Character

Length of postmarginal vein of fore wing [84]

Description

This applies to the tubular portion of the vein only, not to any pigmented remnant. The base of the postmarginal vein (pmv) is measured at the juncture of the vein with the stigmal vein (Graham, 1969). For state 2, the costal cell is assumed to be longer than the stigmal vein (stv) including the stigma. In Anorasema (Eucharitidae), the pmv is extremely long and extends to the apex of the wing but is still shorter than the costal cell and therefore coded as state 1. The pmv is also more or less longer than the costal cell in Neanastatus (Eupelmidae), but regardless of legnth is coded as state 1 because the costal cell is hypothesized to be secondarily shortened because the parastigma is integrated with the marginal vein (see character 145). In some Eupelminae, the pmv is exactly the same length as the stv (e.g. Eupelmus urozonus) and was scored as state 1, but without confidence.
