FOUR NEW FOR THE LITHUANIAN FAUNA GEOMETRID(LEPIDOPTERA, GEOMETRIDAE) SPECIES

Abstract. This article deals with 4 new for the Lithuanian fauna geometrid (Lepidoptera, Geometridae)species: Orthonama obstipata, Peribatodes secundaria, Hydriomena ruberata, and Eupithecia ochridata.For each species, information on capturing locality and date, the number of collected specimens, theirsex and habitat is presented here. Totally, 304 geometrid species have been registered in Lithuania.Key words: Lepidoptera, Geometridae, distribution, Lithuania.

I NTRODUCTION

Six years have passed since a check-list of LithuanianLepidoptera has been published (Ivinskis, 1993). Af-terwards, some more data about new and rare for theLithuanian fauna Lepidoptera species was published(Dapkus, 1995; Ðvitra, 1995). The Moth Monitoringproject (Soderman, 1994) which has been held inLithuania since 1995 and our intensive studies through-out Lithuania during 1991-1998 have revealed 4 newfor the Lithuanian fauna geometrid species.

MATERIAL AND METHODS

Light traps with DRL 250W lamp bulbs were used toattract the moths. Some of the material was collectedwith Jalas model automatic light traps where 160Wmixed light bulbs were used.All species were identified according to their genitaliastructures. The abdomens of the specimens weremacerated in 10% NaOH for 24 hours in a room tem-perature and were studied with the help of a binocularmicroscope MBS-10. The nomenclature was used fol-lowing Müller, 1996. The collected material is nowkept in personal collections of the authors.

RESULTS

Four new for the Lithuanian fauna geometrid (Lepi-doptera, Geometridae) species were found during theperiod of research.

Hydriomena ruberata (Freyer, 1831)

Ðvitra; Plungë Region, Plokðèiai village,05-12 06 1995, 4FF; 22-29 05 1995, 5FF; 27 05-03 06 1996, 7FF; 03-10 06 1996, 3FF; 10-17 061996, 1F, leg. D. Dapkus. The specimens were foundin the territories, which were overgrown with bushesalong water bodies and swamps. They usually fly to-gether with H. impluviata. This species is not rare inEstonia (Viidalepp, pers. comm.). It also occurs inmountains in the southern part of Poland (Buszko, pers.comm.). In other neighbouring countries, such asLatvia and Byelorussia it was also found (Merzhe-yevskaja et al., 1976).

Orthonama obstipata (Fabricius, 1794) Tauragë Region, Vieðvilë Strict Nature Reserve, 25 071994, 1F; 27 06-03 07 1995, 1F; 04-11 07 1995,1F; 11-17 07 1995, 1F; 18-24 07 1995, 1F; 20-2507 1998, 1F, leg. V. Uselis; Plungë Region, Plokðèiaivillage, 5-12 08 1996, 1F, leg. D. Dapkus. The habi-tats are alder swamp woods nearby wet fir-groves.As regards neighbouring countries, this species isknown from Estonia and Poland (Müller, 1996).

Eupithecia ochridata Schütze & Pinker, 1968

Ukmergë Region, Kertuðas village, 11-18 06 1995, 1F;16-23 07 1995, 1F, leg. G. Ðvitra; Tauragë Region,Vieðvilë Strict Nature Reserve, 25-31 07 1995, 1F,leg. V. Uselis. The habitat is a boundary between a fir-grove and a wet meadow. This species is consideredto be a migratory species. The year of 1995 was agood year for migration therefore, O. obstipata wascaught in Latvia (Ðulc, Savenkov, 1996), Estonia(Viidalepp, 1996), and Western Russia (Lundsten, 1996)as well. As regards neighbouring countries, this spe-cies is known from Poland and Byelorussia (Merzhe-yevskaja et al., 1976).

Ferenca.The habitats are the edges of mixed and deciduous for-ests. E. inno-tata and E. ochridata are considered tobe sibling species so it is problematic to identify them.Future studies of both species are necessary. As re-gards neighbouring countries, this species was foundin Latvia (Müller, 1996), Estonia (Viidalepp, pers.comm.), and Poland (Buszko, pers. comm.).

CONCLUSIONS

1. Since 1993, the list of Lithuanian geometrids (Lepi-doptera, Geometridae) has been enriched with fourspecies. These are Orthonama obstipata, Peri-batodes secundaria, Hydriomena ruberata, andEupithecia ochridata.

2. Taking into account the corrections in taxonomyof Geometridae in the check-list of European Lepi-
