(Ixodoidea: Ixodidae), a species of the Rhipicephalus sanguineus group in southwestern Europe 2024 Access copy available to the general public Unrestricted We describe all the life stages of Rhipicephalus hibericus n. sp., provide the types, and present molecular support for a new species of the Rhipicephalus sanguineus sensu lato group, present in southwestern Europe, that has been historically confused with Rhipicephalus turanicus Pomerantzev, 1940. A new name is proposed for this taxon because it was impossible to ascribe to types of already described species in the group, deposited for more than 100 years in natural history institutions. The males have a dorsum showing deep and coarse punctations (absent in Rhipicephalus sanguineus sensu stricto) and adanal plates with large punctations (absent in R. sanguineus s.s.); the tail of the spiracular plate is as wide as the closest festoon (half the width in R. sanguineus s.s.). Females have large punctations in dorsal fields, a wide spiracular plate, and a “V” shaped genital opening; such a combination of characters cannot be found in other species of the group. Immatures are described from specimens collected on hosts (Rodentia and Eulipotyphla). Both larvae and nymphs are markedly smaller than R. sanguineus s.s. Nymphs display long, backward-projected auriculae; larvae are almost half the size of R. sanguineus s.s. The new species can hybridize with R. sanguineus s.s. in laboratory colonies producing an unfertile F2, laying brown and dry eggs that did not hatch. Phylogenetic analysis of partial coxI gene sequences placed R. hibericus in a well-supported clade with other sequences of R. sanguineus s.l. from Portugal, as a sister clade of R. sanguineus s.s. The new species does not belong to the R. turanicus group of species. Both 12S and 16S partial gene sequences were not as precise in the correct phylogenetic placement of R. hibericus, in part probably due to the existence of erroneously identified sequences in GenBank©. This description, together with the previous reinstatement of Rhipicephalus secundus and Rhipicephalus rutilus, and the description of the neotypes of R. sanguineus s.s. should help researchers to adequately identify their collections. Our findings demonstrate that R. turanicus is absent in southwestern Europe. Old collections should be re-examined to provide the actual range of the new species. info:eu-repo/grantAgreement/ES/DGA/LMP90_21 info:eu-repo/semantics/openAccess by https://creativecommons.org/licenses/by/4.0/deed.es 3.4 2024 PARASITOLOGY 6 / 47 = 0.128 2024 Q1 T1 INFECTIOUS DISEASES 39 / 137 = 0.285 2024 Q2 T1 MICROBIOLOGY 71 / 163 = 0.436 2024 Q2 T2 1.034 2024 Infectious Diseases 2024 Q1 Parasitology 2024 Q1 Insect Science 2024 Q1 Microbiology 2024 Q2 7.1 2024 info:eu-repo/semantics/article info:eu-repo/semantics/publishedVersion Rodríguez-Pastor, Ruth Universidad de Zaragoza (orcid)0000-0001-8435-6386 Estrada-Peña, Agustín Universidad de Zaragoza (orcid)0000-0001-7483-046X 1009 773 Universidad de Zaragoza Dpto.
