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

Pneumolaelaps

Belongs within: Laelapidae. Pneumolaelaps is a genus of laelapid mites found in the nests of bumblebees (Evans & Till 1979). Breath of the hunter The mites of the family Laelapidae are an ecologically diverse bunch. The earliest members of the family were probably free-living micro-predators, a lifestyle many maintain to this day, but many laelapids… Continue reading Pneumolaelaps

Parasitus

Belongs within: Parasitidae. Parasitus is a diverse genus of soil-living predatory mites. Despite their name, they are not parasites; the name originated from a misinterpretation of the behaviour of the phoretic deuteronymphs. Species are characterised by differentiation of the dorsal setae z5 from j5 and j6, with z5 usually being stout and setose (Evans &… Continue reading Parasitus

Haemogamasus

Belongs within: Laelapidae. Haemogamasus is a genus of nest-dwelling mites characterised by two or three denticles in each of the anterior rows of hypognathal denticles. Females have small, subovate metapodal shields and the opisthogenital shield is narrow (Evans & Till 1979). Members of the genus vary in habits from free-living scavengers to obligatory haematophages. <==Haemogamasus… Continue reading Haemogamasus

Parasitiformes

Belongs within: Euchelicerata.Contains: Mesostigmata, Ixodida. The Parasitiformes are a group of usually well-sclerotised mites, many of which are predatory or otherwise feeders on animal matter (scavengers or parasites). They are characterised by having the respiratory openings at the side of the body, close to the hind pairs of legs. Four pairs of dorsolateral stigmata are… Continue reading Parasitiformes

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
