Rhizoprionodon oligolinx Springer

(Figs. 4B, 14 K–L)

Three specimens that were morphologically consistent with Rhizoprionodon oligolinx were examined from the Supparmadam (SL-22) and Kottadi (SL-53, SL-54) markets in Point Pedro in the Northern Province. In the tree resulting from the Neighbor-Joining analysis, they grouped most closely with our reference specimen of R. oligolinx (BO-475; JQ519096) collected from Malaysian Borneo. They differed from one another by 0–3 bp and from the reference specimen by 8–9 bp.

This name is in current use for this species in Sri Lanka (e.g., De Silva 1984 –1985, 2006, 2015; De Bruin et al. 1995; Morón et al. 1998).
