The genus Messua was synonymized with Zygoballus by Eugène Simon in 1903. After examining the type specimen for Messua desidiosa, Simon commented that it was "much less divergent from typical Zygoballus than [the Peckhams'] description would indicate."[2] This was reversed by Wayne Maddison in 1996, and Messua restored as a valid genus. Maddison also transferred several species that had previously been placed in Metaphidippus into Messua.[3]
