Echinonyssus blanchardi— Tenorio 1984: 263; Tenorio 1985: 3, figs 1–2.
Type locality: Europe, Alpine region.
Type series: MNHN. The lectotype was designated by Tenorio (1985).
Type host:Marmota marmota Linnaeus, 1758.
Host range: Marmots, including the Altai marmot, Marmota baibacina Kastschenko, 1899, and the bobak, M. bobac Müller, 1776.
Distribution: Europe and the southern part of North Asia (Senotrusova & Kapitonov 1970; Tenorio 1985; Mašán & Fend’a 2010). In Asiatic Russia, H. blanchardi has been recorded chiefly from the mountain parts of Western Siberia (Altai and Salair Mts.), where it parazitises the Altai marmots (Davydova & Nikolsky 1986). Koroleva (1977) mentioned a finding of this species in Novosibirsk Region.
Notes: A new subspecies name, H. blanchardi asiaticus Senotrusova & Kapitonov, 1970, was proposed for populations of this species inhabiting the central and eastern parts of Kazakhstan. According to Tenorio (1985), it is a nomen nudum as the new name appeared in figure captions but nowhere in the text. This subspecies name is absent from Senotrusova’s later monograph (Senotrusova 1987); possibly it means that the author rejected her own previous opinion and considered H. blanchardi as a monotypic species.
