alternative definition added over 13 years ago by Istvan Miko
Portion of the forewing vein complex that is along the leading edge of the wing
basal to the stigmal vein; usually measured from the point at which the submarginal vein
touches the leading edge of the wing to the point at which the stigmal vein and postmarginal
vein unite (sometimes there is a narrow membranous region anterior to the marginal vein and
in some families, e.g. Signiphoridae, defined to include what is likely the parastigma of most
other chalcids).
