Definition:

The usual second principal longitudinal vein of the wing. In mosquitoes, two-branched with subcosta-one ending at the costa and subcosta-two connected to the radius.

Explanation:

Although culicidologists have customarily treated the small part of this vein connected with the radius as the subcostal crossvein, the traditional usage outside of mosquitoes since Comstock (1918) has been to consider this as subcosta-two. This has continued to the present and is accepted here.
