Gibberrhynchium
Gibberrhynchium is a small Afrotropical genus of potter wasps.
It was considered to be monotypic with the only species being Gibberhynchium masariforme, which is widely distributed though Central Africa.
A second species, Gibberrhynchium gibber, was described by Josef Gusenleitner in 2002 from the Democratic Republic of Congo.
