It is widely accepted among the Cladocera (Crustacea) taxonomists that almost all cosmopolitan taxa are represented by some un-revised complexes of cryptic species. But many macro taxa of the cladocerans are still unrevised. The aim of this work is to analyze the taxonomic status of Oriental populations of the genus Bosminopsis Richard, 1895 (Anomopoda: Bosminidae) based on morphological characters. We have studied populations from India, Myanmar, Cambodia, Thailand, Laos, Vietnam, Philippines, Malaysia and Papua New Guinea and concluded that Oriental populations belong to a single species, Bosminopsis africanus (Daday, 1908), initially described from Africa. Analysis of literature data confirms that is widely distributed through whole Oriental zone. A single large mucro, or the mucro accompanied by an additional small spine in both sexes, is the main trait which differentiates B. africanus from B. zernowi Linko, 1901 distributed in more northern regions of Eurasia.
在枝角类（甲壳纲）分类学家中，几乎所有世界性的分类单元都被认为是由一些未修订的隐种复合体代表的，这一观点得到了广泛认可。但是，许多枝角类的大型分类单元仍未被修订。本研究的目的是基于形态特征分析东方地区的波氏真象鼻溞属（弯额溞科）的分类地位。我们研究了来自印度、缅甸、柬埔寨、泰国、老挝、越南、菲律宾、马来西亚和巴布亚新几内亚的种群，得出结论认为东方地区的种群属于单一物种，即非洲真象鼻溞（Daday，1908），最初是在非洲描述的。文献数据分析证实，它广泛分布于整个东方区。两性个体的单一大型刚毛，或刚毛伴有一个额外的小刺，是将非洲真象鼻溞与分布在欧亚大陆更北部地区的 B. zernowi Linko，1901 区分开来的主要特征。
