A total of 3311 tick specimens were randomly collected from domestic animals including cattle, sheep, goats, horses, donkeys, and dogs from Lesotho districts namely, Berea, Butha-Buthe, Leribe, Mafeteng, Maseru, Mohale’s Hoek, Mokhotlong, Qacha’s Nek, Quthing and Thaba Tseka. Tick species were identified morpholog- ically and verified by amplification and sequencing of the CO1 and 18S rRNA genes. Nine species were identified under different genera namely, Haemaphysalis elliptica 0.1% (n = 2), Hyalomma rufipes 2.6% (n = 87), Hy. truncatum 1.2% (n = 41), Otobius megnini 13.6% (n = 451), Rhipicephalus appendiculatus 0.1% (n = 3), Rhipice- phalus decoloratus 9.3% (n = 308), Rhipicephalus evertsi evertsi 65.1% (n = 2156), Rhipicephalus glabroscutatum 1.3% (n = 43) and Rhipicephalus microplus 6.6% (n = 220). There was a significant difference at p = 6.2E-06 (χ2 = 1.923, df = 7) in the distribution of tick species and their abundance p = 0.04 (χ2 = 1.923, df = 7) from each population. The CO1 and 18S rRNA sequences matched the morphological determinations on the NCBI database and clustered with relevant species on the phylogenetic tree. Genetic analysis of CO1 and 18S rRNA provided very strong support for monophyly of the Rhipicephalinae and Ornithodorinae complexes. Both CO1 and 18S rRNA are useful genetic markers for the specific and generic characterization of tick species in Lesotho and elsewhere. This is the first scientific publication of tick species occurring in Lesotho.
