Comments.

Generally this species can be confused with other Adialytus species on Sipha aphids, but it is immediately distinguishable by its very short vein R1 (0.7-0.8 × as long as pterostigma) (Fig 3C). Also, its petiole has much stronger anterior and spiracular tubercles (Fig 5C). Most of the metasoma is yellowish, while in other Adialytus species it is uniformly brown to dark brown.
