FOLIA ENTOMOLOGICA HUNGARICA ROVARTANI KÖZLEMÉNYEK LUI 1992 p. 93-111 Collembola from North Korea, II * Entomobryidae and Tomoceridae By Lee Byung-Hoon and Park Kyung-Hwa (Received March 31, 1992) Collembola from North Korea II. Entomobryidae and Tomoceridae. - 18 species of Entomobryidae and Tomoceridae fom North Korea, including 2 new species and 3 new records for the Korean peninsula are discussed. Pogonogiathellw was found to be the genus of new record, whereas 13 species on record are in addition. Overall affinity of Korean Entomobryidae, however, is revealed to be a little stronger with the Japanese fauna rather than between the North and South Korean forms. The present study eventually resulted in listing 28 species in 4 genera of Entomobryidae and 19 species in 2 genera of Tomoceridae as members of the Korean fauna. INTRODUCTION North Korean Collembola were studied by several authors including one of the present authors (Szeptycki 1973, Lee and Thibaud 1975, Mari Mutt 1983, Deharveng and Weiner 1984, Weiner and Najt 1985a, 1985b, Nait and Weiner 1985, Weiner 1986a, 1986b, Weiner 1989). As far as Entomobryidae are concerned, however, it was Szeptycki (1973) and Mari Mutt (1983) who dealt with Entomobryidae first from North Korea, uncovering six Homidia and three Orchesellides species respectively, all as new to science even though, the same family was treated more extensively from South Korea by some Korean and Japanese taxonomists (Yosii and Lee 1963, Yosii 1966, Lee and Lee 1981, Lee and Park 1984) which gave rise to ten species as new to science and seven new records for the Korean Peninsula. In all, the Korean entomobryid Collembola comprise 26 species in 4 genera, that is, 9 species in 2 genera from North and 17 species in 3 genera from South Korea. As regards Tomoceridae no reports have ever been made from the North so fan Several Japanese as well as Korean authors reported the occurrence of 17 speces in one genus (Kinoshita 1932, Yosii and Lee 1963, Yosii 1966, Lee 1973, 1974, 1975) from South, in addition to one species described by Kinoshita (1932) wherewith no collection locality was specified. The situation with Tomoceridae, known only from South Korea, may be partially explained by the rigorous political break off between Nort and South during last forty years, which never allowed South Korean collembologists to study the northern * Zoological Collectings by the Hungarian Natvral History Museum in Korea, No. 113.
