[email protected] Abstract. — Mellinus obscurus Handlirsch, 1888, currently recognized as a subspecies of arvensis (Linnaeus, 1758), is restored to full species status based on the unusual structure of its antennal socket. Mellinus orientalis is described from India and Nepal; its main diagnostic characters are a finely sculptured propodeal enclosure and a carina separating the propodeal posterior surface from the side.
