The morphology and infraciliature of the new hypotrichous ciliate, sp. nov., and a Chinese population of Blatterer & Foissner, 1988, are investigated using live observation and protargol staining. sp. nov. is defined by the body size 85-130 µm × 30-50 µm in vivo, the typical oxytrichid 18 frontoventral-transverse cirri, cortical granules absent, undulating membranes reduced or absent, three caudal cirri, dorsal kineties in pattern, and two ellipsoidal macronuclear nodules. The Chinese population of differs slightly from other populations in the arrangement and color of cortical granules and position of anterior end of dorsal kinety 4. Phylogenetic analyses based on SSU-rDNA sequences support the assertion that belongs to and Oxytrichidae.
利用活体观察和蛋白银染色法,对新的下毛目纤毛虫物种(新物种)以及1988年布拉特勒和福斯纳报道的中国种群的形态和纤毛下器进行了研究。新物种的活体大小为85 - 130微米×30 - 50微米,具有典型的尖毛科18条额腹横棘毛,无皮层颗粒,波动膜减少或无,三条尾棘毛,背纤毛列呈特定模式,以及两个椭圆形大核结节。中国种群在皮层颗粒的排列和颜色以及背纤毛列4前端的位置上与其他种群略有不同。基于小亚基核糖体DNA(SSU - rDNA)序列的系统发育分析支持了该物种属于尖毛科的论断。
