十种海洋寡毛类纤毛虫:形态学及分类学修订

利用活体观察和蛋白银染色技术对近年来采自青岛、大亚湾、湛江沿岸水体的10个海洋寡毛类纤毛虫种:侧扁急游虫Strombidium apolatum Wilbert & Song,2005、具头急游虫Strombidium capitatum (Leegaard,1995) Kahl,1932、广东急游虫Strombidium guangdongense Liu,et al.,2016、拟卡氏急游虫Strombidiumparacalkinsi (Lei,et al.,1999) Agatha,2004、拟楔尾急游虫Strombidium parastylifer Song,et al.,2009、铃木急游虫Strombidium suzukii Song,et al.,2009、束腰旋游虫Spirostrombidium cinctum (Kahl,1932) Petz,et al.,1995、杨科夫平游虫Parallelostrombidium jankowski (Song,et al.,2009) Song,et al.,2018、卡尔平游虫Parallelostrombidium kahli (Song,et al.,2009) Song,et al.,2018、最小拟盗虫Strombidinopsis minima (Gruber,1884) Song & Bradbury,1998的形态学开展了比较研究,补充和厘定了有关形态特征、纤毛图式以及性状变异等分类学新信息。

TAXONOMY STUDIES ON TEN MARINE OLIGOTRICH CILIATES (PROTOZOA,CILIOPHORA)

The oligotrich ciliates are important components of the marine microplankton. Many studies have been carried out on the taxonomy of these taxa in the past one and a half centuries. However, ambiguities concerning their identification have been accumulated due to lacking key morphological characters. Ten poorly known oligotrichs, Strombi-dium apolatum Wilbert & Song, 2005, Strombidium capitatum (Leegaard, 1995) Kahl, 1932, Strombidium guangdongense Liu, et al., 2016, Strombidium paracalkinsi (Lei, et al., 1999) Agatha, 2004, Strombidium parastylifer Song, et al., 2009, Strombidium suzukii Song, et al., 2009, Spirostrombidium cinctum (Kahl, 1932) Petz, et al., 1995, Paralle-lostrombidium jankowski (Song, et al., 2009) Song, et al., 2018, Parallelostrombidium kahli (Song, et al., 2009) Song, et al., 2018, Strombidinopsis minima (Gruber, 1884) Song & Bradbury, 1998 were investigated using live observation and protargol impregnation methods. Based on the present populations, much more information particularly with respect to their morphological features in vivo as well as original morphometric data were provided. Compared with previous population, some variable characters of these species were recorded.
