What is "usiququmadevu"

Usiququmadevu is a figure from Zulu mythology. She is said to be a monstrous deity, hunchbacked and with a beard, who eats children. According to legend, one day she came upon the children of a chief; as they were unguarded, she quickly swallowed them. The chief discovered what had happened, and instantly set out to find her. Soon he did, and killed her by stabbing her in the hump; his children emerged unscathed from her mouth.

Usiququmadevu is said to have a husband of the same name.
