Urogymnus acanthobothrium Last, White & Kyne, 2016e: 163, Figs 1 –7. Holotype: WAM P. 34488-001. Type locality: West Arm of Cambridge Gulf, Western Australia.

Local synonymy: Urogymnus acanthobothrium— Last et al., 2016e: 163, Figs 1 –7 (Gulf of Papua); Last et al., 2016a: 613 (southern PNG) ; White et al., 2018: 264, figs (PNG).

PNG voucher material: None.

Remarks: First recorded from PNG by Last et al. (2016e) based on records from observers on prawn trawl vessels in the Gulf of Papua. Holotype and several other specimens were caught in rivers in Northern Australia, and it is thus likely to inhabit the riverine areas in the Gulf and Western Provinces of PNG.
