Dusona abdominator is a species of parasitic wasp belonging to the family Ichneumonidae, subfamily Campopleginae.
In females are parts of the mandibles, legs excluding the trochanters and coxae, apex of the post petiole and the rest of the abdomen dark red (though base of second abdominal segment usually with a black spot).
Coloration of males is similar, but with the mandibles, trochanters and coxae mottled with yellow, and with a more distinct black line on the third abdominal segment.
First abdominal segment evenly curved on the upper side and without lateral impressions.
The species is most easily distinguished by the extensive red coloration of the abdomen, the sculpture of the propodeum and the structure of the first abdominal segment.
