A revision of the genus Rhinotorus Förster, 1869 (Hymenoptera, Ichneumonidae, Ctenopelmatinae), with descriptions of three new species and an illustrated identification key

The genus Rhinotorus Förster, 1869 is revised. Thirteen species are recognized including 3 species that are new to science (R. jussilai sp. nov., R. campester sp. nov., R. tarsilatus sp. nov.). Saotis brachycerus (Kasparyan & Kopelke, 2009) comb. nov. is considered to be a member of the genus Saotis. Rhinotorus similis (Brischke, 1892) is tentatively recorded from Austria and Sweden for the first time. A number of new host records are also provided: Cladius pectinicornis (Geoffroy, 1785) for R. leucostomus (Gravenhorst, 1829), Nematus lucidus (Panzer, 1801) for R. nasutus (Gravenhorst, 1829) and N. papillosus (Retzius, 1783) for R. jussilai sp. nov.
