Catopra tetracanthus Gunther 1862

Catopra tetracanthus Günther 1862: a junior synonym of Pristolepis marginata Meristic data available in the original description of Catopra tetracanthus, along with the data provided by Britz et al. (2012), closely match those in Jerdon’s (1849) description of P. marginata (Table. 1). The range in fin-ray counts of P. marginata observed in the present study is also consistent with those reported by Jerdon (1849), except for the occasional presence of five anal-fin spines, which was unknown to Jerdon (1849). When larger sample sizes of P. marginata are considered, significant variation is evident in the number of dorsal-fin rays (11–12), anal-fin rays (7–8), and anal-fin spines (4–5) (Fig. 6). New data on meristics of both the species reveal they are conspecific, and that Catopra tetracanthus Günther, 1862 is a junior synonym of Pristolepis marginatus [sic] Jerdon, 1849.
