Abstract Gymnoichthys inopinatus was initially described by Tintori et al. in 2010, and regarded as a basal neopterygian. According to the new material of the Guanling Formation discovered in Dawazi Village, Luoping County, Yunnan Province, China, we redescribed G. inopinatus, and re-identified its systematic position. G. inopinatus has only one supramaxilla and its symplectic is likely jointed with the articular, which are the identifying characters of . Morever, G. inopinatus has no scales, its vertebral centra are not ossified, and the structure and relationship of the neural arches and neural spines, as well as the shape of teeth and ural haemal spines in G. inopinatus are quite like that of the caturoids. Hence, it is suggested to consider G. inopinatus as a basal form of the superfamily Caturoidea. Previously, caturoids were only discovered in the of Europe and North America, and its recognized forms included Liodesmus, the only genera of the family Liodesmidae, and and Amblysemius of the family . Gymnoichthys inopinatus is not only the first caturoid found in China, but also the earliest caturoid in the world, which is 40 million years earlier than the European and North American caturoids.
