摘要

在重庆发现了一种新的次色纤毛虫，Oxytrichachongqingica sp. nov.。该物种通过各种定性和定量特征与同类区分，如身体大小和形状，口内和口旁的模式，大核结节的数量，皮质颗粒的存在和排列，以及腹侧和背侧纤毛。基于小亚基核核体DNA （SSU rDNA）序列的系统发育分析表明，Oxytrichachongqingica sp. 11与O.nauplia、Allotrichidesantarcticus、o.p arranulifera、o.k quadricirrata、Paroxytrichalongigranulosa和p.o tttowi形成一个集群，尽管节点支持较弱或中等（82 ML和0.87 BI）。

Morphology of a novel ciliate, Oxytrichachongqingica sp. nov. (Ciliophora, Hypotrichia).

A novel hypotrichous ciliate, Oxytrichachongqingica sp. nov., was identified in Chongqing, southwestern China. This species is distinguishable from congeners by various qualitative and quantitative characteristics, such as body size and shape, pattern of endoral and paroral, number of macronuclear nodules, presence and arrangement of cortical granules, as well as ventral and dorsal ciliature. Phylogenetic analyses based on small subunit ribosomal DNA (SSU rDNA) sequences indicate that Oxytrichachongqingica sp. nov. forms a cluster with O.nauplia, Allotrichidesantarcticus, O.paragranulifera, O.quadricirrata, Paroxytrichalongigranulosa, and P.ottowi, albeit with weak or moderate nodal support (82 ML and 0.87 BI).
