Ixodida

Belongs within: Parasitiformes.Contains: Haemaphysalis, Amblyomma, Hyalomma, Rhipicephalus, Dermacentor, Ixodes. The Ixodida, ticks, are a group of large mites parasitic on vertebrates. The chelicerae are used to pierce the host’s skin after which the tick anchors itself in place using the toothed hypostome (Keirans 2009). Ticks are divided between three families with most species belonging to the… Continue reading Ixodida

Haemaphysalis

Belongs within: Ixodida. Haemaphysalis is a genus of ticks feeding on birds and mammals that is most diverse in the Old World. Significant representatives include the New World H. leporispalustris, an important vector of spotted fever and tularemia (Keirans 2009). Characters (from Keirans 2009): Ornate; eyes absent; palpi short, with segment II as broad as… Continue reading Haemaphysalis

Dermacentor

Belongs within: Ixodida. Dermacentor, the wood ticks, is a cosmopolitan genus of ticks found on all continents except Australia and Antarctica. They include vectors of diseases such as Rocky Mountain spotted fever, Q fever and tularemia (Keirans 2009). The Dermacentor ticks Published 30 November 2021 Among the ticks of most concern to humans are species… Continue reading Dermacentor

Rhipicephalus

Belongs within: Ixodida. Rhipicephalus, the brown ticks, is a genus of ticks that are primarily parasitic on mammals. They are most diverse in Africa though the brown dog tick R. sanguineus is perhaps the world’s most widespread tick. Molecular analysis indicates that the cattle ticks of the subgenus Boophilus should also be classified within Rhipicephalus… Continue reading Rhipicephalus

Hyalomma

Belongs within: Ixodida. Hyalomma is a genus of large, highly active ticks found in Eurasia and Africa. They have rather long mouthparts and may cause significant wounds on their hosts (Keirans 2009). Characters (from Keirans 2009): Scutum inornate; eyes large, bulging upward from distinct, deep sockets. Palpi much longer than basis capituli, palpal segment II… Continue reading Hyalomma

Amblyomma

Belongs within: Ixodida. Amblyomma is a large genus of ticks including both large, brightly ornamented mammal parasites and smaller, less ornamented parasites of reptiles and amphibians (Keirans 2009). The genus in its current circumscription is supported by molecular analysis though no unique morphological synapomorphies are known. Species of Amblyomma possess a pentagonal basis capituli with… Continue reading Amblyomma

Ixodes (Ixodes)

Belongs within: Ixodes. Ixodes subgenus Ixodes is the group of ticks including the primary vectors of Lyme disease, caused by the spirochaete Borrelia burgdorferi. These include the Palaearctic species I. ricinus and I. persulcatus, and the Nearctic spescies I. pacificus and I. dammini (Filippova 1991). Members of this subgenus are distinguished by the absence of… Continue reading Ixodes (Ixodes)
