The genus Hyalomma Koch, 1844. X. redescription of all parasitic stages of H. (Euhyalomma) scupense Schulze, 1919 (= H. detritum Schulze) (Acari: Ixodidae) and notes on its biology

摘要

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