One species was assessed, namely Rhynchobatus djiddensis , and it formed two distinct sub-clusters ( Fig. 2 View Figure 2 ). Their between-group mean distance was 3.87 ± 0.81%. Although this species was not assessed by Naylor et al. (2012), congeners from that study separated the R. djiddensis sub-clusters when all were viewed together ( Fig. 10 View Figure 10 ). Considerable variation in pattering and rostrum shape was also noted among these specimens ( Fig. 11 View Figure 11 ); therefore, the two sub-clusters have been designated R. cf. djiddensis 1 and R. cf. djiddensis 2.
