This paper is a systematic revision of the genus Hirstionyssus Fonseca, 1948, of the Nearctic region. On the basis of numerical taxonomic analyses and the distribution of qualitative characters, 25 taxospecies, placed in 6 rather well denned host groups, are formally recognized. Four new taxospecies are described: H. perognathi n. sp., H. blarinae n. sp., H. paraffinis n. sp., and H. neocynomys n. sp. Five previously described taxospecies are relegated to synonymy: H. palustris Allred & Beck, 1966; H. punctatus Allred & Beck, 1966; H. invaginatus Allred & Beck, 1966; H. angustus Allred & Beck, 1966; and H. tarsalis Allred & Beck, 1966. Two subgenera are recognized: Mephitonyssus, new subgenus, to include the single taxospecies of the carnivore host group, H. staffordi Strandtmann & Hunt, 1951; and Hirstionyssus s. str. to include the other 24 taxospecies of the geomyid, heteromyid, insectivore, sciurid, and muroid host groups—H. femuralis Allred, 1957; H. geomydis (Keegan, 1946); H. thomomys Allred & Beck, 1966; H. longichelae Allred & Beck, 1966; H. hilli (Jameson, 1950); H. perognathi n. sp.; H. incomptis (Eads & Hightower, 1952); H. triacanthus (Jameson, 1950); H. blarinae n. sp.; H. talpae Zemskaya, 1955 (=H. arcuatus of authors); H. affinis (Jameson, 1950); H. paraffinis n. sp.; H. occidentalis (Ewing, 1923); H. eulamiae Allred & Beck, 1966; H. cynomys (Radford, 1941); H. utahensis Allred & Beck, 1966; H. latiscutatus (de Meillon & Lavoipierre, 1944) (=H. musculi of authors); H. neocynomys n. sp.; H. torus Allred & Beck, 1966; H. obsoletus Jameson, 1950; H. isabellinus (Oudemans, 1913); H. breviseta Strandtmann & Morlan, 1953; H. neotomae (Eads & Hightower, 1951); and H. bisetosus Allred, 1957. The subfamily Hirstionyssinae, the genus Hirstionyssus, and the 2 proposed subgenera are reviewed and diagnosed; an identification key to the females of the genus is constructed; and each recognized taxospecies is given a complete taxonomic treatment with synonymy, diagnosis, illustrations, and collection records.
