Faunistical records of larvae of Ephemeroptera, Odonata and Plecoptera from the Zakarpats'ka Region, Ukraine

This paper provides data on 45 Ephemeroptera, 6 Odonata species and 8 Plecoptera taxa from the Zakarpats'ka Region, Ukraine. The species Baetis tracheatus, Rhithrogena beskidensis, Paraleptophlebia werneri and Brachyptera risi are recorded in the first time from Ukraine. The following species are new to Zakarpats'ka Region and Tysa River: Baetis tricolor, Procloeon pulchrum, Electrogena affinis. The pupae of Symbiocladius rhithrogenae (Zavr4el, 1924) (Diptera: Chironomidae) were found on a few specimens of R. beskidensis. The data provided in this paper come from two sources. The majority is the results of a fau- nistical research focused on the Tysa river and its tributaries carried out in 6-7 May 2004 and 29-30 June 2004. The water sourses investigated are Chorna Tysa, Bila Tysa, Tysa (six sam- pling spots), Shopurka, Apshytsia, Teresva, Tereblia, Rika, Borzhava. The other four data are from the section of Bratovo (Batar) and Palad' (Palad-patak) that represent the frontier between Ukraine and Hungary. Methods of collecting see in KOVACS et al. (1998), the collector is Tibor Kovacs. The Ephe- meroptera and Plecoptera material on which the present study is based has been preserved in 70% ethanol and housed in the Matra Museum (Gyongyos, Hungary). Some specimens each of the species new to Ukraine are deposited in the State Museum of Natural History, National Academy of Sciences of Ukraine (SMNH). Identification of the genera Plecoptera: Isoperla, Chloroperla, Siphonoperla, Amphinemura, Nemoura, Protonemura, Leuctra is still in progress. Larvae of Dinocras and some Perla spe- cies are quite difficult to identify. Therefore in the list of data the name Dinocras cephalotes- megacephala and Perla marginata-pallida complex are applied. The geographical and administrative names are transliterated from Ukrainian according to official Ukrainian-English transliteration system (adopted by the Ukrainian Legal Termino- logy Commission (Decision N 9): http://www.rada.gov.ua/translit.htm).
