description: Key to the microphthalmous Lathrobium species of Turkey
The keys to Turkish microphthalmous species in Assing (2001, 2007) and Anlaş (2018) are modified as follows:
1. Eyes strongly reduced, without ommatidia................................................................. 2
- Eyes weakly reduced, with> 30 ommatidia................................................................. 4
2. Eyes completely reduced, without ommatidia or pigmentation; aedeagus almost symmetrical (Assing, 2001: figs 30−36).................................................................................. L. brignolii Bordoni, 1980
- Eyes barely visible in dorsal view, without distinct ommatidia, but with pigmentation; aedeagus strongly asymmetrical... 3.
3. Head with pronounced microreticulation; pronotum narrower in relation to head; aedeagus smaller, 0.60–0.65 mm (Assing, 2007: figs 1−12)................................................................. L. distortum Assing, 2007
- Head with shallow microreticulation; pronotum broader in relation to head; aedeagus larger, approximately 0.9 mm (Assing, 2007: figs 13−22)................................................................. L. deforme Assing, 2007
4. Micro-pubescence on median posterior area of female sternum VIII absent; area with modified dark setae of male sternum VII confined to posterior median emargination; apical sclerotized structure of internal sac of the aedeagus shaped like a spoon apically in lateral view (Figs 1-10)............................................................ L. kacari sp. n.
- Micro-pubescence on median posterior area of female sternum VIII present; area with modified dark setae of male sternum VII extending further anteriad.............................................................................. 5.
5. Apical sclerotized structure of internal sac in the aedeagus shaped like a hook or a barb in lateral view................. 6.
- Apical sclerotized structure of internal sac in the aedeagus shaped like a straight spine or protruding as two parts in lateral view............................................................................................... 7.
6. Male sternum VIII with pubescence present along median line, with slightly smaller apical emargination; apical sclerotized structure of internal sac of the aedeagus shaped like a barb in lateral view (Assing, 2001: figs 17−21; Anlaş, 2018: figs. 18−24)........................................................................ L. uncinatum Assing, 2001
- Male sternum VIII without pubescence along median line, with larger apical emargination; apical sclerotized structure of internal sac in the aedeagus shaped like a hook in lateral view (Assing, 2001: figs 8−16; Anlaş, 2018: figs. 11−17).................................................................................. L. bodemeyeri Bernhauer, 1903
7. Lighter colouration of the forebody; aedeagus smaller (0.9 mm long); apical sclerotized structure of internal sac of the aedeagus shaped like a straight spine in lateral view (Anlaş, 2018: figs. 1−10)........................... L. newtoni Anlaş, 2018
- Darker colouration of the forebody; aedeagus larger (1.15−1.20 mm long); apical sclerotized structure of internal sac of the aedeagus protruding as two parts in lateral view (Figs. 10-18)....................................... L. celiki sp. n.
