Klompen, JSH 1991. Phylogenetic relationships in the mite family Sarcoptzdae (Acari: Astigmata). Misc. Publ. Univ. Michigan, Mus. Zool., 180: 1-155, 265figs. A phylogenetic analysis of relationships among the 117 recognizable species of the mite family Sarcoptidae Murray, 1877 is carried out based on 215 morphological and ontogenetic characters. The putative sister group of the Sarcoptidae, the family Rhyncoptidae, and more distantly related families in the Sarcoptoidea (Psoroptidae, Lobalgidae, Myocoptidae) are used as outgroups. All of these taxa are obligate, permanent ectoparasites of mammals. Due to the large quantity of missing data and the overall size of the matrix, the analysis is carried out in parts. Initial analyses, including only those taxa for which the quantity of missing data is low, are used to establish a hypothesis of relationships among the larger subgroups. Relationships within each subgroup are analyzed separately. The subgroup analyses are rooted using hypothetical ancestors which are constructed based on the results of the initial analyses.

A new classification of the Sarcoptidae is proposed based on the results of the systematic analysis. T he family is divided in three subfamilies, the Diabolicoptinae Fain & Domrow, 1974 (2 genera, 3 species), Sarcoptinae Murray, 1877 (4 genera, 8 species) and Teinocoptinae Fain, 1959 (9 genera, 106 species). These groupings include two newly described genera and 18 newly described species. Within the Sarcoptinae, the genus Pithesarcoptes Fain, 1965 is synonymized with Prosarcoptes Lavoipierre, 1960 and the subgenus T7ixacarus (caviacoptes) Fain et al., 1972 with Trixucaw (ss) Sellnick, 1944. At the species level, Prosarcoptes faini Lavoipierre, 1970 is synonymized with P. pitheci (Philippe, 1948). The Teinocoptinae includes the formerly recognized families Teinocoptidae Fain, 1959 and Bakerocoptidae Fain, 1962, as well as the subfamily Notoedrinae Fain, 1968 (Sarcoptidae). Within this lineage the genus Bakerocoptes Fain, 1962 is synonymized with Nycteridocoptes Oudemans, 1898, the subgenus Chirnyssozdes (Carollicoptes) Fain & Lukoschus, 1971 with Chirnyssoides (ss) Fain, 1959, and the genera Chirnyssus Fain, 1959 and Suncicoptes Fain & Lukoschus, 1976, and subgenera Notoedres (Neonotoedres) Fain, 1963, N.(Metanotoedres) Fain, 1959, and N. uanmotoedres) Fain, 1965 with Notoedres (ss) Railliet, 1893. At the species level, Notoedres dohanyi Klompen et al., 1983 is synonymized with N. tadaridne Fain, 1959, N. schoutedeni hyatti Fain, 1963 with N. chiropteralis (Trouessart, 1896), and N. douglmi Lavoipierre, 1964 with N. centrifera Jansen, 1963. New combinations include Tychosarcoptes amphipterinon (Klompen et al., 1984) and Chirobia brevior (Fain et a]., 1982), both transferred from Teinocoptes; Teinocoptes harfqionycteris (Klompen & OConnor, 1987), transferred from Chirobia; Notoedres (Bakeracarus) plecoti Fain, 1959, transferred from N.(Notoedres); N.(B.) eptesicw (Fain & Lukoschus, 1971), N.(B.) corynorhini (Fain, 1961), and N.(B.) anisothk (Fain & Lukoschus, 1975), formerly subspecies of N.(B.) hionycteris (Boyd & Bernstein, 1950). Data on ecology, pathology and host associations are summarized for all species of the family, and identification keys to all species are included.
