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]

Description

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]
