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.
