The Lachesilla asperiforceps species complex of the L. forcepeta species group (Psocodea:’Psocoptera’: Lachesillidae)

Four species of Lachesilla, from Mexico and Guatemala, are here described and illustrated. Together with L. asperiforceps Garcia Aldrete, from Mexico, Guatemala and Nicaragua, they constitute the L. asperiforceps species complex, a diagnosis of which is provided, as well as identification keys to the males and females of the species in the complex. The types and other material studied are deposited in the National Insect Collection, within the Instituto de Biologia, UNAM, Mexico City (CNIN).
