The Entomobryidae comprising one new record from Korea, six new species (4 Entomobrya, 2 Homidia) and a cave form of Sinella genus have been studied. One of the Entomobrya comes from cone pines, hence considered an arboreal species. The present study brings Korean faunal list of Entomobryidae to 23 species in 3 genera, of which 16 are endemic to the country.

We report three collembolan species in Entomobryidae previously unrecorded from Korea: Homidia socia Denis and Homidia nigrocephala Uchida from aquatic or semiaquatic habitats, and Entomobrya tokunakai Yosii from several forests. These species are redescribed.

Six species of springtails (Collembola) are reported for the first time from North Korea: Pachyotoma takeshitai (Kinoshita, 1916), Folsomia bisetosa Gisin, 1953 and Agrenia agilis Fjellberg, 1986 of Isotomidae, Entomobrya sibirica Stach, 1963 and Willowsia buski (Lubbock, 1870) of Entomobryidae, and Ptenothrix setosa (Krausbauer, 1898) of Dicyrtomidae. The genus Pachyotoma Bagnall, 1949 is mentioned for the first time from the Korean Peninsula. In order to facilitate the identification of these species, illustrations and short diagnoses are provided and the poorly known P. takeshitai is described in detail. Ptenothrix setosa and E. sibirica link the Korean peninsular fauna with Central Asia, P. takeshitai shows the zoogeographical connection of the Korean Peninsula with the Japanese Islands and A. agilis has a trans-pacific distribution. Folsomia bisetosa is an interesting circumpolar element in the Korean fauna while W. buski is a subcosmopolitan species.

한국산 털보톡토기과(Collembola, Insecta)의 계통유연관계를 알아보기 위해 이 과에 속하는 3개속(Sinella, Entomobrya, Homidia)의 6종과 가시톡토기과의 1종(Tomocerus kinoshitai)에 대하여 모서식과 형태적 조사 외에 전기영동을 이용한 효소분석을 시리시하였다. 이들 모든 조사에서 32개의 형태형질과 33개의 모서식형질 및 80개의 효소유전자 형질을 얻어 분지분석하였는데, 이중 효소유전자에 대해서는 UPGMA방법도 적용하였다. 이러한 분석 결과 다양한 분지도를 얻었으나, Homidia종들은 언제나 두 개의 무리로 분리되었으며, Homidia munda의 두 아종이 가장 유연관계가 높았다. 반면에 Homidia koreana의 두 개체군은 다소 분리되어 같은 종으로 보기 의심스럽다는 소견을 얻었다. 또한 형태형질분석으로 얻은 계통수에서 가시톡토기과의 Tomocerus종이 털보톡토기과의 속들 사이에 끼어들어 나타나는데 이것은 형질에 따라 비중을 달리두는 평가방법이 아니기 때문에 나타난 것으로 추측된다. 본 연구 결과 대체로 외부형질과 모서식, 그리고 효소유전자의 세가지 유형의 형질들을 종합 분석할 때 도출되는 계통수가 자연분류에 가장 가까운 근연성을 보이는 것으로 판단되었다.

In order to understand affinities and phylogeny of three families of the Superfamily Entomobryoidea allozyme analysis was performed with three species presumably representing each family, in addition to four species belonging to the neighboring Superfamily Poduroidea together. Electrophoresis for this purpose produced data for calculating allele frequency and enabled to obtain genetic distance and to depict dendrograms as well. The species of Isotomidae, Entomobryidae and Tomoceridae were clustered together whereas those of Hypogastruridae, Onychiuridae and Neanuridae were grouped as monophylies, respectively. Even though Tomoceridae and Entomobryidae were brought together they are considered complete families by showing high genetic distance value between them, thus supporting the hypothesis on their affinity among others. Gulgastrura reticulosa has been revealed to be separated from Hypogastruridae by being clustered rather with Onychiuridae. However, its high genetic distance value suggests the status as an independent family. The present result agreed with the phylogeny of Suborder Arthropleona divided into two Superfamilies mentioned above as in conventional systematics and also when compared with analysis of data of their morphological characters as well as 18S rDNA performed and published elsewhere by the present writers.
