Justification:
Synodontis robbianus is only known from Nigeria; its EOO and AOO are estimated as less than 5,000 km² and 500 km² respectively, so we can say that the species meets the thresholds for Endangered. However, there are no signs that ongoing habitat decline will affect this hardy airbreathing species and there are no data available on population fluctuation. However the species is restricted to only two locations. With a potential loss of habitat the species therefore qualifies for Vulnerable D2.
