TABLE 5. Summary statistics reported by the species delimitation plugin for mtDNA COI gene in each putative species using pairwise interspecific genetic distances between Serranus species (distances between S. cabrilla, S. knysnaensis and S. novemcinctus are highlighted in bold). The barcoding gap analysis results for two relative interspecific gap widths (X; 1.5 and 2.0) using the ABGD test are also indicated.

	Species	Nearest Neighbour	Intra- specific	Inter- specific	Intra/ Inter	P ID(Strict)	P (Randomly Distinct)	P AB	X=1.5 P= 0.0046	X=2.0 P= 0.0129
NOTE: Intra/Inter is the ratio of intraspecific to interspecific pairwise distances and provides a measure of genetic differentiation between closest species; P ID(Strict) is the average probabillity (95% confidence interval) of correctly identifying members of a given cluster using the placement in the tree; Rosenberg’s P AB is the probability of a species being reciprocally monophyletic under a random coalescent model; P(Randomly Distinct) is the probability that a cluster has the observed degree of distinctiveness due to random coalescent processes.
