Description of a new species of Ixodes Latreille, 1795 (Acari: Ixodidae) and notes on I. spinae Arthur, 1958, parasites of the rock hyrax, Procavia capensis (Pallas) (Hyracoidea: Procaviidae) in South Africa.

Ixodes (Afrixodes) hyracis n. sp. (Acari: Ixodidae) is described based on females ex the rock hyrax, Procavia capensis (Pallas) (Hyracoidea: Procaviidae) from South Africa.

Identity of Ixodes ugandanus Neumann, 1906 (Acari: Ixodidae), reinstatement of I. ampullaceus Warburton, 1933 as a valid species and redescription of I. aulacodi Arthur, 1956, parasites of rodents and other animals in sub-Saharan Africa.

The identity of Ixodes (Afrixodes) ugandanus Neumann, 1906 (Acari: Ixodidae) is established and its male and female are redescribed based on specimens collected on rodents (Rodentia: Muridae, Thryonomyidae) in Ethiopia and Uganda. Lectotype of I. ugandanus is designated here.

Description of a new species of Ixodes Latreille, 1795 (Acari: Ixodidae), parasite of the Mexican spiny pocket mouse, Heteromys irroratus Gray (Rodentia: Heteromyidae) in Mexico.

Ixodes (Ixodes) zacateco n. sp. (Acari: Ixodidae) is described based on females ex the Mexican spiny pocket mouse, Heteromys irroratus Gray (Rodentia: Heteromyidae) from Mexico.

Are there 16 species of brown dog ticks? Phylogenies from 60 entire mitochondrial genomes and 162 cox1 sequences reveal 16 species-level clades in the Rhipicephalus (Rhipicephalus) sanguineus group☆☆.

The Rhipicephalus sanguineus group, the brown dog ticks, are cosmopolitan and doubtless the most important ticks of domestic dogs, clinically and economically. Despite four decades of taxonomic enquiry with nucleotide sequences and morphology, the taxonomy of the R. sanguineus group is confused, even chaotic.

Margaropus Karsch, 1879 is not closely related to Boophilus Curtice, 1891 (Acari: Ixodidae).

Margaropus Karsch, 1879 and Boophilus Curtice, 1891 have been thought to be sister-taxa for over 75 years since these ticks share features like circular spiracles, no festoons, no distinct grooves behind the anus and one-host life cycles. We inferred the first phylogeny with Margaropus from 4,218 bp of mitochondrial (cox 1, 12S) and nuclear DNA (ITS2, 18S rRNA). Margaropus is not the sister-group to Boophilus or even closely related to Boophilus, but rather Margaropus is either the sister-group to, or embedded in, the genus Rhipicephalus.
