Pogonostoma (Bathypogonum) horimichioi sp. nov. is described as new to science from western Madagascar. Apart from a detailed description, illustrations in colour photographs of the habitus, diagnostic characters and habitat of the new species are introduced. A rectified differential diagnosis of the subgenus Bathypogonum Jeannel, 1946 is performed. The new species is compared to other two hitherto known taxa of the subgenus Bathypogonum (in its narrow original concept and sensu Moravec 2007), which are P. (B.) levigatum levigatum W. Horn, 1908 and P. (B.) levigatum lucens Rivalier, 1970. Differential diagnoses of the two taxa with illustrations of their habitus and important distinguishing characters in colour photographs are presented. References to their detailed redescriptions and illustrations, as well as to those of the subgenera Neopogonum Moravec, 2007 and Parapogonum Moravec, 2007 in the monograph of the genus Pogonostoma by Moravec (2007) are given. Essential maps of distribution are also presented.
本文描述了来自马达加斯加西部的一种新的巴氏短须魮属（Bathypogonum）鱼类，即波氏短须魮（Pogonostoma horimichioi sp. nov.）。除了详细的描述外，本文还介绍了新物种的生境、外部形态和鉴别特征的彩色照片插图。对巴氏短须魮属（Bathypogonum Jeannel, 1946）进行了修正的鉴别诊断。将新种与巴氏短须魮属（Bathypogonum）中迄今已知的另外两个分类群（狭义原始概念和 Moravec 2007 中的概念）进行了比较，即巴氏短须魮指名亚种（P. (B.) levigatum levigatum W. Horn, 1908）和巴氏短须魮光亮亚种（P. (B.) levigatum lucens Rivalier, 1970）。本文对这两个分类群进行了鉴别诊断，并附有它们外部形态的插图和彩色照片中的重要鉴别特征。此外，还给出了巴氏短须魮属（Bathypogonum）和新短须魮属（Neopogonum Moravec, 2007）以及拟短须魮属（Parapogonum Moravec, 2007）在 Moravec（2007）的《短须魮属》专著中的详细重述和插图的参考文献。还提供了关键的分布地图。
