A new Euplotes species, isolated from abyssal depths (>4000 m) of the North Atlantic Ocean, was described based on morphology, ciliary pattern and molecular data. Euplotes dominicanus sp. n. is characterized by a small body size (29–40 × 17–27 μm in vivo), 18–22 adoral membranelles, 10 frontoventral, five transverse and two left marginal cirri and one caudal cirrus, five or six dorsolateral kineties with 7–9 dikinetids in mid-dorsolateral kinety (DK3), and dorsal silverline system of the double-eurystomus type. Phylogenetic analyses inferred from 18S rRNA sequences show that Euplotes dominicanus sp. n. is most closely related to E. curdsi, with a sequence similarity of 97.6 %. Euplotes dominicanus sp. n. was able to survive hydrostatic pressures up to 500 bar indicating its barotolerance. Metabarcoding data demonstrate the presence of E. dominicanus sp. n. in sediments of several deep-sea basins.

根据形态，纤毛模式和分子数据，描述了一种新的Euplotes物种，它是从北大西洋的深渊（> 4000 m）中分离出来的。真核多米尼加sp。。其特点是体形小（体内29–40×17–27μm），18–22个动脉膜，10个额腹，5个横向和2个左边缘卷毛，1个尾侧卷毛，5个或6个背外侧运动以及7–9个背中外侧肌腱（DK3）的双侧突肌以及双eurystomus类型的背侧银线系统。从18S rRNA序列推断的系统发育分析表明，Euplotes dominicanus sp。。与E. curdsi关系最密切，序列相似性为97.6％。真核多米尼加sp。。能够承受高达500 bar的静水压力，表明其耐压性。元条形码数据证明了多米尼加大肠杆菌的存在。。在几个深海盆地的沉积物中。
