Abstract

The article focuses on the discovery and description of *Diandongichthys ocellatus* gen. et sp. nov., a new basal ginglymodian fish from the Early-Middle Triassic (Anisian) marine deposits of Luoping, eastern Yunnan, China. Based on 13 well-preserved specimens, this small-sized species (maximum standard length 41 mm) exhibits a combination of primitive and derived features that place it at the base of the Ginglymodi clade, distinct from other early ginglymodians such as kyphosichthyiforms and *Ticinolepis*. The study’s phylogenetic analysis supports the monophyly of Holostei (including Ginglymodi and Halecomorphi) and highlights *Diandongichthys* as one of the oldest known ginglymodians, providing new insights into the origin and early diversification of this group of holostean fishes.
