摘要： 报告了寡毛双眉虫(Diophrys. oligothrix) 的形态学特征以及它在无性分裂时期形态发生的全过程。观察了前仔虫口围带的形成过程，并将其与亲代的口围带进行比较，认为前仔虫口围带是经过重建的。从口器、大核等的情况反映出寡毛双眉虫与游仆虫、盾纤虫以及尾刺虫在进化上的关系。并认为前、后仔虫形成后仍继续恢复其典型的纤毛模式。

Abstract: The morphology, morphogenesis of Diophrys oligothrix during the asexual division were studied in detail. Studying on the development of adoral zone of membranelles(AZM) and comparing the AZM of daughters with its parental AZM, we conclude that the AZM of the proter is reorganized. Comparing the
morphogenesis of macronuclei and the nuclear apparatus among D. oligothrix, Euplotes and Aspidisca, we can find evolutionary relation among them. After binary division, both the proter and the opisthe of D. oligothrix still recover their ciliary pattern.

Key words: morphology, morphogenesis, AZM (adoral zone of membranelles), Diophrys oligothrix, morphology, morphogenesis, AZM (adoral zone of membranelles)
