(1987), Mašán & Fend’a (2010: 71).    Remarks. The genus was established by Berlese (1889)to include the single species,  Hg. hirsutusfrom the European mole ( Fig. 1). This species has not been found in Asiatic Russiaalthough numerous recordings of  Hg. hirsutusfrom the European part of the former USSRare known ( Nikulina, 2004). The most important taxonomic works on the genus are those by Vitzthum (1930), Bregetova (1949, 1956a), Keegan (1951), Evans & Till (1966), Allred (1969), Williams et al. (1978), Haitlinger (1988), and Lundquist (1990). The species of the genus were thought to inhabit all continents, except South America( Bregetova, 1956a; Williams et al., 1978; Lundquist, 1990), but later records of  Haemogamasusfrom Argentinaand Chilehave now been published ( Mosquera, 1988; Casanueva et al., 1994; Herrin & Sage, 2012). The genus includes about 60 species, 12 of which have been recorded in Europe (Mašán & Fend’a, 2010) and nearly 30 species in the former USSR(  Senotrusova, 1987;  Goncharova et al., 1991). Oneof these species,  Hg. pontiger(Berlese, 1904), is of almost cosmopolitan distribution, being recorded from the Old World, the Americas, Antarcticaand Australia(  Lundquist, 1990;  Halliday, 2011). Ecologically, most species of  Haemogamasusare parasites of small mammals and abundant in their hosts’ nests and shelters (  Balashov, 2009). Ingeneral, these mites are opportunistic parasites able to exploit a wide range of host species (  Bregetova, 1949); some of them were collected also from birds and birds’ nests (  Haitlinger, 1988; Gwaizdowicz et al., 2006). Stricthost specificity in the genus is rarely observed ( Bregetova& Nel’zina, 1952). Sometaxa (  Hg. pontiger) are regarded as predators (  Halliday, 2011), and their relationships with Micromammaliaare rather indirect. Therole of different  Haemogamasusspecies as vectors of viruses and other pathogenic microorganisms has been elucidated by many authors (  Zemskaya, 1973;  Yakimenko et al., 2000;  Valiente Moro et al., 2005;  Žákovská et al., 2008; Mi’tkova et al., 2015). 1977786296 USSR Russia Mi'tkova 4 5 South America Zakovska 3 4 1
