Stenaelurillus feral sp. nov. is most similar to S. tettu Logunov, 2020 in having ventral tibial apophysis situated prolaterally, but retrolateral tibial apophysis without serrated inner margin and with blunt tip in latter species (compare Figs 1E–F , 2A, D and Logunov 2020: fig. 23). Etymology The specific epithet refers to the acronym ‘FERAL’, the Foundation for Ecological Research, Advocacy and Learning campus, from where the specimen was collected.
