TL;DR: Modified systems of nomenclature based on holotrichous Gamasina are introduced and applied to setae on the dorsum of the idiosoma and on the venter of the opisthosoma.
Abstract: Generic and familial concepts of the Ascidae Voigts and Oudemans (= Blattisociidae Garman, Aceosejidae Baker and Wharton) are reviewed and modified from a world standpoint. The postembryonic developments of chaetotactic and external morphological features of the body and appendages are discussed. Twenty-two genera in three subfamilies are recognized, keyed, and defined: Arctoseius Thor, Iphidozercon Berlese, Xenoseius nov., and Zerconopsis Hull in the Arctoseiinae Evans; Cheiroseius Berlese and Platyseius Berlese in the Platyseiinae Evans; Aceodromus Muma, Antennoseius Berlese, Arctoseiodes Willmann, Asca Heyden, Blattisocius Keegan, Diseius nov., Gamasellodes Athias-Henriot, Hoploseius Berlese, Lasioseius Berlese, Leioseius Berlese, Melichares Hering, Neojordensia Evans, Proctolaelaps Berlese, Protogamasellus Karg, Rhinoseius Baker and Yunker, and Zercoseius Berlese in the Ascinae Voigts and Oudemans.Newly synonymized genera are Hyattella Krantz under Lasioseius, Mucroseius Lindquist and Orolaelaps DeLeon under Melichares, Garmaniella Westerboer under Proctolaelaps, and Tropicoseius Baker and Yunker under Rhinoseius. Genera removed from the Ascidae include Africoseius Krantz, Digamasellus Berlese, Laelaptoseius Womersley, and Zygoseius Berlese.Modified systems of nomenclature based on holotrichous Gamasina are introduced and applied to setae on the dorsum of the idiosoma and on the venter of the opisthosoma.

TL;DR: The generic and suprageneric taxa of Tarsonemidae, as known from the world fauna, are revised systematically and phylogenetically, based on a comprehensive assessment of morphology, ontogeny, and homology of tarsonemid structures, including their condition as found in other families of Heterostigmata.
Abstract: A critical historical review of previous classifications and other work on tarsonemid and related mites is presented. General information concerning tarsonemids is reviewed, including the following: geographical distribution, life history, sex determination, sex ratio, copulation, adult female reproductive capacity and longevity, dispersal, food and host preferences, economic importance, and natural enemies.The generic and suprageneric taxa of Tarsonemidae, as known from the world fauna, are revised systematically and phylogenetically, based on a comprehensive assessment of morphology, ontogeny, and homology of tarsonemid structures, including their condition as found in other families of Heterostigmata. The fundamental systems of setal notation developed by Grandjean for the body and appendages of acariform mites are applied, including use for the first time of his special terminology for tarsal setae among heterostigmatic mites.Character transformation series (polarities) for the great majority of characters used in classifying tarsonemid mites are presented for the first time. The out-group method of comparison was used to propose character state polarities, based on the cladistic methodology of Hennig. The transformation series hypothesized for each of 157 characters are numbered, diagrammed in detail, and summarized in tabular form, both for the families of Tarsonemina and Heterostigmata in general and for the genera of Tarsonemidae in particular.Based on the above character transformation series, a tentative phylogeny of the genera of Tarsonemidae is proposed and illustrated by dendrograms. Three subfamilies are recognized, with Pseudotarsonemoidinae new subfam.being the sister-group of [Tarsoneminae + Acarapinae]. Seven tribes are recognized: the sister-groups Pseudotarsonemoidini and Tarsonemellini new tribes in Pseudotarsonemoidinae; the sister-groups Acarapini and