Brief Summary
provided by Catalog of Hymenoptera in America North of Mexico
The genus Sphenolepis Nees, 1834 (Hym. Ichn. Aff. Monog., v. 2, p. 265), along with its synonym Peltephorus Erdos, 1961 (Mus. Nat. Hungarici, Ann. Hist. Nat. 53: 483, 489), has been placed as a synonym of Tetrastichus Haliday by Boucek, 1961 (Mus. Nat. Pragae, Acta Ent. 34: 475). Sphenolepis is a wingless, aberrant form. It is, nevertheless, in Boucek's opinion, the same genus as Tetrastichus. Since it has priority over Tetrastichus, Boucek expressed his intention to petition the International Commission to suppress it. However, Sphenolepis and Tetrastichus can, and should, be separated generically.
