Remarks.

This species was described from 15 specimens, 13 females and 2 males, but no primary type was selected. One of the females is here designated as lectotype, with labels "Jacksonville, Fla", “Type”, "Type No.27642, U.S.N.M.", " Euplectrus marginatus Ashm.", " Euplectrus marginatus Lectotype Gordh 1978". This specimen was selected as lectotype by G. Gordh but was never validated. The redescription above is based on the lectotype, as are also the illustrations. The lectotype lacks entire right antenna and left antennal flagellum.
