The members of tribe Graciliini Mulsant (Cerambycidae: Cerambycinae) in Turkey with their distribution and host plants
Abstract : The paper presents distributions in Turkey of the members of Graciliini tribe with their host plants. As a result, a total of 5 species-group taxa (4 species + 1 non-nominal subspecies) of 4 genera were determined and evaluated with their distributions in Turkey and their all host plants for Turkish Graciliini. In terms of range of provincial and modern regional distribution in Turkey, P. fasciata with 14 provinces and 4 regions is strikingly prevailing. A. gracilis gracilis with 6 provinces and 2 regions and H. starcki starcki with 4 provinces and one region follow it. Similarly, in terms of number of recorded classical regions in Turkey, P. fasciata with 10 concepts is strikingly prevailing. A. gracilis gracilis with 6 concepts and G. minuta with 3 concepts follow it. Moreover, the distribution range of 2 of 6 species-group taxa in Turkey is expanded by determining new provincial records for them. Thus, A. gracilis diversicornis is recorded for the first time from Konya province, while P. fasciata is recorded for the first time from Hatay province. With the present study, host plants of all species-group taxa are determined. Apparently, A. gracilis gracilis, G. minuta, H. starcki starcki and P. fasciata are polyphagous in deciduous trees, and also coniferous trees. On the contrary of this, A. gracilis diversicornis seems to be monophagous in deciduous trees, while H. starcki ivani seems to be monophagous in coniferous trees. In addition, the host range of 4 of 6 species-group taxa in Turkey is expanded by determining new host plants for them. Thus, Fagaceae (Quercus sp.) for A. gracilis diversicornis, Lauraceae (Laurus nobilis) and Rosaceae (Crataegus sp., Malus sp.) for A. gracilis gracilis, Corylaceae (Corylus avellana) and Juglandaceae (Juglans regia) for H. starcki starcki, and Rhamnaceae (Paliurus spina-christi) for P. fasciata are the first detection as host plants of these taxa with the present study. Finally, Turkish Graciliini has two endemic species-group taxa as A. gracilis diversicornis and Hybometopia starcki ivani. Thus, the endemism ratio of Turkish Graciliini is 33.33%.
