Character

Posterior margin of upper mesepimeron [59]

Description

A notched upper mesepimeron likely represents an opening for the metathoracic spiracle or a remnant of where the metathoracic spiracle once was (Gibson & Huber, 2000), though this has yet to be proven through dissections. Its phylogenetic significance may be problematic because it can be variable even within species (e.g. Halticoptera dimidiata (Pteromalidae) has a distinct notch only in some specimens). For eupelmids with a fully expanded acropleuron the notch is usually dorsal on the horizontal margin of the acropleuron.
