한국산 유각변형충목(Arcellinida) 및 유각사상근족충목(Gromiida)을 분류학적으로 연구하기 위하여 1988년 8월부터 1990년 10월까지 남한의 9개 지역에서 각종 담수지역으로부터 재료를 채집하고, 광학현미경 및 주사전자현미경을 사용하여 관찰하였다. 그 결과, Arcello gibbosa, A. polyporo, A. dentata, Centropyxis oculeata, C. ecomis, Nebela dentistomo, Lesquereusia modesty, 1. spirolis, Netselia tuberculata, Dinugio ocuminota, D. corona, D. crosse, D. cuwicaulis, D. gramen, D. lithophilo, D. oblongu,0. tricomis, 3. urceolata, Pontigulasia compressa, p. uhs, Euglypho scutigero, E. acanthophora, Tracheleuglypha dentate, Trinemo enchelys 등 7과 10속 24종이 동정 · 분류되었으며 , 그 중 남rcella dentate, Nebela dentistoma, 그리고 고결ugio tricomis는 한국에서는 처음으로 기록되는 종이다.

The Arcelinida (Protozoa : Sarcomatigophora : Rhizopoda ) inhabited in Sphagnum at Taekwanryng, were taxonomically investigated. Collections of Sphagnum were made from September, 1990 to June, 1991 at swamp located in Taekwanryong. As a result of the present study, 5 species in two Families were identified, which were newly recorded from Korea ; Centropyxis platystoma Penard, Quandrulella symmetrica (Wallich), Hyalosphenia nobilis Cash and Hopkinson, Nebela equicalceus (Leidy), N. penardiana Deflandre. These five species were redescribed with photographs.

The Arcellinida and Gromiida (Protozoa ; Sacromastigophora ; Rhizopoda) inhabiting the freshwater in Chngju area were systematically investigated. Collections of samples were made from September, 1988, to August, 1989 at 10 sites located in Chngju area, Korea. As a result, 19 species and one variety in five families were identified, of which 12 species and one variety were newly recorded from Korea ; Arcella gibbosa Penard, A.polypora Penard, Centropyxis ecornis (Ehrenberg), Lesquereusia modesta Rhumbler . Nebela tuberculata (Wallich), Difflugia acuminata var. inflata Penard, D. crassa Cash and Hopkinson, d.curvicaulis Penard, D. elegans Penard, D.lithophila Penard, Pontigulasia compressa (Carter), P.vas(Leidy), Euglypha scutigera Penard. The identified species were redescribed with photographs.

Testate amoebae are useful organisms when evaluating the condition of freshwater ecosystems and wetland habitats. Herein, I report on seventeen unrecorded species of testate amoebae from Korea: Arcella arenaria, A. costata, A. hemisphaerica, Centropyxis constricta, C. discoides, C. spinosa, Difflugia amphora, D. globulosa, D. longicollis, D. penardi, Heleopera rosea, Hyalosphenia subflava, Nebela militaris, N. penardiana, Netzelia wailesi, Cyphoderia ampulla, and C. trochus.

Testate amoebae are easily recognized as their characteristic shells from other protistan groups. They in which more than 1,900 species have been recorded are mixture of heterogeneous groups mainly composed of Amoebozoa and Cercozoa. In Korea, 74 species of testate amoebae have been recorded since late 1980s. Here I report a list of 12 unrecorded species of testate amoebae from Korea which were discovered during 2016-2018: Arcella crenulata Deflandre, 1928; Centropyxis cassis(Wallich, 1864); C. delicatula Penard, 1902; C. hirsuta Deflander, 1929; C. orbicularis Deflandre, 1929; C. sylvatica (Deflandre, 1929); Cyclopyxis eurystoma Deflandre, 1929; C. intermedia Kufferath, 1932; C. kahli(Deflandre, 1929); Difflugia diafana Vucetich, 1987; D. manicata Penard, 1902; Awerintzewia cyclostoma Schoutenden, 1906. As a result the fauna of testate amoebae in Korea is composed of 86 species. There are still much more species remained to be discovered in Korea. The faunal studies on testate amoebae will provide us valuable information about freshwater and soil environments.

Some Korean marine hvdroids of the families Sphaerocorynidae, Eudendriidae, Haleciidae and Lafoeidae were observed based on the external features. Thev were collected from the coasts and islands of Korea during the years 1971-1990 by the author and others. As a result12 species and subspecies are identified, of which 6 species: Sphaerocowne bedoti, Eudendrium insigne, Eudendrium cumeum, Hydrodendron gordineri, Acwptolaria confena austrolis and Crammaria obi'etinQ tuned out to be new to the Korean fauna, which are redescribed briefly. For already known species in Korean fauna, the materials examined for this work and previous rdcore given, and not examined but already known species in Korean waters the only previous records are given for definition of the hydroid taxa. So that the Korean hvdroids of four families identified so far consist of ten genera and 19 species.
