Parameristomerinx copelandi—a new genus and species of Afrotropical Pachygastrinae and a new generic synonym of Dolichodema Kertész (Diptera: Stratiomyidae)

A new genus and species, Parameristomerinx copelandi gen. et sp. n. (Diptera: Stratiomyidae: Pachygastrinae) is described from material from Kenya. This genus is similar to the Afrotropical genera Meristomerinx Enderlein, 1914 and Meristomeringina James, 1952. A new generic synonym is also proposed, Nemodema Lindner, 1958 = Dolichodema Kertesz, 1916, syn. n. A key is included for the six genera related to Meristomerinx.
