Guglielmino, Adalgisa, Sanna, Francesco & Bückle, Christoph, 2024, Remarks on the genus Emeljanovianus Dlabola, 1965 (Hemiptera: Auchenorrhyncha: Cicadellidae), with description of a new species from Italy, Zootaxa 5538 (3), pp. 264-282 : 280

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)
