The oxytrichid ciliate Architricha indica nov. gen., nov. sp., isolated from the river Yamuna, Delhi, shows a new combination of characters. It possesses a flexible body, 18 frontal-ventral-transverse (FVT) cirri, 3 right and 2 left marginal cirral rows, 6 dorsal bristle rows and 3 caudal cirri (CC). The FVT cirri arise from 6 primordia, which utilize 6 parental cirri in their origin as is typical of Oxytricha species. Multiple marginal rows (MMR) develop through 5 independent marginal primordia arising "within-row", 1 in each parental marginal row. All the 5 marginal rows are thus morphogenetically active. Such a mode of formation of MMR has not been recorded among oxytrichids and has necessitated separation of A. indica at the generic level. Histriculus, on the other hand, has well-known characteristics, viz. rigid body, confluent marginal rows and absence of CC. The morphogenesis of Histriculus histrio has been described by Berger and Foissner [1997. Cladistic relationships and generic characterization of oxytrichid hypotrichs (Protozoa, Ciliophora). Arch. Protistenkd. 148, 125-155]. Reinvestigation of very early stages of development revealed that (i) the FVT cirral primordia utilize kinetosomes from 5 parental FVT cirri, (ii) the primordium II of the proter is of a composite origin: kinetosomes from the oral primordium merge with the primordium II that originates from the buccal cirrus II/2 and (iii) the FVT primordia V and VI for the 2 daughter cells arise sequentially from the parental cirrus V/4. Thus, the genus Histriculus exhibits a new combination of characters with respect to the origin of FVT cirri, an additional pattern to be added to the known 6 patterns of FVT development in oxytrichids [Berger and Foissner, 1997; Berger, H., 1999.

从德里亚穆纳河分离出的尖毛虫纲纤毛虫印度新列毛虫属（Architricha indica），新属，新种，展现出了一系列新的特征组合。它具有灵活的身体，18条额腹横纤毛（FVT），3排右侧边缘纤毛和2排左侧边缘纤毛，6排背刚毛以及3条尾纤毛（CC）。FVT纤毛起源于6个原基，在其起源过程中利用了6条亲代纤毛，这是尖毛虫属物种的典型特征。多排边缘纤毛（MMR）通过5个独立的边缘原基发育形成，这些原基在亲代的每一排边缘纤毛内“排内”产生。因此，所有5排边缘纤毛在形态发生上都是活跃的。这种MMR的形成方式在尖毛虫中尚未有记录，因此有必要在属的层面上对印度新列毛虫进行区分。另一方面，Histriculus具有众所周知的特征，即身体坚硬、边缘纤毛融合且没有尾纤毛。Berger和Foissner [1997年。尖毛虫亚目（原生动物，纤毛虫纲）的分支关系和属的特征描述。原生动物学文献148，125 -
155] 描述了Histriculus histrio的形态发生过程。对其发育早期阶段的重新研究表明：（i）FVT纤毛原基利用了5条亲代FVT纤毛的动基体；（ii）前仔虫的原基II具有复合起源：来自口原基的动基体与起源于颊纤毛II/2的原基II融合；（iii）两个子细胞的FVT原基V和VI依次来自亲代纤毛V/4。因此，Histriculus属在FVT纤毛的起源方面展现出了一种新的特征组合，这是要添加到尖毛虫中已知的6种FVT发育模式中的另一种模式 [Berger和Foissner，1997年；Berger，H.，1999年。尖毛虫科（纤毛虫纲，下毛目）专论，Kluwer学术出版社，多德雷赫特/波士顿/伦敦]。
