Taxonomical structure of the Chrysomelidae family consists of 43 genera and 138 species, representing about 64% from the total number of leaf beetles species known in the Maramure ş region and 24% from the Romanian chrysomelid fauna. Sclerophaedon carpathicus Weise, Chrysolina weisei (Frivaldszky), Psylliodes frivaldszkyi Weise and Neocrepidodera transsilvanica (Fuss) are Carpathian endemic species.

Maican – The Leaf Beetle fauna of the Rodna Mountains (123 ~ 140) INTRODUCTION The first information concerning the coleopterans from the Rodna Mountains, situated in the northern part of the Romanian Eastern Carpathians, were published in the second half of the XIX th century by Frivaldszky (1871) and Bielz (1887). A number of beetle species recorded from this area are found in the catalogues of Petri (1912, 1925). The Csiki’s paper (1951) presents a list with 1343 taxa (collected by the author, together with previous records for this area) from 56 families, including the Chrysomelidae family. Most of the chrysomelid species mentioned here were found on the southern mountainous slopes, on the tributaries of the Some şul Mare River: B ăilor Valley, M ăriilor Valley, valley of Ro şu Rivulet and Saca Valley. Szél et al. (1995) presents few leaf beetles species collected from Bor şa. Latest, some papers concerning the coleopterans from Maramure ş, also including the Rodna Mountains, were published by: Serafim (1997) - for Cerambycidae and Coccinellidae families; Proche ş (1998) - for Curculionidea; Stan (2002) - for Staphylinidae; Maican and Serafim (2001, 2004) and Maican (2007) - for Chrysomelidae; Nitzu et al. (2008), Merkl (2008). Investigations on the biodiversity of Maramure ş region and the National Park “Pietrosul Rodnei” were performed since 1995, within the “Knowledge of the invertebrates of Maramure ş” project, developed by the “Grigore Antipa” National Museum of Nature History of Bucharest. The objectives of this project were published by G ăldean and Pârvu (1997). Beetwen 1995 and 2004 several collecting trips were performed in Maramure ş area: the Maramure ş Depression, the catchment areas of the Iza, Mara and S ăpân ţa rivers, the Igni ş Plateau, the Ţible ş Mountains, the Maramure ş Mountains. Two expeditions were carried out in 1995 in the Pietrosul Rodnei Nature Park and on the valley of Iza River. MATERIALS AND METHODS The paper presents data about the distribution of the chrysomelid species in the Rodna Mountains, based on the study of the material collected during the expeditions made by “Grigore Antipa” National Museum’s team, in the period 1995-2004, and also on records from faunal papers published since 1887 up to 2008. The subfamilies within Chrysomelidae family are listed in the phylogenetic order, according to Seeno and Wilcox (1982). For each recorded species, the collecting sites and localities, the general distribution and the literature cited are given. The geographic distribution, the nomenclature and systematics are presented after Warchałowski (2003). The zoogeographical classification of the taxa is presented in accordance with information from the Gruev’s papers (2006 a, b).

E - European complex (CE - Central European; CEMount - Central European Mountain; Emount - European Mountain; SbM - Submediterranean; EsbM - Eastsubmediterranean); M - Mediterranean complex (HM - Holomediterranean; EM - Eastmediterranean). End - Endemic (CarpEnd - Endemic species to the Carpathians; AlpCarpEnd - Endemic species to the Alps and Carpathians). Transylv. Rev. Syst. Ecol. Res. 9, (2010), "The Rodna Mountains National Park" 125 RESULTS AND DISCUSSION On the basis of the information obtained until now, 138 chrysomelid species belonging to 11 subfamilies and 43 genera are reported from the Rodna Mountains, representing about 24.2% from the number of leaf beetles species mentioned in the Romanian fauna and 64.4% from the total species recorded in Maramure ş region (Tab. 1). Among them, aproximatively 26% are mountainous species (e.g. Chrysolina globipennis , C. hemisphaerica , C. carpathica , C. marcasitica , C. umbratilis , Oreina coerulea , O. intricata , O. Virgulata , O. viridis , Sclerophaedon carniolicus , S. carpathicus , Psylliodes glaber, Orestia aubei ). According to the information from the coleopterological literature, the following European endemics of the Alticinae have been recorded in the fauna of the Rodna Mountains: Orestia aubei , Minota carpathica , Longitarsus rubellus , Longitarsus pallidicornis , Neocrepidodera melanostoma and Phyllotreta christinae - all of them being distributed in most part of the European mountains. Neocrepidodera transsilvanica , Psylliodes frivaldszkyi , Chrysolina weisei and Sclerophaedon carpathicus are endemic species in the Carpathians. Also, Neocrepidodera cyanescens is endemic in the Alpine-Carpathian chain. Among the species mentioned in the older literature, Chrysolina weisei is a rare mountainous species, possible endemic to the Romanian Carpathians. The Minota obesa presence (Petri, 1912; from the Rodna Mountains) in the Romanian fauna is questionable. According to Gruev et al. (1993), the records of this species in Romania were possible based on the misidentified specimens of Minota halmae or M. carpathica .
