The color photos were made with a Nikon SMZ 1000 stereomicroscope and a Nikon DS-5M camera. To eliminate reflections from the metallic and shiny body, a dome light manufactured as described by
Pods of pigeon pea were collected in several different parts of the Dominican Republic and were placed in plastic bags with holes for ventilation and prevention of condensation inside the bags. The samples were brought to the laboratory where the pods were opened and fly larvae, pupae and adults were counted. The larvae and pupae were placed in plastic containers (9 × 9 cm) with a piece of cloth at the opening to facilitate aeration. The emerging parasitoids and imagines of the Asian fly were killed and stored in vials with ethanol.
Measurements were taken using the Nikon stereomicroscope mentioned above, using a eyepiece micrometer at 80 times magnification. The female holotype and ten paratypes of each sex were measured.
