Bibarba bibarba is a species of loach that is found in the Chengjiang River of the Long River system in China. [1] It is the only known congener of Bibarba parvoculus, a troglobitic species described in 2015, from which it is believed to have evolutionarily split in the Early Miocene. [2] [3]
B. bibarba is a surface-dwelling species with normal eyes. [3] Males display a duplication of the lamina circularis on the second and third pectoral rays. The coracoid, mesocoracoid, and scapula are stouter in males, and the three bones are fused with the cleithrum. [3] It differs from B. parvoculus, by having lower vertebral counts, a narrower anterior part of the frontal bone at the orbital region, and increased sexual dimorphism. [3]
