The Macrolepidoptera (Insecta: Lepidoptera) from Istriţa Hill (Buzău County, Romania) Vlad Dincă1 1Gheorghe Doja street, no. 5 bl. 36 C2, ap. 44, Ploieşti, RO-100400 article no.: Entomologica romanica 10: 5-24, 2005 Rezumat: Subcarpaţii României şi în special Subcarpaţii Curburii, reprezintă o veritabilă „pată albă” din punct de vedere lepidopterofaunistic. Prezenta lucrare cuprinde rezultatele cercetărilor asupra macrolepidopterelor din zona Dealului Istriţa (jud. Buzău), efectuate în perioada aprilie 1996-septembrie 2005. Printre cei 521 taxoni identificaţi se numără o serie de specii valoroase din punct de vedere zoogeografic, puţin cunoscute de pe teritoriul României sau chiar al Europei, precum: Hipparchia volgensis delattini Kudrna, 1975, Scotopteryx ignorata Huemer & Hausmann, 1998, Cucullia fraterna Butler, 1878, Euxoa vitta (Esper, 1789), Euxoa hastifera pomazensis Kovács, 1952, Aedia leucomelas (Linnaeus, 1758) Chrysodeixis chalcites (Esper, 1789), Dichagyris candelisequa ([Denis & Schiffermüller], 1775), etc. Dealul Istriţa (749 m) se remarcă în mod special prin prezenţa versanţilor calcaroşi cu expoziţie sudică care reprezintă habitatul optim al unor specii de lepidoptere termofile şi xerotermofile cunoscute din foarte puţine localităţi ale României. Pe lângă asemănările semnificative cu lepidopterofauna Dobrogei, datele prezente în lucrare atestă existenţa unei continuităţi între lepidopterofauna din sud-estul şi cea din sud-vestul ţării noastre, continuitate realizată la nivelul dealurilor subcarpatice, în condiţiile în care regiunile de câmpie au suferit şi suferă încă transformări profunde datorate puternicelor presiuni antropozoogene.

Clinicilor 5-7 article no.: Entomologica romanica 10: 37-42, 2005 Summary: 1. Were examined the community structure indices (dominance, similarity, diversity) of carabid beetles and spiders in the peat bog Mohos in the East of Transylvania (Romania). 2. Studies were carried out in four different habitats: in Scoth pines forest, in birch forest, in meadow and in the nearest beech forest. 3. During the survey the peat bog carabid fauna were the purest (84 specimens belonging to the 17 species) and the beech forest fauna were the richest (606 specimen belonging to the 21 species), while the spider fauna were represented inverse (546 specimens and 48 species in peat bog and 119 specimens and 12 species in beech forest). 4. We can conclude that the habitat structure (soil types, plant cover) and the disturbances have a significant role in forming the dominance of species and also the diversity and the similarity of the communities are highly influenced Key words: Carabidae beetles, spiders, beech, pine, birch, meadow, diversity, similarity. e-mail: matheistvan@sapientia.siculorum.ro, kui@email.ro, balogadalbert2002@yahoo.co.uk	[details, abstract]	[pdf]

Au dominat speciile de Longitarsus şi Cryptocephalus, au fost de asemenea bine reprezentate genurile Phyllotreta, Cassida şi Chrysolina, iar cele mai multe genuri au fost reprezentate prin doar 1-2 specii. Dintre subfamilii, au dominat Alticinae şi Chrysomelinae, iar Cryptocephalinae a fost de asemenea mai bine reprezentată. S-au evidenţiat de asemenea un număr de 21 de specii de crizomelide care pot fi considerate rare, cu statut de periclitate.

Site fidelity and fluctuating asymmetry in males of Libellula fulva (Odonata: Libellulidae) Beáta Nagy1, Annamária Székely1 & Noémi Szállassy1 1Department of Taxonomy and Ecology, Babeş-Bolyai University, RO-400006 Cluj Napoca, Clinicilor str. 5-7 article no.: Entomologica romanica 10: 59-64, 2005 Summary: During two seasons (2002-2003), a closed Libellula fulva (Müller, 1764) population was studied along a small, canalized creek in Eastern Hungary. The territorial behaviour of males was observed with the mark-recapture method. A number of 169 males were marked in 2002, and 186 males in 2003. The movement of marked males was observed with binoculars, and was recorded along a 350 meter natural section of the stream that was marked every five meters with numbered sticks. The site fidelity of males was studied with the localisation index (LI) and site fidelity index (SFI). We found that the SFI of males that simultaneously defended three territories was high, while the LI was highest in the case of males that protected only one area. The purpose of the study was to see if male’s site fidelity is related to wing asymmetry and body size. There was no correlation between male’s site fidelity and the measure of wing asymmetry in 2002. In 2003, however, a significant correlation was found in the case of males which defended only one territory. There was no correlation between body size and SFI.

Contributions to the knowledge of the genus Edwardsiana Zachv. (Hemiptera: Cicadomorpha: Cicadellidae: Typhlocybinae) in Romania Valentin Popa1 1„Babeş – Bolyai” University, Department of Taxonomy and Ecology, Clinicilor 5-7 Street, 3400 – Cluj Napoca, Romania article no.: Entomologica romanica 10: 71-79, 2005 Summary: This article represents an overview about the occurrence of some Typhlocybin species belonging to the genus Edwardsiana Zachv. in Romania. There are fifteen species belonging to this genus so far recorded in the fauna of Romania. Basing mainly on our recent studies and also on literature data, we found that within fifteen previous records, twelve are reliable and three are unreliable. The unreliable data refer to E. kemneri (Ossian.), E. lethierryi (Edw.) and E. frustrator (Edw.) probably misidentified due to male parasitisation. Three species belonging to the genus Edwardsiana Zachv. are recorded for the first time in Romania: E. avellanae (Edw.), E. spinigera Edw. and E. ulmiphagus (Wils. & Clar.); two species for the first time in the fauna of Transilvania: E. ampliata (Wgn.) and E. prunicola (Edw.). According to the occurrence of some Edwardsiana Zachv. species in the neighbouring countries, we should expect a presence in Romania of at least thirty.
