Etymology
'post-marginal' originates from Latin-derived elements: the prefix 'post-' (Latin 'post') meaning 'after', and 'marginal' from Latin 'margo, marginis' meaning 'edge' or 'border'.
'post-marginal' was formed in English by combining the Latin prefix 'post-' with the adjective 'marginal' (itself from Old French/Latin); the compound has been used in technical and scientific English (especially biology and entomology) to mean 'after the margin'.
Initially it had the literal sense 'after the margin'; over time it retained that basic sense and acquired a specialized technical meaning in fields like entomology referring to a specific vein or area just beyond the wing margin.
