Genus Simocephalus Schoedler, 1858

Eight species of Simocephalus were encountered in our survey. Simocephalus exspinosus (Koch) was restricted to the central plateau, while S. punctatus Orlova-Bienkowskaja was only found in the north. S. mixtus Sars was also detected in the north, but a morphologically similar species ( S. cf. mixtus ), with high divergence (14.39%) occurred on the central plateau. A smaller difference was found within the S. punctatus complex (4.6%). Both of these cases seem to involve cryptic species.
