Dermacentor silvarum Olenev, 1931a , but see note below. A Palearctic species in Guglielmone et al. (2014) but Zhang, G. et al. (2019) include the Oriental Region within the range of this tick, whose adults are usually found on Artiodactyla : Bovidae , Cervidae and Suidae , and Perissodactyla : Equidae ; larvae and nymphs are commonly recovered from Erinaceomorpha : Erinaceidae , Lagomorpha : Leporidae , and Rodentia (several families). All parasitic stages have been collected from Leporidae . Adults and nymphs have been recovered from Bovidae and Rodentia : Sciuridae ; adults have also been taken from Carnivora : Felidae ; immature stages have been found on Galliformes : Phasianidae , Passeriformes (several families), and Squamata : Lacertidae ; additionally, there are several records, presumably of immature stages, from Aves and Mammalia (Guglielmone et al. 2014, Shao et al. 2019). Dermacentor silvarum is a very frequent parasite of humans.

The study of Olenev (1931c) was published in December 1931 ; therefore, it is quite probable that the first description of Dermacentor silvarum is indeed that in Olenev (1931a) . Filippova (1997) does not recognize the description of the male of Dermacentor silvarum in Olenev (1931a , c), but this is treated as valid here. See also Dermacentor marginatus for a discussion of the problems attending identification of species in the Dermacentor marginatus group, to which Dermacentor silvarum belongs. Several redescriptions of Dermacentor silvarum published before the study of Pomerantzev (1950) , apart from those of Olenev (1931a , c), are not included in the above lists. Filippova (1997) does not recognize descriptions of the larva and nymph of Dermacentor silvarum published prior to the study of Filippova and Panova (1985) .
