Carcharhinus amblyrhynchoides (Whitley)

( Figs. 4A , 14 A–D)

One specimen morphologically consistent with Carcharhinus amblyrhynchoides (SL-18) was examined near the main Erinchamman Kovilady market in Point Pedro in the Northern Province. It differed in NADH2 sequence from our reference specimen of this species from Malaysian Borneo (HBO-34; JQ519102 ) by 8 bp.

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