The subgenus is now divided into the nigristrigatum and nemorale species groups; some formerly proposed groups are suppressed. New locality records are given for several species, and Simulium (Pternaspatha) pulchrum and prodexargenteum are redescribed. Simulium punctativentris is synonymized with S. simile. New species are horcochuspi (Argentina) (nigristrigatum group) and bordai (Bolivia), hectorvargasi (Chile), quechuanum (Chile and Argentina) and stelliferum (Chile) (nemorale group)"--P. 201.14119395 bytesapplication/pdfen-USQH1 .A4 vol.147, art.4, 1972SimuliumSimulium -- Geographical distribution.Simuliidae -- South AmericaSimuliidae -- South America -- Geographical distribution.Insects -- South AmericaInsects -- South America -- Geographical distribution.text
