Tribe Orfeliini
52 nearctic species in 11 genera(1)
Most Orfeliini can be distinguished from other Keroplatidae by the combination of cylindrical antenna (vs. laterally compressed in Keroplatini) and branches of CuA divergent (vs. convergent near base in Macrocerinae). Some have flattened antennae and must be distinguished from Keroplatini using microscopic characters.
