Ciliates of the genus Gruberia are poorly studied. Consequently, most species lack detailed morphological descriptions, and all gene sequences in GenBank are not classified at the species level. In this study, a detailed morphological description of a population of G. lanceolata from Brazil is presented, based on live and protargol-stained organisms. We also present the 18S rRNA gene sequence and the phylogenetic position of this species. The primary characteristics of G. lanceolata from the Maricá Lagoon are as follows: an elongate fusiform body 280-870 × 40-160 μm in size; rosy cortical granules; a peristome occupying approximately 1/3-1/2 of body length; an adoral zone comprising 115-330 membranelles; a paroral membrane in 35-50 fragments; and a moniliform macronucleus with 11-16 nodules. Based on our observations and data from pertinent literature, we suggest G. beninensis to be a junior synonym of G. lanceolata.
格鲁贝属纤毛虫的研究较少。因此，大多数物种缺乏详细的形态学描述，而且GenBank中的所有基因序列都未在物种水平上进行分类。在本研究中，基于活体和经原银染色的生物体，对来自巴西的一群披针格鲁贝虫进行了详细的形态学描述。我们还给出了该物种的18S rRNA基因序列及其系统发育位置。来自马里卡泻湖的披针格鲁贝虫的主要特征如下：身体细长呈梭形，大小为280 - 870×40 - 160μm；皮层颗粒呈玫瑰色；口围约占体长的1/3 - 1/2；口围带由115 - 330片小膜组成；口侧膜分成35 - 50个片段；念珠状大核有11 - 16个结节。基于我们的观察以及相关文献的数据，我们认为贝宁格鲁贝虫是披针格鲁贝虫的次异名。
