Zusammenfassung:The dryopid genus Helichus Erichson is subdivided into Helichus s. str. and Postelichus gen. nov.; type species respectively are lithophilus Germar and thoracicus Hinton. The two genera are consistently separable on the basis of several external characters as well as internal reproductive features in both sexes. Six valid species are presently known for Postelichus and ten for Helichus, but additional species remain to be described. Both genera are restricted to the Western Hemisphere.
