Originally named Sinosaurichthys by Wu et al., 2011, the genus was reranked as Saurichthys by A. Tintori (2013)
Diagnosis from Wu et al. 2011, p. 595: "Medium−sized Sinosaurichthys (standard body length ranging from 270–470 mm) with unusually elongated median fins with relatively few segments of fin rays; less number of neural arches between opercle and caudal fin (approximately 157–172), less number of anterior ones with neural spines (130–146); and less number of mid−dorsal scales in front of dorsal fin (69–86) than in type species; 14–15 distinct haemal spines in caudal region; pectoral fin triangular shaped with length about 1/3 of mandible length (shared with S. minuta described below); posttemporal−supracleithrum from either side separated from each other by anterior mid−dorsal scales (shared with S. minuta described below); cleithrum plate (depth/length ratio ca. 1.2–1.25) much lower than in type species (approximately 1.8), but close to that in S. minuta (ap− proximately 1). Fin formula: P 18–19, V 18–20, D/A 44–49/ >40–48, C 37–39/37–39."
