Among the large family of the Eulophidae (Chalcidoidea), the Euplectrini are closely related to the Elachertini and form with them the subfamily Elachertinae. In common with the genus Elachertus, Spin., they have antennae with a 4-jointed funicle, complete parapsidal furrows, often longitudinal furrows on the scutellum and a petiolated abdomen. They are, however, easily distinguished by the large size of the spurs of the hind tibiae, the longest being generally more or less as long as the first two tarsal joints together.
