Key to the Kybos virgator group (anal collar process long and slender, aedeagus with lateral processes)

1. Aedeagus processes (lateral view) broader than shaft; anal collar process moderately long; on Salix eleagnos (and possibly other Salix spp.)....................................................................... K. digitatus (Ribaut)

- Aedeagus processes (lateral view) slender, less broad than shaft ( Fig. 5 A); anal collar process very long ( Fig. 5 E)......... 2

2. Apodemes of 2nd abdominal sternum very short, not reaching hind margin of 3rd sternum (Fig. 6C); apodemes of 2nd abdominal tergum well developed (Fig. 6A); on Salix alba , Salix eleagnos ................................ K. albitalicus sp. nov.

- Apodemes of 2nd abdominal sternum long, extended beyond hind margin of 3rd sternum (Figs 7B,7D); apodemes of 2nd abdom- inal tergum very short.................................................................................. 3

3. Aedeagus processes (dorsal view) parallel to shaft; on Salix pentandra ...................... K. albilacustris Tishechkin

- Aedeagus processes (dorsal view) form an angle of at least 45° to the shaft........................................4

4. Apodemes of 2nd abdominal sternum twice as long as wide (Fig. 7B); mainly on Salix alba , S. fragilis .... K. virgator (Ribaut)

- Apodemes of 2nd abdominal sternum at most little longer than wide (Fig. 7D); on Salix pentandra (?).. K. volgensis (Vilbaste)
