Abstract
Bulgarian carabid fauna is relatively well studied but there are still many species and regions in the country lacking enough research. The present paper aims at complementing the data about the distribution of the carabids from the subfamily Trechinae, containing many diverse, interesting and endemic species. Currently, 55 species of Trechini, 118 species of Bembidiini (incl. Tachyina), and 13 species of Pogonini are known in Bulgaria. This study gives new information and new records on 41 Trechinae species and 17 zoogeographical regions and subregions. The material was collected in the period from 1979 to 2020 through different sampling methods. There are 20 species recorded for the first time in different regions. Two species are reported for the second time in the regions where they were currently collected. Seventeen species haven’t been reported for more than 20 years from the Boboshevo-Simitli valley, Sandanski-Petrich valley, Rila Mts., Pirin Mts., and Slavyanka Mts., and are now discovered there again.
