The Nygmiini is a tussock moth tribe which is redominantly distributed in most regions of the Old World. It was established in order to accommodate several genera that were previously associated with the polyphyletic genus Euproctis Hübner, 1819, which was erected upon the western European Euproctis chrysorrhoea (Linnaeus, 1758)(=Phalaena chrysorrhoea) and has included 682 valid specific names since the early 19th century. The caterpillars of Nygmiini are fairly polyphagous on various woody plant families, and thus many of them are considered as pests with significant importance. They are also known for having importance in public health due to the strong allergic reaction caused by the urticating setae. Although the tribe Nygmiini as well as the core genus Euproctis has such importance in various aspects, it¡¦s monophyletic status and phylogenetic relationships have never been tested using modern phylogenetic methods. I therefore sampled 175 lymantriid species representing most of the potential members of Nygmiini plus one arctiid species as the outgroup taxon to reconstruct the phylogeny of this tribe based on morphological characters from all development stages. The results suggest that the tribe Orgyiini forms a monophyletic clade with the Nygmiini, while neither the Nygmiini sensu Holloway nor the genus Euproctis sensu auctorum is monophyletic, and thus the taxonomic boundary of the tribe should be redefined in accordance to the hypothesis proposed by the present study. On the other hand, larval characters become the major source of the synapomorphies of the Nygmiini. The adult wing patterns which are used to taxonomic identification, however, are highly convergent among genera and thus these characters are not supposed to be informative in systematic research.

Drugiai Lietuvoje tiriami jau seniai, tačiau dažniausiai tai buvo epizodiniai tyrimai. Yra mažai duoneų apie konkrečios vietovės drugių bendrijas. Šiame darbe aprašomi Ignalinos rajono, agrarinio kraštovaizdžio naktinių makrodrugių tyrimų metodai ir rezultatai. Tirti drugiai priklauso antšeimiams Geometroidea, Bombycoidea, Drepanoidea, Lasiocampoidea, Noctuoidea ir Hepialoidea. Tyrimų medžiaga buvo renkama 2008-2010 m. Antagavės ir Stagalėnų apylinkėse (Ignalinos rajonas), nuo gegužės iki lapkričio. buvo naudojama Jalo modelio šviesinė vabzdžių gaudyklė su Philips ML 160W lempa. Marinimui naudotas etilacetatas. Antagavėje buvo rastos 169 drugių rūšys, Stagalėnuose 201, surinkti iš viso 13244 individai. Stagalėnai yra Aukštaitijos nacionaliniame parke. Šiose apylinkėse rasta 33% visų parke žinomų drugių rūšių. Nenustatyta eudominantinių ir dominantinių rūšių. Gausiausios rūšys buvo Rivula sericealis (sudarė 3,89% visų bendrijos individų), Xestia (Megasema) c-nigrum (3,41%), Caradrina (Caradrina) morpheus (3,12%). 26 rūšys sudarė daugiau nei 1% visų bendrijos drugių individų. Gausiausios rūšys Antagavėjė buvo Noctua pronuba (7,96%) ir Caradrina morpheus (6,39%). Tai dominantinės rūšys šioje vietovėje. Didžiausias drugių rūšių ir individų gausumas buvo liepos mėnesį. / Lithuanian moths (Lepidoptera) were studied by various researchers for a long time, but mostly only episodic studies were carried on. There are little data concerning nocturnal Lepidoptera investigations of concrete district. Methods and results of nocturnal macrolepidoptera research in agricultural landscape in Ignalina administrative district are described in this work. Analyzed species belong to superfamilies Geometroidea, Bombycoidea, Drepanoidea, Lasiocampoidea, Noctuoidea and Hepialoidea. The material of nocturnal Lepidoptera was collected in Antagavė and Stagalėnai localities (Ignalina administrative district) during May and October 2008-2010. Jalas model automatic light trap with Philips ML 160W lamp bulb was used. Ethyl acetate was used as a killing agent. There were 169 moth species collected in Antagavė and 201 in Stagalėnai with the total number of 13244 individuals. Stagalėnai is in Aukštatija national park. In this village found 33% of the national park known species. There was no eudominants or dominants. The most abundant species were Rivula sericealis (species made 3,89% of all individuals in Stagalėnai), Xestia (Megasema) c-nigrum (3,41%), Caradrina (Caradrina) morpheus (3,12%). 26 macrolepidoptera species made more than 1% of all individuals. They characterise the community. Most abundant species in Antagavė were Noctua pronuba (7,96%) and Caradrina morpheus (6,39%). They are dominants in this territory. Greatest abundance of species and individuals was... [to full text]
