species are typical cave-dwelling fish, exhibiting distinctive morphological adaptations such as colorless body, lack of eyes, and reduced scales and ribs in response to their extreme cave habitats. Distinct from the recorded species, , , and , a new species, sp. nov., is described from Guangxi Zhuang Autonomous Region, China. sp. nov. can easily be distinguished from all known congeners by the following characteristics: whole body covered by scales except head, 12 branched caudal fin rays, and long ribs. These species face threats from habitat degradation, hydrological changes, and environmental pollution. Thus, the conservation of cavefish in China has become an urgent issue.
这些物种是典型的洞穴栖息鱼类,表现出独特的形态适应,如无色身体、缺乏眼睛以及减少鳞片和肋骨,以适应其极端的洞穴栖息地。与已记录的物种不同,来自中国广西壮族自治区的一个新物种, sp. nov. 被描述。 sp. nov. 可以通过以下特征与所有已知的近缘种轻易区分:全身除头部外均有鳞片,12 根分支的尾鳍鳍条,以及长肋骨。这些物种面临着栖息地退化、水文变化和环境污染的威胁。因此,中国洞穴鱼类的保护已成为一个紧迫的问题。
