Abstract

In this paper we describe four new species of Stethantyx Townes (Ichneumonidae: Tersilochinae) from Ecuador and Peru characterized by the fore wing with first and second abscissae of radius meeting at right angle: S. erwini Khalaim \& Saaksjarvi, sp. nov., S. radiata Khalaim \& Saaksjarvi, sp. nov., S. rufispa Khalaim \& Bordera, sp. nov. and S. undulata Khalaim \& Saaksjarvi, sp. nov. Second part of the key to species of Stethantyx occurring in Western Amazonia is given. Additionally, S. altamira Khalaim \& Broad and S. aprica Khalaim \& Broad are recorded from South America for the first time, and new data on distribution of S. alajuela Khalaim \& Broad, S. amazonica Khalaim \& Saaksjarvi, S. heredia Khalaim \& Broad, S. orellana Khalaim \& Saaksjarvi, S. sinuata Khalaim \& Saaksjarvi and S. trepida Khalaim \& Saaksjarvi in South America are provided. Male of S. orellana is recorded for the first time.
