Other species previously placed in Neogonatopus are removed as follows: brunnescens Perkins, erythrodes Perkins and obscurissimus Perkins all transferred to Gonatopus; mimus Perkins transferred to Agonatopus; mimoides Perkins transferred to Epigonatopus; and longitarsus (Ashmead) transferred to either Pseudogonatopus or Haplogonatopus.Illustrations are included for most known males and females of all species. Present distributions and some rearing information are also given.
