Geographic distribution of the hard ticks (Acari: Ixodida: Ixodidae) of the world by countries and territories Author Guglielmone, Alberto A. 0000-0001-5430-2889 guglielmone.alberto@inta.gob.ar Author Nava, Santiago 0000-0001-7791-4239 nava.santiago@inta.gob.ar Author Robbins, Richard G. 0000-0003-2443-5271 robbinsrg@si.edu text Zootaxa 2023 2023-03-07 5251 1 1 274 http://dx.doi.org/10.11646/zootaxa.5251.1.1 journal article 235222 10.11646/zootaxa.5251.1.1 43227427-a867-4744-9e4c-2b2302524890 1175-5326 7704190 3326BF76-A2FB-4244-BA4C-D0AF81F55637 154. Ixodes moschiferi Nemenz, 1968 . Palearctic: 1) China (north), 2) Nepal (north and central) ( Nemenz 1968 , Teng 1982a , Chen et al. 2010 , Pun et al. 2018 ). Some Chinese records of Ixodes moschiferi have been published under the name Ixodes rangtangensis , a synonym of Ixodes moschiferi in Teng (1986) , Camicas et al. (1998) and Guglielmone et al. (2009) , but treated as a valid species in Horak et al. (2002) . Camicas et al. (1998) regarded Ixodes moschiferi as an Oriental species. Clifford et al. (1975a) stated that the type specimen of Ixodes moschiferi , collected in Thâmi, Solokhumbu District, Nepal ( Nemenz 1968 , Pun et al. 2018 ), was found on a host at an altitude of 1000 m , but Nemenz (1968) clearly indicated that it was collected at an altitude of 4000 m . Teng (1982a) listed Rangtang (northwestern Sichuan), Tibet and Qinghai as collection localities of Ixodes moschiferi and its synonym, Ixodes rangtangensis Teng, 1973 . All these localities are regarded as lying within the Palearctic Region; consequently, we follow Guglielmone et al. (2014, 2020) in treating Ixodes moschiferi as a Palearctic species.
