摘要 对目前已发表下毛目纤毛虫的200个属级阶元进行了重新修订。给出新修订的下毛目系统,并根据其纤毛图式和形态发生特点将其归为5亚目20科82属。原下毛亚目Protohypotrichinasubordernov.,翁柯虫科Onychodromusidaefam.nov.,腹柱虫科Gastrostylidaefam.nov.和拟角毛虫属Parakeronopsisgen.nov.为新设,给出了下毛目中各亚目和科的特征简述及亚目及科的检索表。各属的特征以特征简述、检索表以及属的模式图的形式介绍之。新立原下毛亚目Protohypotrichinasubordernov.,并对排毛亚目Stichotrichina中的科属进行了重新修订。原下毛亚目的特征为无明确缘棘毛分化;排毛亚目的特征为无明确额-腹-横棘毛分化,腹棘毛为长的纵列,数目多,形式多样。修订后的原下毛亚目含2科3属,排毛亚目含5科29属。各科的基本特征分别为:原毛虫科Phacodinidae无明确体棘毛和背触毛的分化;凯毛虫科Kitrichidae体纤毛器背腹有明确分化,有原始的背触毛分化;旋毛虫科Spirofilidae腹棘毛旋列或斜向排列;卡尔虫科K? In the present study, 200 reported genera and parts of the families were re analyzised and compared in the present study. The authors re arranged the 200 genera comprehensivelly, holding that 82 of the cilia patterns were confirmed, on which most of the genera were support by the work of morphogenesis. Therefore they are stipulated as the confirmed genera in this thesis. The cilia patterns by silver staining techniques were also shown respectively. According to the cilia patterns and the features of morphogenesis, the authors grouped all the categories in hypotrichida into 5 suborders, 20 families and 82 genera, among which the Protohypotrichina suborder nov., Onychodromusidae fam. nov., Gastrostylidae fam. nov. and Parakeronopsis gen. nov. were erected. A new revised system of Hypotrichida, the key to genera (family) of Hypotrichida were also been provided. The order, suborder and family were briefly described and the key to suborder, families and genera as well as the cilia patterns were provided. The Systematic Revision of Order Hypotrichida was composed of three parts, namely Part Ⅰ. Protohypotrichina and Stichotrichina, Part Ⅱ. Urostylina and Part Ⅲ. Sporadotrichina and Euplotina. Here is the Part Ⅰ. Part II and Ⅲ will be continued in the coming number of the Journal. In the present study, the authors re arranged the categories of Protohypotrichina suborder nov. and Stichotrichina Fauré Fremiet (family, genera). The Protohypotrichina suborder nov. was composed of 3 genera, 2 families and the revised Stichotrichina, 29 genera, 5 families. The characteristic of all the families in Protohypotrichina suborder nov. ware: the marginal cirri of no obvious differentiation. The characteristic of all the families in Stichotrichina was: the frotal cirri and transverse cirri without differentiated, but there were the long longitudinal ventral cirri, which are numerous and of various types. The basic character in each families are: Phacodinidae, without differentiated somatic cirri and dorsal kineties. Kiitrichidae, the somatic ciliature had obviously differentiated both ventrally and dorsally, there were primitively differentiated dorsal kineties. Spirofilidae, the ventral cirri rows distribute obliquely. Kahliellidae, with more than one row of marginal cirri in both left and right side. Amphisiellidae, with only one row of ventral cirri. Keronopsidae, with two or more rows of ventral cirri. Onychodromusidae, somatic cirri began to differentiate front cirri, ventral cirri and transverse cirri. The brief statements of the characters of the suborder, family and genera were given and their key to families were provided as well. The authors introduced the character of each genera by a brief statement and the key to genera as well as the cilia patterns figures of the genera. In the genera that had various types, we also gave more than one cilia patterns figures besides the typical cilia patterns figure of the genera.
