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.

A syndrome of hypotonia, psychomotor retardation, seizures, delayed and dysharmonic skeletal maturation, and congenital fibre type disproportion.

Three unrelated Puerto Rican boys, ranging in age from 3 to 4 years, had marked, central, non-progressive hypotonia, chronic constipation, severe psychomotor retardation, seizures or abnormal electroencephalograph or both, abnormal dermatoglyphics, delayed bone age, dysharmonic skeletal maturation, and preponderance and larger size of type 2 muscle fibres. Additional findings included narrow, high arched palate, prominent nasal root, long philtrum, distended abdomen, and drooling from open mouth. Two of the three patients also had undescended testes, hypertelorism, and tapered fingers. Birth weight, postnatal physical growth, and head size were average. Family and gestational histories and laboratory evaluations were normal. The combination of features observed in the three boys appears to be distinct and to represent a new syndrome.
