本文报道了一种新的淡水膜口虫科纤毛虫--哈氏前青光眼的形态、纤毛下结构和SSU rDNA序列。十一月，spec. nov.，从中国哈尔滨的一个农田池塘中收集的，进行了调查。新属Anteglaucomais的特征如下：小至中型的Glaucomidae，口器位于细胞的前三分之一;口旁膜由几乎纵向排列的双动子组成;三个口旁膜几乎等长，几乎纵向平行排列;银线图案四膜虫。本文在前人工作的基础上，对海虱科的诊断方法进行了改进。模式种Anteglaucoma harbinensis spec. nov.具有32-35个体动子; 4或5个口后动子;膜1和膜2具有5或6个动子排，膜3具有3个动子排;单个大核结节;收缩泡平均位于体后端的15%;运动特征为爬行，具有相当忙碌的抽搐运动;淡水栖息地。系统发育分析表明，Anteglaucoma可分为Glaucomidae科和Glaucoma属。分子生物学和形态学数据表明，在系统发育树中，海虱科与雀麦科亲缘关系最近。
The morphology, infraciliature and SSU rDNA sequence of a new freshwater hymenostomatid ciliate,Anteglaucoma harbinensisgen. nov., spec. nov., collected from a farmland pond in Harbin, China, were investigated. The new genusAnteglaucomais characterized as follows: small to medium‐sized Glaucomidae with oral apparatus in anterior one‐third of cell; paroral membrane composed of almost longitudinally arranged dikinetids; three adoral membranelles nearly equal in length and arranged almost longitudinally in parallel; silverline pattern tetrahymenid. The improved diagnosis of family Glaucomidae Corliss 1971 is provided based on the previous and present work. The type speciesAnteglaucoma harbinensisspec. nov. is defined by having 32–35 somatic kineties; four or five postoral kineties; membranelle 1 and membranelle 2 having five or six kinetosomal rows, membranelle 3 having three kinetosomal rows; single macronuclear nodule; contractile vacuole on average 15% from posterior body end; locomotion characterized by crawling with a rather hectic jerking motion; freshwater habitat. Phylogenetic analyses show thatAnteglaucomaclusters in the family Glaucomidae and groups with the generaGlaucoma. The molecular and morphological data indicate that Glaucomidae is related to the family Bromeliophryidae in the phylogenetic trees.
