Type locality. England (without exact locality).
Type specimens. Types of the species described by Michael (1892) are in the Natural History Museum, London (fide Lundquist & Edler, 1979).
Type host. The common mole, Talpa europaea (L., 1758), in its nests.
Host range. Haemogamasus horridus is able to parasitise a wide range of rodents and insectivores (Zemskaya, 1973; Haitlinger, 1988), and no particular species of mammals can be regarded as its principal host.
Distribution. This species has been collected from Europe, the Near East, Kyrgyzstan, and South America (Evans & Till, 1966; Zemskaya, 1973; Casanueva et al., 1994; Cicek et al., 2008), though it is apparently absent in North America (Williams et al., 1978; Whitaker et al., 2007). The data on its presence in Asiatic Russia are very scant. Zemskaya (1973) mentioned it from Tomsk Region (Western Siberia), and this remains the only published record of Hg. horridus from Asiatic Russia. Also, this species is mentioned in the electronic catalogue of the collection of the Siberian Zoological Museum (Novosibirsk, Russia) as living in Western Siberia (http:// szmn.sbras.ru/Inverteb/ Gamasina.htm). Unfortunately, both sources quoted above contain no data about exact localities of this species in Siberia.
