|Taxonomic Notes:||The only species of this genus might belong to Mesopotamichthys.|

This fish is known from a groundwater layer near Haditha (west Iraq), accessible through a well about 3 m below Shaikh Hadeed. Water abstraction from the well itself seems to be the major threat. In addition reduced groundwater levels due to water abstraction and hydrological modifications of the water layers by the construction of a large dam close by at the Euphrates may have negatively impacted the site.
The last records of this species were from the type material in 1983; a recent comprehensive survey of the site for the species in 2012 did not find it. Its extent of occurrence (EOO) is unknown (as it is a subterranean species), but is suspected to be less than 100 km². The species is known from only one location (based on major threat of water abstraction). The species is assessed as Critically Endangered, Possibly Extinct.
This species may be more widespread in the underground karst system than currently known; however it has not appeared in surveys of other wells connected to the same aquifer and another species (Typhlogarra widdowsoni), also endemic to the same karst system, has also declined significantly.

|Population:||This species is poorly known and was always rarely found. A recent comprehensive survey of the site for the species in 2012 did not find it. The last records were from the type material in 1983.|
|Current Population Trend:||Unknown|
|Habitat and Ecology:||A cave-dwelling species.|
|Continuing decline in area, extent and/or quality of habitat:||Yes|
|Movement patterns:||Not a Migrant|
|Major Threat(s):||Water abstraction from the well itself seems to be the major threat. Also generally lower groundwater levels due to water abstraction and hydrological modifications of the water layers by the construction of a large dam close by at the Euphrates may have negatively impacted the site.|
|Conservation Actions:||There is an urgent need for conservation action and awareness raising for the only remaining site. If the species would be re-discovered, an ex-situ conservation program should be immediately considered.|
