A unique structure found in all Eucoilinae. The dorsal-most part of the mesoscutellum is modified into a large to small plate; a glandular release pit is located towards the posterior of the plate. The function of the plate and its associated pit is presently unknown. Dissections by the author have revealed that a large gland is present beneath the surface of the plate, with tubular ducts leading to pores within the pit of the plate.
