(2017) , one of the fisheries we targeted was the deep-sea longline fishery in Mutur, Trincomalee Harbor in the Eastern Province. We were fortunate that on the second of the two days we spent at that location, fishers returned with dead bycatch retained for us. Fishing at 350 fathoms, their catch that day included a specimen (SL-107) of Planonasus allowing us to confirm the novelty of this, only the second known member of the genus. The species was recently described as Planonasus indicus (see Ebert et al. 2018 ). The original description was based on a holotype from India and our specimen from Sri Lanka ; the latter has been designated a paratype and deposited in the BRT Ichthyology Collection (BRT-I 0029). Ebert et al. (2017) originally reported this species from Sri Lanka as Planonasus parini Weigmann, Stehmann & Thiel.
