Two specimens (SL-92 and SL-93) of Centroscymnus Barboza du Bocage & de Brito Capello were also collected from the deep-sea longline landing site in Mutur in the Eastern Province. Morphologically these specimens are consistent with Centroscymnus owstonii following Weigmann et al. (2016). In the tree resulting from our Neighbor-Joining analysis of NADH2 data, these specimens grouped most closely with our reference specimen of C. owstonii from Portugal. The two specimens from Sri Lanka differ from each other by 2 bp; one is identical to the reference specimen. A mature male has been deposited in the BRT Ichthyology Collection (SL-93; BRT-I 0024).

To our knowledge, this is the first documented report of this family, genus, and species from Sri Lanka. It is also the first record of this genus from the northern Indian Ocean.
