Measurements. See Table I.
Holotype condition. There is a hole in the mesoscutum, caused by an old pin that has been removed. Antennal flagellum pharate, covered by a translucent chitinous membrane from pupal stage.
Etymology. From Brazilian Tupi copé (back) and pucú (long), in reference to the propodeum as long as or longer than dorsellum.
Comments. We classify Leucospis copepucu in the EGAIA-Group because it has all the characters proposed by Bouček (1974a) and Darling & Cardinal (2005) for this species-group, as shown previously. Inside the group, L. copepucu resembles L. manaica in having the hind femur around 2.2× as long as broad and females with the dorsellum as long as the propodeum medially. But it is easily differentiated by having a yellow band on the scutellum, hind coxa with translucent tooth-like projection on the postero-dorsal edge, fewer teeth on the hind femur (9 versus 10‒14) and with a different shape (rhomboid apex versus acuminate apex in L. manaica ), fore wing with uncus as long as the apical process of stigmal vein (versus uncus longer than apical process) and ovipositor relatively shorter, reaching base of gaster (versus reaching scutellum). It also resembles L. egaia due to similarity of the hind coxa (punctation and tooth-like projection), ovipositor length and yellow band on scutellum, but L. copepucu possesses the dorsellum as long as the propodeum medially (versus propodeum shorter than dorsellum), hind femur 2.2× as long as broad (versus around 1.7× as long as broad), and fore wing with uncus as long as the apical process of stigmal vein (versus uncus longer than apical process).
Leucospis copepucu also lacks plicae, females have a small, latero-posterior translucent spine below the spiracle level on tergite VI, and in lateral view the male gaster has tergite VI oblique relative to tergite V. These unique features differ from those of the related species L. coxalis , L. egaia , and L. manaica .
