Euscorpius thracicus sp. n. from eastern Bulgaria is described, fully complemented with color photographs of both live and preserved specimens, as well as their habitats. This species is described based on morphology and the cytochrome oxidase I (COI) DNA barcoding marker. In addition to the analyses of external morphology and hemispermatophore, we also describe the karyotype of E. thracicus sp. n. (2n=92).
