1825 and Anat:si'a Zeller, 1839, however, PZittstenin can be separated from them by the presence ofhindwing hair pencils in the male. The genus is represented by 22species mainly distributed in the Palaearctic region (Ponomarenko, 1991, l997b; Park, 1993; Park & Ponomarenko, 1996; Li & Zheng, 1998), and five species were recorded from Japan by Park (1993) and Ueda et al. (1995). In this paper, we describe two new species of the genus lhristenia from Japan.

The terminology of the male genitalia mainly fo11ows Ponomarenko (l991), The term valvella which was proposed by Birket-Smith (1965) for the arctiid subfamily Lithesiinae was used fbr the basal lobe of the valva which is also recognized in the genus H)/patima and its related genera (Ponomarenko, 1992, 1997a). This lobe has been called various terms, viz., labides (Diakonoff 1967) and sacculus (Sattler & Stride, 1991). The orig{n ofsuch lobes in different groups within Lepidoptera is uncertain and actually Ponomarenko (1992) pointed out that further investigations are necessary to clarify the homology ofvalvella in Gelechiidae to that in Lithosiinae. In this paper, we tentatively use the term valvella for the basal lobe of the valva. The definition of valvella fbllows Tuxen (1970), The terminoiogy of the female genitalia is taken after Klots (1970).

Remarks. E kanazawai sp. n, resembles E geminisigneiZLx Ponomarenko, 1991 superficially, but it can be distinguished from the latter by the lack of a large elliptical blackish mark on the plical fbld. The male genitalia ofthis new species are simiiar to those ofE cornutivatva- ris Li & Zheng, 1998. Howeyer, E kanazawai sp. n. differs from E cornuttvaisariy by the fo11owing characters: the posterior margin ofthe uncus is evenly rounded and the lobe ofthe juxta is shorter than half of the valvella, while in E cor:nuttvatvar:is the posterior margin of the uncus is convex at middle and the lobe ofthejuxta is longer than halfefthe valvella. In the male genitalia, E kanazawai sp. n. is also similar to II thangukx Li & Zheng, 1998, but

it is distinguishable from the latter by the evenly reunded posterjor margin ofthe uncus and the triangular median plate on the ventral margin of the valva, while in E triangula, the posterior margin of the uncus is convex at middle and the ventral margin of the valva is expanded into the semicircular plate at near middle.

Distribution. Japan (Honshu).

Host plant. SZzpindus mukurossi Gaertn. (Sapindaceae),

Remarks. E mukurassivora sp. n. is closely related to E medimacuima Li & Zheng, l998, but it is distinguishable from the latter externally by the lack of a large trapezoidal black blotch at middle on the costa of fbrewing. In the male genitalia E mukurasstvora sp. n. is separable from E medimaculata by the rounded posterior margin of the uncus, the presence of bristles along the ventral margin of the valva and the presence of a longitudinal plate on the ventral surface before the middle, while in E metfimacuiata the posterior margin of the uncus is produced into a knob at the middle, the valva lacks bristles along the ventral margin and the ventral margin of the valva expands into a triangular plate at the proximal end. In the female, this new species is separable from the other congeners known from Japan and Russian Far East at present time by the sclerotized pleural region between the 6th and 7th abdominal segments.
