Provincial and regional distribution of the members of tribe Cerambycini Latreille (Cerambycidae: Cerambycinae) in Turkey with new records, and known and new host plants
Abstract : The paper presents updated provincial and regional distributions in Turkey of the members of Cerambycini tribe with their host plants. As a result, a total of 12 species-group taxa (10 species and 2 non-nominal subspecies) of two subgenera belonging to one genus of Cerambycini tribe were determined, evaluated and updated with their distributions in Turkey and their all host plants. In terms of range of provincial and modern regional distribution in Turkey, C. cerdo acuminatus with 37 provinces and 7 regions and C. dux with 33 provinces and 7 regions are strikingly prevailing. Similarly, in terms of number of recorded classical regions in Turkey, C. cerdo acuminatus and C. dux each with 18 concepts are strikingly prevailing. Moreover, according to the present study, the distribution range of 7 species-group taxa is expanded by determining new provincial and regional records for them. Among them, C. welensii centurio is new to Turkey, and therefore Gaziantep and Hatay provinces. Also, C. heinzianus is recorded for the first time from Erzurum, Osmaniye and Tunceli provinces, and therefore Mediterranean region of Turkey. In addition, C. carinatus for Muğla province, C. cerdo acuminatus for Bitlis, Çorum and Mardin provinces, C. nodulosus nodulosus for Amasya, Hatay and Tunceli provinces, C. welensii welensii for Afyonkarahisar and Sakarya provinces, and C. scopolii nitidus for Adana province are new records. With the present study, host plants of a total of 10 of 12 species-group taxa are determined. Among them, 9 of 12 species-group taxa are polyphagous in deciduous trees, while only C. heinzianus seems to be monophagous in deciduous trees of Fagaceae (Quercus spp.) now. Host plants of the remaining two species-group taxa as C. kodymi and C. welensii centurio are still unknown. In addition, the host range of four species-group taxa is expanded by determining new host plants for them. Corylaceae (Ostrya carpinifolia), Fagaceae (Quercus conferta), and Platanaceae (Platanus orientalis) for C. cerdo acuminatus Motschulsky; Corylaceae (Corylus avellana), Punicaceae (Punica granatum), and Rosaceae (Prunus amygdaloides and Cerasus avium) for C. dux; Rosaceae (Cerasus avium) for C. miles, and also Fagaceae (Quercus cerris) and Rosaceae (Malus sylvestris) for C. nodulosus nodulosus are detected for the first time as host plants of these taxa. Moreover, in terms of the number of host plant families and species, C. scopolii scopolii with 29 plant species-group taxa of 11 different plant families, C. cerdo acuminatus with 28 plant species-group taxa of 9 different plant families, and C. cerdo cerdo with 24 plant species-group taxa of 7 different plant families are strikingly prevailing. Among the 12 species-group taxa of Turkish Cerambycini, only C. heinzianus is endemic to Turkey. Thus, the endemism ratio of Turkish Cerambycini is low with 8.33 percent.
