The Nearctic species of <i>Saotis </i>Fцrster, 1869 (Hymenoptera: Ichneumonidae: Ctenopelmatinae)
Sixteen North American species of the genus Saotis Fцrster, 1869 are reviewed. Most of them have Holarctic distribution. Four new species of this genus are described: S. erythropleura sp. nov., S. rufigaster sp. nov., S. tinctor sp. nov. and S. truncator sp. nov. The Nearctic subspecies of four Holarctic species are described and redescribed: S. brevispina lissor subsp. nov., S. granulator albator subsp. nov., S. renovata rufipes subsp. nov. and S. pygidiator nearctor Kasparyan, 2009. A key to the Nearctic species of Saotis is given. The status of the European Iskarus Kolarov, 1987 as a monotypic subgenus of the genus Saotis is justified due to peculiarities in structure of its ovipositor.
