Sassacus cyaneus
Sassacus cyaneus is a species of jumping spider. It used to be the only described species of the genus Agassa, but was transferred to the genus Sassacus in 2008. It seems to be closely related to S. papenhoei, but differs in the form of the carapace.

S. cyaneus is native to Sonora in Mexico, and parts of the United States.
