摘要
借助活体观察和蛋白银染色方法对采集于中国山东、广东沿海的潮间带、红树林及淡水生境的10种旋唇纲纤毛虫(拉氏伪小双虫Pseudoamphisiella lacazei、四核伪小双虫Pseudoamphisiella quadrinucleata、中华偏全列虫Apoholosticha sinica、维尔伯特泡毛虫Tunicothrix wilberti、海洋后尾柱虫Metaurostylopsis marina、偏澳大利亚速体虫Notohymena apoaustralis、偏寡毛双眉虫Diophrys apoligothrix、寡毛双眉虫Diophrys oligothrix、盾圆双眉虫Diophrys scutum、张氏拟双眉虫Paradiophrys zhangi)进行了活体形态与纤毛图式水平的分类学研究。其中偏澳大利亚速体虫、偏寡毛双眉虫、张氏拟双眉虫为广东地区新记录种。基于新种群,对张氏拟双眉虫给出了新定义。研究表明,中华偏全列虫地理分布较广,可适应从淡水到不同盐度的咸水生境。首次发现,寡毛双眉虫可在盐度较低的咸水中生存,显示出其较强的环境适应能力。
Ten species of spirotrichean ciliates,i.e.,Pseudoamphisiella lacazei,P.quadrinucleata,Apoholosticha sinica,Tunicothrix wilberti,Metaurostylopsis marina,Notohymena apoaustralis,Diophrys apoligothrix,D.oligothrix,D.scutumand Paradiophrys zhangi,collected from intertidal zone,mangroves and freshwater habitats of Shandong andGuangdong,China,were morphologically investigated with live observation and protargol staining methods.Morphologicaldescriptions and morphometric data were provided.The current research revealed that N.apoaustralis,D.apoligothrixand P.zhangi were first recorded in Guangdong province.Based on the new data,P.zhangi was redefined asbelow:body ca.(70-110)μm×(40-60)μm in vivo,rectangular,with sculptured surface;adoral zone bipartite,composedof26-34membranelles;endoral membrane reduced or absent;mostly four transverse and two ventral cirri,fiveor six frontal cirri;consistently three left marginal and three caudal cirri,six dorsal kineties,and two globular macronuclearnodules.A.sinica can survive under environments with different salinity,which suggests that it may have awide geographical distribution.For the first time D.oligothrix was found having strong ability to adapt to the environment.
