''Microsynodontis'' is a genus of upside-down catfishes native to Africa. ''Microsynodontis'' species are occasionally imported for the aquarium trade. Very little is known about their biology.〔 ==Description== It can be difficult to identify species of ''Microsynodontis'' as their coloration can be highly variable within each species, and color patterns may even change as a fish grows; to identify based on coloration, an understanding of the limits of variation is necessary.〔 ''Microsynodontis'' species express sexual dimorphism. Males can be distinguished by the presence of a conical genital papilla immediately posterior to the anus; in females, this papilla is smaller and has a flattened tip. Males also have a much denser aggregation of tubercles on the head. In ''M. hirsutus'' these tubercles are longer than in the other species.
