Key to the adult males of Sericostoma   in Turkey

1. In lateral view, mesoventral branch of each lateral prolongation of segment X directed ventrad......................….2

- Mesoventral branch directed posterad or posteroventrad....................................................... 3

2. Mesoventral branch of each lateral prolongation of segment X short, stout, truncate at apex ( Figs 7, 8............... S   View FIGS . ida

- Mesoventral branch long, triangular, pointed at apex ( Figs 12, 13 View FIGS )..................................... S. grusiense  

4. Mesoventral branch of each lateral prolongation of segment X half as long as dorsal branch.......................... 5

- Mesoventral branch of each lateral prolongation more than half as long as dorsal branch............................. 7

5. Mesoventral branch of each lateral prolongation of segment X nearly parallel-side and close to dorsal branch in lateral view. ................................................................................................... 6

- Mesoventral branch triangular and widely separated from dorsal branch in lateral view..................... S. flavicorne  

6. Preanal appendages digitate, smaller than obliquely truncate basoventral branches of lateral prolongations of segment X in lateral view; in dorsal view, dorsal branches of lateral prolongations each bearing small, pointed subapical projection on inner edge..................................................................................... S. taskent   sp. n.

- Preanal appendages clavate, larger than acute basoventral branches of lateral prolongations; in dorsal view, dorsal branches of lateral prolongations without small, pointed subapical projections................................ S. yuvarlakcay   sp. n.

7. Dorsal branches of lateral prolongations of segment X slender in dorsal and lateral views; mesoventral branches 2/3 as long as dorsal branches ( Fig. 36 View FIGS ); apical dilatations of ventral branches of inferior appendages small ( Fig. 38 View FIGS ).... S. pinargozu   sp. n.

- Dorsal branches of lateral prolongations thick in dorsal and lateral views; mesoventral branches of lateral prolongations more than 2/3 as long as dorsal branches; apical dilations of ventral branches of inferior appendages enlarged................. 8

8. Mesoventral branch of each lateral prolongation of segment X 4/5 as long as dorsal branch ( Fig. 26 View FIGS ); ventral branches of inferior appendages sinuate, apicomesally quadrangular in ventral view ( Fig. 28 View FIGS )...................... S. dimcay   sp. n.

- Mesoventral branch of each lateral prolongation 3/4 as long as dorsal branch; ventral branches of inferior appendages straight, apicomesally triangular in ventral view ( Fig. 24 View FIGS )................................................... S. alakir   sp. n.
