We investigated the Culicoides fauna in Turkey during the years 2016-2019 in the process of entomological surveillance for arboviral diseases. The entomological survey was conducted at 104 sampling stations in 51 provinces in Turkey during four consecutive years. There were approximately 450,000 specimens and 59 identified species collected during the surveillance. Ten species were newly recorded for Turkey: C. chiopterus, C. grisescens, C. paradoxalis, C. santonicus, C. poperinghensis, C. sergenti, C. tbilisicus, C. comosioculatus, C. haranti, and C. univittatus. Identification of C. chiopterus and C. grisescens was confirmed using species-specific PCR and DNA sequencing. With our recent findings, previous data were critically reviewed and updated, and the number of Culicoides species has been increased to 71 for Turkey. The presence of C. chiopterus has particular importance due to its potential vector status for bluetongue virus (BTV) and Schmallenberg virus (SBV). This study presents result of the first large-scale integrated faunistic survey on Culicoides species in Turkey.
