Remarks

Lepidonotus tenuisetosus differs from the other Mediterranean species of Lepidonotus in having elytra with fringing papillae and cylindrical microtubercules with crownlike tips ( Figure 2A ).

Distribution

This species was originally described from the Red Sea ( Gravier 1902) and subsequently reported from the Suez Canal, Indian Ocean, Pacific Ocean and Mediterranean Sea ( Barnich and Fiege 2003). In the Mediterranean, this species was first reported from the coasts of Israel and Egypt at 18–27 m depths ( Barnich and Fiege 2003). This species is new to the marine fauna of Turkey.
