Amphoterus Bezzi, 1915: 116. Type species: Amphoterus cribratus Bezzi (by original designation).

Notes.

Amphoterus species have bare eyes (not setulose as stated in Ssymank et al. 2021) and the antennae are elongate (short in Eumerus and Megatrigon ) with a bare antennal arista. The body is dark (brown or black) and strongly punctate. The males are broadly dichoptic. The wing venation resembles that of Eumerus and Megatrigon with a nearly straight vein R4+5 and a recessive vein M1.
