Binomial name
Caecieleotris morrisi

It is only known from museum specimens that were collected in the 1990s.[3] Since then the cave system has been flooded because of a dam. Recent surveys have not been able to relocate the species and it might be extinct.[3]

The generic name is a compound of the Latin caecus meaning blind suffixed with Eleotris, the type genus of the Eleotridae and specific name honours the cave diver, speleologist and conservationist Thomas L. Morris who discovered this species and collected the type specimen.[4]
