Character

Length of costal cell of fore wing [81]

Description

The costal cell is the wing membrane anterior to the submarginal vein, between the humeral plate and the junction of the submarginal vein with the wing margin. In some taxa ( e.g., Hybothoracini, Chalcididae), the marginal vein extends horizontally before the actual wing margin, and the apex of the costal cell is considered to end at the base of the marginal vein. Neanastatus (Eupelmidae) has a costal cell that is less than one-third the wing length, but this unusual structure is because the “marginal” vein is unusually long and likely is a composite of both the marginal vein and the parastigma of the submarginal vein because the parastigmal sensilla are on the apparent marginal vein.
