First record of the subfamily Eucerotinae (Hymenoptera, Ichneumonidae) from the mainland Afrotropics, with a description of a new species

The ichneumonid subfamily Eucerotinae has been thought to be almost absent from the tropics, with the only known Afrotropical species found in Madagascar. We report the subfamily as present in the mainland Afrotropics and describe a new species, Euceros ibex Hopkins, Nascimento & Santos, sp. nov ., from Uganda and Cameroon. The subfamily was likely not observed in the mainland Afrotropics before because of low abundances and insufficient sampling. More Eucerotinae likely remain to be discovered in tropical Africa and Asia, although tropical America may genuinely have few eucerotine species. Much more extensive sampling will be needed before it is possible to make confident estimates of how eucerotine diversity is distributed globally.
