Abstract

A taxonomic study on the marine sponges was conducted with materials which were collected from Ulleung Island and Chuja Island, Korea by SCUBA diving during the period of July 2000 to May 2005. Among them, two species, Mycale (Aegogropila) jukdoensis n. sp. and Mycale (Mycale) chujaensis n. sp. are new to science. M. (A.) jukdoensis n. sp. seems closely to M. grandis based on the shape of spicules, but our new species has two categories of subtylostyles and also larger sigmas and raphides than those of M. grandis. And anisochelae I of M. (A.) jukdoensis n. sp. is smaller than that of M. grandis. M. (M.) chujaensis n. sp. is similar to M. sulgata in the growth form and size of microscleres. However, the new species has two categories of subtylostyles instead of one type in M. sulgata.

2000년 7월부터 2005년 5월까지 울릉도와 추자도에서 SCUBA 다이빙으로 채집된 해면동물을 동정$\cdot$분류한 결과 깃해면속(Mycale)의 2종 죽도깃해면[Mycale (Aegogropila) jukdoensis n. sp.]과 추자깃해면[Mycale (Mycale) chujaensis n. sp.)이 신종으로 밝혀졌다. 죽도깃해면은 M. grandis와 골편의 구성에서는 유사하지만 시그마체와 라피드가 M. grandis의 것보다 크고, 두 종류의 준아령침상체를 가진다. 또한 죽도깃해면의 이조상체 I은 M. grandis의 것보다 작다. 추자깃해면은 M. sulgata와 성장형태와 미소골편의 크기가 매우 유사하지만, 추자깃해면은 두 종류의 준아령침상체를 갖는 대신 M. sulgata는 단지 한 종류를 갖는다.
