Material
Type material: ♀ neotype of Euplectrus comstockii (USNM). Additional material: 3♀ 4♂ (USNM) from the series of specimens mentioned by Schauff and Janzen (2001)[1], from which the neotype was selected.
Diagnosis
Lower face medially yellowish-brown (female, Fig. 682) or white (male, Fig. 683), pale area reaching slightly outside of level of outer lateral margin of toruli, part between pale area and eyes black (female) or dark brown (male); scutellum smooth in anteromedian ⅔, remaining parts with very weak reticulation; legs yellowish-white, except yellowish-brown hind coxa (Fig. 681); petiole 0.7× as long as wide; gaster dark brown, anterior ½ with a round yellowish-brown spot (female, Fig. 684), or anterior ½ white with dark brown lateral margins (male, Fig. 685); male scape slightly expanded and widest apically, 3.3× as long as wide (Fig. 687), sensory pores confined to anteroventral ½.

Female. Length of body 1.9 mm. Antenna with scape and pedicel yellowish-brown, base of scape whitish, flagellomeres brown (Fig. 686). Mandibles and palpi yellowish-white. Head black and shiny, vertex dark reddish-brown almost black, lower face yellowish-brown medially, pale area reaching slightly outside of level of outer lateral margin of toruli, part between pale area and eyes black (Fig. 682). Frons close to eyes with two rows of setae. Vertex smooth. Occipital margin with a weak carina behind ocellar triangle.
Mesosoma black and shiny (Fig. 681). Each sidelobe of mesoscutum with 12 setae. Scutellum 1.0× as long as wide; smooth in anteromedian ⅔, remaining parts with very weak reticulation. Dorsellum anteriorly with a groove that is divided by longitudinal carinae, groove medially 0.4× as long as length of dorsellum.
