Diagnosis. Oxypoda amica belongs to a group of Nearctic species with the copulatory piece of the internal sac extended in a long flagellum. Externally the species of this group are very similar, and O. amica can be recognized among them only by the distinct shape of the aedeagus ( Figs. 15–17 ) and spermatheca ( Fig. 18 ).

Discussion. The types of O. amica , Anc. sollemnis , O. vetula , O. neptis and O. schaefferi are similar in external characters and in the shape of the aedeagus (including the sclerites of the internal sac) and spermatheca.

Distribution. Oxypoda amica is widespread in the eastern United States. It is known from Iowa, Kansas, Missouri, Kentucky, New York, New Jersey, Tennessee, North Carolina and Louisiana.
