Justification

This species' habitat is healthy. The extent of occurrence and area of occupancy is unknown because of past confusion with H. ansorgii. There is, however, unlikely to be a decline in population.

Threats:

Major Threats

The Zambezi River is a large river system in a lightly populated rural area with no immediate anthropogenic threats. There are many small tributaries where the species can survive and restock the main river in the unlikely event of a major pollution event. There are no potential alien invasive fish species that could impact on the species habitat.

Range Description:

H. szaboi is so far reported only from the Upper Zambezi River at Katimo Mulilo, Namibia. The H. szaboi/H. ansorgii complex is, however, widespread in the Upper Zambezi system and thus H. szaboi is likely to be more widespread.
