SPIDERS (ARACHNIDA: ARANEAE) FROM SOUTHERN ROMANIAN LITTORAL OF THE BLACK SEA CLEOPATRA STERGHIU, C O S T I C ~ADAM Abstract. We present the results of the research on some spider specimens collected from the Southern Romanian littoral of the Black Sea. From the 21 identified spccies Metellitla segmentata (Clcrck, 1757) is mentioned for the first time fiom Dobrogea. Also, the species Nucteneo unlbrutica (Clerck, 1757) and Philodror~ilrscniorginahrs (Scluank, 1803) are mentioned kom Dobrogea for the second time, the first record being made by R o ~ c a(1938), but without exact specification of the collccting place. The species Lycosa singoriensis (Laxmam, 1770) is mentioned from the South of littoral area of Dobrogea for the first time. RisumC.

Kcy words: Araneae, fauna, Dobrogea, Southern Romanian littoral, the Black Sea.
Along the years, relatively a few studies on the spider fauna of Dobrogea were made. The first scientist who published several data on it was Alexandru R o ~ c a (1938, 1939). Later, in 1962, Cleopatra Oltean published data from several areas of Dobrogea, among them being Constants - Agigea (Southeastern Dobrogea), area which is also analyzed in this paper. In 1968, she published data on the spider fauna from Babadag Forest (Northeastern Dobrogea). Another scientist who made larger studies was Ion Fuhn, who, in 1971, published data from the Danube Delta and Popina Island (Razelm Lake) (Northeastern Dobrogea). In 1969, together with Cleopatra Oltean he published the results of a study on spiders from the Hagieni Natural Reserve (Southeastern Dobrogea). Also, data on the presence of some spider species in Dobrogea occur in the three volumes of "monograph" type of the series "Fauna Romdniei ' ("Romanian Fauna"). They deal with three spider families which were published as it follows: Lycosidae (Fuhn & Niculescu-Burlacu, 1971), Clubionidae (Sterghiu, 1985) and Salticidae (Fuhn & Gherasim, 1995). By this paper we try to bring some contributions for completing the data on the spider fauna from Dobrogea present as yet. MATERIAL AA'D METHOD
Our material was collected by some specialists of the "Grigore Antipa" National Museum of Natural History (Bucharest), during 17"' - 24'h of July 2003, from the Southern area of the Romanian littoral of the Black Sea. The collectings were made in the outskirts of the following localities: Agigea, Tuzla, Olimp and Saturn (Fig. 1). A number of 61 spider specimens were collected using the simple English translation by Mihaela Barcan Achim.

collecting technics, with the hand or the entomological net, as well the "Barber traps" method. The whole material was preserved in 75% alcohol. For the species identification we used the papers signed by Fuhn & Niculescu-Burlacu (1971), Sterghiu (1985), Locket & Millidge (1951, 1953) and Heimer & Nentwig (1991). Scientifical names of the species as well their taxonomical order are according to the catalogue of the world spider species published by Platnick (1998). RESULTS AND DISCUSSIONS
The 61 collected spider specimens belong to 21 species of 9 families, all of them included in the suborder Araneomorpha (Tab. 1). From the collected specimens, 12 belong to 5 different species, althought they couldn't be exactly identified, because all the specimens were juveniles, their identification being made at the genus level. From the 61 collected specimens, 19 are females (31.14%), 14 males (22.95%) and 28 juveniles (45.90%). In table 1, the families to which the collected and identified material belong are presented in systematical order, and within families, the species are ordered alphabetically, with their collecting data. As regards the diversity of the collected spider species we remarked that most of them belong to the families Araneidae ( 9 , Thomisidae (5) and Philodroinidae (3) (between brackets there is the number of the collected species) (Fig. 2). The rest of the material belongs to the families Tetragnathidae and Lycosidae, represented by two species each, and the families Pisauridae, Oxyopidae, Liocranidae and Clubionidae, by one species each. As regards the relative abundance of the individuals it can be remarked that the prevalent families are, by far, the Araneidae (57.37%) and Thomisidae (22.95%) (Fig. 3). This thing is due to that these families include mostly xerophilous species, well adapted to the steppe climate which characterizes also the Southern region of the Romanian littoral of the Black Sea. The other families were represented by a low number of individuals: Lycosidae (4.91%), Philodromidae (4.91%), Tetragnathidae (3.27%), Pisauridae (1.63%), Oxyopidae (1.63%), Liocranidae (1.63%) and Clubionidae (1.63%).

Fig. 3 -Relative abundance of the collected and identified spider individuals
The species Argiope bruennichi (Scopoli, 1772) was the most abundant from the number of individuals point of view, 27.86%, from the total of the collected specimens belonging to this species (Tab. 1). This Palaearctic species is very frequent in the studied area. As a matter of fact, among the collected and identified species, the Palaearctic species are prevalent (52.38%), a single species being Holarctic, and the others have a distribution range from Central and Southern Europe to Central Asia.

CLEOPATRA STERGHIU, COSTICA ADAM
If we make a comparison between the results of this study and the already known data, from the specialized literature mentioned in the beginning of the paper, as well the data from the two lists of the Romanian spiders, published by Fuhn & Oltean (1970) and Weiss & Petriqor (1999), we can assert that the species Metellina segmentata (Clerck, 1757) is mentioned from Dobrogea for the first time. Also, the species Nuctenea umbratica (Clerck, 1757) and Philodromus emarginatus (Schrank, 1803) are mentioned from Dobrogea for the second time, the first record being made by Roqca (1938), without specifying the exact collecting place. The species Lycosa singoriensis (Laxmann, 1770) is mentioned from the Southern littoral area of Dobrogea for the first time. ACKNOWLEDGEMENTS This study was made within the Project 6P12003 - "Biodiversity study of some coast, marine and terrestrial ecosystems from Southern Romanian littoral of the Black Sea, with conservation proposals", project chosen and financed by BALKAN ENVIRONMENTAL ASSOCIATION (B.EN.A) with funds from TUBORG-ROMANIA, which finances a programme of environmental projects and scholarships in Romania. We want to thank to the colleagues from "Grigore Antipa" National Museum of Natural History from Bucharest (Dr. Angela Petrescu, Rodica Serafim, Mariana Foaltin and Gabriel Chivamera) for putting the biological material at our disposal, as well to the anonymous scientifical referees for the useful advice on this paper.
