Redefining () species complex in Greece focusing on the mitogenome of .

species complex, referred to as (), is distributed globally with some species distributed in specific regions and others spread globally. In Greece, () in dogs, and and in livestock, have been repeatedly reported however only based on morphological identification. Recently, there has been a great effort to accurately identify the species belonging to the species complex, using modern molecular tools and describe their spatial distribution. The aim of this study was to expand the studies on the molecular characterisation of species of the () complex in the Mediterranean region, by molecularly characterising ticks collected from various locations and host species in Greece. Results confirm the presence of , , , and . The complete mitochondrial genome of (approx. 15 kb) from sheep ( = 3) in Greece was sequenced and matched to sequences and morphological data from the type-material from Israel. Additionally, the mitogenome of from goats ( = 2) in Greece was sequenced. This study provides a molecular reference for , a tick species distributed in the Eastern Mediterranean region.
