摘要
作为系列报道的第二部分记述了黄渤海区共栖于对虾体表的3属15种缘毛类纤毛虫,其中包括8种国内新记录及聚缩虫属的一新种——拟钩虾聚缩虫。文中对所涉种类的形态学特征做了概括性描述及图示,以期为对虾养殖中病原的调查鉴定及进一步的动物区系研究提供一基础资料。
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
