| Review (by Malcolm Storey) | First half of Perkin’s keys to selected subfamilies of Ichneumonidae, including the key to subfamilies (p3). More than 20 subfamilies are recognised and the key runs to 43 couplets. The Ichneumoninae section begins with a key to tribes, followed by each tribe with keys to genera and species. The large tribe Ichneumonini is continued in the separately published second part, along with subfamilies Alomyinae, Agriotypinae and Lycorininae. The remaining subfamilies are not covered here. Can be downloaded from the Royal Entomological Society’s website. |
| Examine |  Stereo Microscope |
| Specimen Preparation | Pinned and set specimens |
| Identification difficulty | The subfamily key is challenging; Gavin Broad’s nicely-illustrated manuscript key is much better. |
