Synopsis of the ticks of Algeria with new hosts and localities records

Ticks are obligate hematophagous arthropods with a world-wide distribution that are extremely important not only in terms of human and animal health but also economically. In Algeria, information on tick species is scarce. A systematic literature review was performed using online databases. The information extracted from the databases was was supplemented by information from an original study. Ticks were collected from various hosts and by flagging from January 2018 to December 2019. To date, in Algeria a total of 36 valid tick species belonging to two families have been recorded: (1) family Argasidae, with three Argas species and nine Ornithodoros species recorded; and (ii) family Ixodidae, with one Dermacentor species, three Haemaphysalis species, 10 Hyalomma species, four Ixodes species and six Rhipicephalus species recorded. The geographical distribution for each species was determined and listed. Eight new tick-host associations were recorded: four for Ixodes inopinatus sensu Estrada-Peéa et al. 2014, one for Rhipicephalus bursa, one for R. turanicus, one for Hyalomma marginatum and one for Hy. lusitanicum. To our best knowledge, this study is the first to report the presence of I. inopinatus sensu Estrada-Peéa et al. 2014 in Algeria. We also report here for the first time all tick species (Argasidae and Ixodidae) known to be present in Algeria. This article represents a tool for students and scientists who work in the field of ticks and provides important new data on the distribution of ticks in Algeria.
