Chaohuperleidus primus has yet to be completely described due to the limit of the original material which were collected from Upper Member of the Nanlinghu Formation (Spathian, Olenekian, Early Triassic) at Majiashan quarry, Chaohu City, Anhui Province. The taxon was redescribed in detail by adding three complete specimens from the type horizons. The generic diagnosis of Chaohuperleidus was revised mainly based on newly recognized anatomical information, of which the following characters ‘the fused parietal and dermopterotic with anterior, middle and posterior pit-lines; the operculum and suboperculum of nearly equal in height with the latter having a large rounded anterior dorsal process’ were possible apomorphies of Chaohuperleidus. The previous taxonomic assignment of the Chaohuperleidus was confirmed, which was similar to the Ladinian (Middle Triassic) genus Perleidus but differed the latter in having more suborbitals, branchiostegal rays and epaxial fin rays besides its possible apomorphies. The skull pattern of the Chaohuperleridus primus was exhaustively reconstructed and was anatomically compared with the Early Triassic taxa which were wrongly classified into the Perleidiformes and some newly described stem neopterygians. The result herein will provide new anatomical evidences for the phylogeny analysis of the stem neopterygians that is open to discuss.
