Zeta

potter wasps

Zeta is a small neotropical of in the Eumeninae, . The genus currently contains four , with most having restricted geographic distributions. Three species are limited to specific regions: Zeta confusum is to Cuba, Zeta abdominale occurs on several Caribbean islands, and Zeta mendozanum is restricted to the Monte and Patagonia regions of Argentina. Zeta argillaceum is the exception, being widespread and common across much of the neotropics.
