Tegumental glands in the third gastral tergites of male Parischnogaster nigricans serrei (Du Buysson) and P. Mellyi (Saussure) (Hymenoptera Stenogastrinae)

Abstract

Tegumental glands, described for the first time, clustered along the anterior margin of the third gastral tergite of male Parischnogaster nigricans serrei (Du Buysson) and P. mellyi (Saussure) produce a secretion whose function may be connected with the white stripes display and mating system of these species. © 1983 Masson.
