Type locality West of Iles Crozet, -46.2667, 48.45°, 2926 m. McIntosh states the location is between Prince Edward and Kerguelen Islands, and Zhang & Hutchings (2021) repeat this, but the geolocation McIntosh gives is close to Iles Crozet. Petta assimilis was collected west of the Iles Crozet group. The species has no association with the farther east Kerguelen Islands group. [details]
