Zyzzyx is a monospecific genus of sand wasp, containing a brightly coloured, medium-sized species, Zyzzyx chilensis. It is primarily a predator on flies, but has been observed to consume skippers.[8] "Zyzzyx" is a replacement name proposed in 1937 by V. S. L. Pate for Therapon, originally described by J. Parker in 1929.[4]

Z. chilensis is found in Chile, Peru, and Argentina.[3]
