最近的研究表明，“低等”海洋纤毛虫的多样性远远超过以前的怀疑。在对青岛北方纤毛虫区系的调查中，我们分离到了30个新的或鲜为人知的种类。本文研究了两种鞘翅目昆虫，东方诺兰地亚（Nolandia orientalis spec. nov.）和相似平腹鞘翅目（Pinacocoleps similis（Kahl，1933）comb. nov.）根据活体观察和银沉积记录了它们的形态和下纤毛结构。新种Nolandia orientalis与模式种N.诺兰迪主要是在结构层板。层板的结构也是将Coleps similis Kahl，1933转移到Pinacocoleps属和另外三个新组合的基础：Pinacocoleps heteracanthus（Noland，1937）comb. nov.（基本名称：异刺囊线虫（Coleps heteracanthus Noland，1937）、螺旋囊线虫（P spiralis（Noland，1937）comb. nov.（basionym：Coleps spiralis Noland，1937）和Pinacocoleps arenarius（Bock，1952）comb. nov.（basionym：Coleps arenarius Bock，1952）。(C)2010年Elsevier GmbH。All rights reserved.
Recent studies have revealed that the "lower" marine ciliates are far more diverse than previously suspected. During a survey on the ciliate fauna in coastal waters of Qingdao, northern China, we have isolated about 30 new or poorly known taxa. In the present study two colepid species are investigated, Nolandia orientalis spec. nov. and Pinacocoleps similis (Kahl, 1933) comb. nov. (basionym: Coleps similis Kahl, 1933). Their morphology and infraciliature are documented based on living observations and silver impregnations. The new species Nolandia orientalis differs from the type species N. nolandi mainly in the structure of tier plates. The structure of the tier plates was also the basis for transferring Coleps similis Kahl, 1933 to the genus Pinacocoleps and for three further new combinations: Pinacocoleps heteracanthus (Noland, 1937) comb. nov. (basionym: Coleps heteracanthus Noland, 1937), P spiralis (Noland, 1937) comb. nov. (basionym Coleps spiralis Noland, 1937) and Pinacocoleps arenarius (Bock, 1952) comb. nov. (basionym: Coleps arenarius Bock, 1952). (C) 2010 Elsevier GmbH. All rights reserved.
