Notes on Gregarines in Japan 4 : Two Eugregarines from Tricoptera larvae

Creators Hoshide Kazumi

The author has been studied upon the gregarines fauna in Japan since 1967 and recorded some gregarines from terrestorial and aquatic insects (1968, 1969). He wants to report the morphorogical and taxonomical descriptions of two new Eugregarines from Tricoptera larvae in this paper. Many species of Tricoptera larvae were reported by lwata or Tsuda (1962) in Japan, but only one gregarine which is parasite of Tricoptera larva was reported by Hyoma Hoshide (1953). He reported that this species belongs to Pileccephalus, but according to the Baudoin's conception(1967) it should be attached to the other genus Asterophora. Recently the author observed three Tricoptera larvae around Yamaguchi City and found two new gregarines from them. The existence of Gemmicephalus japonicusn. Sp. Was already related by Hyoma Hoshide, but there is no description yet. At that time H. Hoshide thought this species belonged to the genus Poleocephalus but the author thinks it should be attached to the genus Gemmicephalus. This observation was done from March to June in 1972.
