First Description of the Male of the Predaceous Midge Genus Notiohelea Grogan and Wirth (Diptera: Ceratopogonidae)

Abstract

The male of Notiohelea pilosa Spinelli and Grogan is described and illustrated from specimens collected in association with females in the Valdivian rain forests of Nahuel Huapi National Park, in Argentinean Patagonia and from specimens collected in nearby Chile. The male of N. pilosa is readily distinguished from those of Macrurohelea species by the presence of palisade setae on tarsomeres 1–3 of the hindleg.
