The Gall Associates of Asphondylia poss. swaedicola Kieffer & Jörgensen (Diptera: Cecidomyiidae) on Suaeda divaricata Moq. (Amaranthaceae) in the Semiarid Argentina and Summary of Parasitic Hymenoptera Associated with Suaeda Worldwide.

We report on Asphondylia poss. swaedicola Kieffer & Jörgensen inducing apical stem galls on Suaeda divaricata Moquin-Tandon in the Monte region of Argentina. The putative inquiline gelechiid Scrobipalpula patagonica Povolný is confirmed as an associate of A. poss. swaedicola galls. The following hymenopteran parasitoids are associated with this system: Torymus nr swaedicola (Kieffer & Jörgensen), Aprostocetus sp., Horismenus sp., Bracon (Bracon) sp., Chelonus (Microchelonus) sp., Apanteles sp., Zaeucoila robusta (Ashmead), and Goniozus nigrifemur Ashmead. The Horismenus sp., Z. robusta, and G. nigrifemur are reported as associates of Suaeda for the first time. A total of 28 genera and 31 species of parasitoids known to be associated with Suaeda spp. worldwide and their associations are tabulated.
