A New Thyreodon Brulle (Hymenoptera: Ichneumonidae) from South Texas

Charles C. Porter


Thyreodon rivinae n. sp. was collected during July 1979 from undergrowth of Rivina humilis Linnaeus in Celtis woods at Bentsen Rio Grande Valley State Park near Mission, TX. The salient diagnostic features of T. rivinae are its enlarged ocelli (which almost touch the compound eyes laterally), yellow flagellum, and black fore wing with a large hyaline blotch in the discocubital and 2nd discoidal cells.
