Taxonomic uncertainty as to the identities of Hyalomma (Euhyalomma) scupense Schulze, 1919 and Hyalomma detritum Schulze, 1919 has existed for nearly 85 years. The chief criterion used to consider these taxa as separate species has been an ecological feature, namely that H. scupense is a one-host tick while H. detritum is a two-host species. Morphologically they are identical. To date no comprehensive taxonomic study has been done on all parasitic stages of the two species. Here the decision to grant priority status to H. scupense and to synonymise H. detritum with H. scupense is defended. The adults and immature stages of H. scupense are illustrated and redescribed. The morphological characteristics that separate the males, females, nymphs and larvae from those of other Hyalomma species are discussed for each developmental stage. Data on hosts, geographic distribution and disease relationships are provided.
