Remarks.

According to LaSalle and Schauff (1992) the lectotype specimen of Euplectrus chapadae designated by them was a male. However, the specimen examined, which also has the lectotype label by LaSalle & Schauff, is a female.

The lectotype specimen is with head detached from the body and glued separately to the card. The specimen lacks all flagellomeres except the flagellomere 1 on both antennae, and left fore tarsus.
