Carvalho and Southwood (1955) made a world revision of the Cyrtorhinus-Mecomma complex, and listed 11 species and three subspecies of Mecomma. Those reported from North America are: ambulans (Fall.), gilvipes (Stål), luctuosa (Prov.), luctuosa pacifica Carv. and South., antennata Van D., and mimetica Carv. and South.
In the present paper, Mecomma bradora, n.sp., is described from Quebec, and the distinguishing external and genitalic characters are given. Additional notes on the habits, morphology, and distribution of Mecomma mimetica are given, and the status of Mecomma dispar (Boheman) in North America is discussed.
