Contributions of the longhorned beetles knowledge of Turkey by the subfamilies Prioninae, Lepturinae, Dorcadioninae and Lamiinae (Coleoptera: Cerambycidae)Abstract : The present work presents new contributions to the knowledge of the subfamilies Prioninae, Lepturinae, Dorcadioninae and Lamiinae that are 4 of 5 richest subfamilies in terms of diversity among cerambycids, of Turkey. The specimens for this study were collected over various years (2001-2012) from different localities in Adana, Balıkesir, Bolu, Düzce, İçel, Kahramanmaraş, Karaman, Muğla, Niğde and Osmaniye provinces in Turkey. As a result of the work, a total of 58 species (25 of them into subspecies level) belonging to 37 genera of 20 tribes of 4 subfamilies were determined from Turkey. One species of them is recorded from Turkey for the second time. Two species of them are the first record for Southern Turkey. Also, four species for Central Anatolian Region, six species for Mediterranean Region and three species for Eastern Mediterranean Region are recorded for the first time. Moreover, a total of fourty-five species are the first record for various provinces (8 for Adana, 4 for Balıkesir, 14 for İçel, 3 for Kahramanmaraş, 10 for Niğde, 6 for Osmaniye) in Turkey. Furthermore, about 15% of the examined taxa in the present work comprise of endemic taxa for Turkey.
