Apanaskevich & Horak (2008a) emphasized the difficulties involved in morphologically separating adults of Hyalomma albiparmatum , Hyalomma nitidum and Hyalomma truncatum , adding that it is not possible to differentiate their larvae and nymphs. There are several synonyms of Hyalomma truncatum ( Apanaskevich & Horak 2008a), but Hyalomma impressum transiens and Hyalomma transiens have been extensively used instead of Hyalomma truncatum .

Hyalomma truncatum was found in Bangladesh by Rahman & Mondal (1985), who believed that this tick was introduced with imported domestic animals but is not established in that country. There are several records of Hyalomma truncatum from Egypt, including Okely et al. (2021, 2022), who treated this tick as endemic in that country, although Apanaskevich & Horak (2008a) maintained that Egyptian specimens are mostly introduced, and Hyalomma truncatum is provisionally treated here as an Afrotropical species established south of the Sahara Desert. Farooqi et al. (2017), Adil et al. (2021) and other authors allegedly found this tick in Pakistan, but these records are treated here as probable misidentifications.

Sands et al. (2017a, b) presented molecular evidence indicating that more than one species may exist under the name Hyalomma truncatum , but Schulz et al. (2020) discount this, arguing that the former authors’ data are insufficient to sustain such an hypothesis.
