We were also given valuable comparative material from Mongolia (P. Surenkhorloo, Ulan Bataar), Kazakhstan (V. Devyatkov, Ust-Kamenogorsk) and Japan (S. Uchida, Toyota). All of these collections are presently kept at Schlitz in collection P. Zwick (PZ) and will eventually be deposited in a public museum. Comparative material was borrowed from the following collections: SAWL - Sächsische Akademie der Wissen- schaften zu Leipzig, Arbeitsgruppe Limnologie, Leng- feld, Germany; USNM - United States National Mu- seum, Smithsonian Institution, Washington, , USA; ZFMK - Zoologisches Forschungsinstitut und Museum Alexander Koenig, Bonn, Germany; ZIAS - Zoological Institute, Academy of Sciences, St. Petersburg, Russia In lists of studied material, capital letters E, L, P stand for exuviae, larvae, and pupae, respectively. Larval in- stars 1-4 are identified by the respective numeral fol- lowing the letter L. 3. KEY TO GENERA OF BLEPHARICERIDAE IN THE RUSSIAN FAR EAST The Far East Russian fauna comprises five genera. Ge- nus Neohctpalothrix Kitakami is endemic to the eastern part of Asia, its closest relative being the European ge- nus Hapalothrix Loew. The position of these genera in the family is doubtful - see under Neohapalothrix Kita- kami. The other four genera belong to tribe Ble- pharicerini and exhibit amphi-Pacific disjunctions, with close relatives in western North America. In the Palae- arctic Realm, Bibiocephala Osten-Sacken, Agathon von Röder and Philorus Kellogg are restricted to the eastern part of Asia, while Blepharicera Macquart is wide- spread in the northern hemisphere.
