摘要
采用现代通行的蛋白银染色法及Foissner干银法对共栖在对虾体表的钟虫属11种致病性纤毛虫做了形态分类学研究。报道了5种国内新记录。对所涉种类的银线系及纤毛下器做了首次揭示与描述,并列表对诸种的分类特征进行了统计学界定。
This paper is a continuation of the studies dealing with some disease-ausing,commensal peritrich ciliates on the penaeid shrimp Penaeus orientalis found in the Bohai Bay and the Yellow Sea.15 species are reported biometrically,of which a new species is described :Zoothamnium paragammari nov.spec.(Fig.1a-e,Tab.1)Type location,marine water,Wendeng,Shandong ProvinceType specimens.College of Fisheries,Ocean University of Qingdao- Diagnosis:Body widest at the anterior 1/3 with the relative thick,one layer peristo-mial border,body tapering posteriorly.Pellicle smooth,endoplasm hyaline and colorless.Contractile vacuole apically located: macronudeus C-shaped.Stalk thick,somewhat pleated;colony small,dichotomously branched.Remarks.This animal differs from Z.gammari Dietz,1964 in the body shape and the stalk: the latter is elongate-oval with the striated stalk.Because the name Zoothamnium truncatum SONG,1986 is a junior primary homonym,a new name,Z.sinensis nom.nov.,would be given here.The Z.cupiforum SONG,1986 (sphalm.typogr.) will be also corrected Z.cupiferum
