Lectotype ♀ (USNM), designated here, examined. Material. Type material: ♀ lectotype of Euplectrus pachyscapha (USNM). Diagnosis. Lower face medially reddish-brown, pale area reaching to outer lateral margins of toruli (Fig. 449); head below level of eyes distinctly pointed (Fig. 449); female scape long with ⅕ reaching above level of vertex (Fig. 452); dorsellum anteriorly with a groove that covers ⅓ the length of dorsellum and is divided by longitudinal carinae ; legs yellowish-brown with hind coxa slightly darker (Fig. 448); petiole 0.5 x as long as wide; gaster yellowish-brown in median ⅓ with lateral margins dark brown, and with a dark brown round spot posteromedially (Fig. 450). Description. Female. Length of body 2.4 mm. Antenna with scape and pedicel yellowish-brown, flagellomeres pale brown (Fig. 451); scape long with ⅕ reaching above level of vertex (Fig. 452). Mandibles and palpi yellowish-white. Head black and shiny, lower face medially reddish-brown, pale area reaching to outer lateral margins of toruli, parts between pale area and eyes black (Fig. 449). Frons close to eyes with two rows of setae. Vertex inside ocellar triangle with very weak reticulation, outside triangle smooth. Occipital margin with a carina behind ocellar triangle. Mesosoma black and shiny (Fig. 448). Each sidelobe of mesoscutum with 16 setae. Scutellum 1.0 x as long as wide; with weak and engraved reticulation and with elongate meshes in anterior ⅓ and isodiametric in posterior ⅔, posterior margin smooth. Dorsellum with a groove along anterior margin that is divided by longitudinal carinae, medially 0.3 x as long as length of dorsellum.

HE/MS/WM = 1.7/1.0/1.1; POL/OOL/POO = 5.6/3.4/1.0; OOL/DO = 1.8; WE/WF/WH/HH = 1.0/3.0/5.0/3.9; WH/WT = 1.0; PM/ST = 1.5; TS1/TS2/LT/LT1/LT2/LT3/LT4 = 3.5/2.3/7.1/2.3/1.5/1.0/1.8; LP/WP = 0.5; MM/LG = 1.3. Male. Not found. Hosts and biology. Unknown. Distribution. USA (Kansas) ( Girault 1917a ). Remarks. Euplectrus pachyscaphus was described from an unspecified number of female and male specimens. The only remaining specimen in USNM (M. Gates personal communication) is a female which is used for the redescription above. This specimen is labeled "Type 21159 U.S.N.M." and a handwritten label "Euplectrus pachyscapha Girault ♀ type", and is here designated lectotype.
