EOL Text

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.

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.
