Synagris
Synagris is an Afrotropical genus of large potter wasps. Several Synagris wasps are strongly sexually dimorphic and males bear notable morphological secondary sexual traits including metasomal lamellar or angular protruding structures and hornlike or tusklike mandibular and/or clypeal projections.
The few species of Synagris with known biology are also notable for guarding their nests and even attending and feeding their larvae during their development, a primitively social behavior unusual among eumenines, which normally practice mass provisioning.
There are 4 subgenera and 28 species currently recognized.
