First record of the subfamily Oxytorinae (Insecta, Hymemoptera, Ichneumonidae) from the Oriental region, with descriptions of two new species from Vietnam

Two new species of insects for science belonging to the genus Oxytorus, subfamily Oxytorinae, family Ichneumonidae were discovered from North and Central Vietnam.

The Oxytorinae is a small subfamily of the family Ichneumonidae (Insecta, Hymenoptera) with the single genus Oxytorus Förster and 23 described species. Species were previously known to occur in the Palaearctic, Nearctic and Neotropical Regions. This subfamily has not been found in the Oriental Region before. New information, the ichneumonid subfamily Oxytorinae is recorded for the first time from the Oriental Region. Two species, one from northern and one from central Vietnam, are described as new: Oxytorus carinatus Riedel and O. rufopropodealis Riedel.

The result is a part of the German-Vietnamese VIETBIO project. The project aims at establishing the foundation for future biodiversity joint projects through capacity building and biodiversity research in Vietnam. Field courses took place in two national parks: Bach Ma National Park in central Vietnam (June 2018) and Cuc Phuong National Park in northern Vietnam (April-May 2019).
