Triaenodon obesus (Rüppell) (Fig. 4A) A tissue sample was taken from a frozen specimen of Triaenodon obesus (SL-119) that had been collected earlier in 2018 from the Negombo fish market in Negombo in the Western Province. This specimen has now been deposited in the BRT Ichthyology Collection (BRT-I 0031). This specimen is morphologically consistent with T. obesus. It clustered most closely with our reference specimen of this species (KA-126; JQ518656) from Indonesian Borneo included in the Neighbor-Joining analysis. It differed from this specimen in NADH2 sequence by 7 bp. This is the name currently applied to this species in Sri Lanka (e.g., De Silva 1977, 1984 –1985, 2006, 2015; De Bruin et al. 1995; Joseph 1999).
