Prodiscriminal line [39]

Description

The prodiscriminal line is a longitudinal division on the ventral surface of the fused mesepisterna mesally, corresponding internally to a discriminal lamella. Richards (1956) referred to the prodiscriminal line as the median sternal groove. Externally, the line can be indicated as a uniform groove or sculptured channel but we chose not to separate the different structures into different states. A channel-like groove may be very faint, but still present. In Neanastatinae (Eupelmidae), what likely is the discriminal lamella sometimes is evident through the cuticle, but is not present externally and therefore was coded as state 0. Citations: Schauff (1984: 24); Krogmann & Vilhelmsen (2006: 13).
