A key to the species of the genus Emeljanovianus is given by Zhang et al. (2013). We present the modified second part of this key (concerning the “medius-group”) beginning with guide number 4.

4. Processes of pygofer lobe long, finger-shaped, apically serrate (Figs 2G, 3A); gonopore large (Fig. 2A)................................................................................................. E. hyperprocessatus sp. n.

- Processes of pygofer lobe short, thorn-shaped, smooth (Figs 7C, 10F); gonopore smaller (Figs 7A, 10D)................ 5

5. Subapical processes of aedeagus basally of gonopore, directed basad (Fig.10D)..................... E. hilaris (Melichar)

- Subapical processes of aedeagus laterally of gonopore, directed laterobasad (Fig. 7A).......... E. medius (Mulsant & Rey)