Coreitarsonemini in Acarapinae; and sister-groups Steneotarsonemini and Hemitarsonemini new tribes, which together form the sister-group of Tarsonemini, in Tarsoneminae. Similar sister-groupings are proposed for the genera within each tribe, with 31 genera (7 new) and 5 subgenera allotted as follows. Pseudotarsonemoidini: Ununguitarsonemus Beer & Nucifora, 1965; Pseudotarsonemoides Vitzthum, 1921; Polyphagotarsonemus Beer & Nucifora, 1965; Nasutitarsonemus Beer & Nucifora, 1965; and Tarsanonychus new genus. Tarsonemellini: Tarsonemella Hirst, 1923. Coreitarsonemini: Amcortarsonemus Fain, 1971; Asiocortarsonemus Fain, 1971; and Coreitarsonemus Fain, 1970. Acarapini: Acarapis Hirst, 1923. Hemitarsonemini: Hemitarsonemus Ewing, 1939; Eotarsonemus De Leon, 1966; and questionably Heterotarsonemus Smiley, 1969. Steneotarsonemini: Steneotarsonemus Beer, 1954 (including subgenera Parasteneotarsonemus Beer & Nucifora, 1965, new status; Mahunkacarus Vainshtein, 1979; and Neosteneotarsonemus Tseng & Lo, 1980, new status), Ogmotarsonemus new genus, Suskia new genus, Phytonemus new genus, Dendroptus Kramer, 1876, new status; and Acaronemus Lindquist & Smiley, 1978. Tarsonemini: Fungitarsonemus Cromroy, 1958; Rhynchotarsonemus Beer, 1954; Deleonia new genus, Ceratotarsonemus De Leon, 1956; Daidalotarsonemus De Leon, 1956; Iponemus Lindquist, 1969; Pseudotarsonemus new genus; Suctarsonemus Mahunka, 1974; Xenotarsonemus Beer, 1954; Neotarsonemoides Kaliszewski, 1984; and Tarsonemus Canestrini & Fanzago, 1876 (including subgenera Chaetotarsonemus Beer & Nucifora, 1965, new status; and Floridotarsonemus Attiah, 1970, new status). Tribal placement of Pseudacarapis new genus is uncertain, though it belongs in Tarsoneminae.New generic synonymies include the following: Neotarsonemus Smiley, 1967 objectively under Polyphagotarsonemus Beer & Nucifora, 1965; Parasteneotarsonemus Beer & Nucifora, 1965, and Neosteneotarsonemus Tseng & Lo, 1980 subjectively under, but subgenera of, Steneotarsonemus Beer, 1954; Praeacaronemus Kaliszewski & Magowski, 1985 subjectively under Acaronemus Lindquist & Smiley, 1978; Ditarsonemoides Kaliszewski, in prep. subjectively under Neotarsonemoides Kaliszewski, 1984; Lupotarsonemus Beer & Nucifora, 1965, Metatarsonemus Attiah, 1970, and Cheylotarsonemus Tseng & Lo, 1980 subjectively under Tarsonemus Canestrini & Fanzago, 1876; and Chaetotarsonemus Beer & Nucifora, 1965, and Floridotarsonemus Attiah, 1970 subjectively under, but subgenera of, Tarsonemus Canestrini & Fanzago, 1876. Newly designated nomina nuda are Punctatutarsonemus Nucifora, 1964, referred to Iponemus Lindquist, 1969, and Lupotarsonemus Beer & Nucifora, 1965, referred to Tarsonemus Canestrini & Fanzago, 1876.Descriptions are provided of the subfamily Tarsonemoidea and of all family-group taxa of Tarsonemidae. A key to the adult females, and to the adult males and larvae so far as they are known, together with diagnoses, detailed descriptions, and habitus figures, are presented for the genera and subgenera of Tarsonemidae. Definitions of each genus- and family-group taxon, based primarily on apomorphies, are also given in the section on phylogenetic relationships. Remarks on the distribution, habitats, habits, and other taxonomic and nomenclatorial aspects are given under each genus, followed by a world list of nominate species thought to belong to each genus, and indication of material examined. Descriptions of type-species, either new or inadequately described previously, are given for genera and subgenera as follows: Nasutitarsonemus brontispae Beer & Nucifora, 1965; Tarsanonychus emblematus n.sp.; Steneotarsonemus (Neosteneotarsonemus) arcticus n.sp.; Ogmotarsonemus erepsis n.sp.; Suskia mansoni n.sp.; Pseudotarsonemus eueides n.sp.; Neotarsonemoides adae Kaliszewski, 1984; Tarsonemus (Floridotarsonemus) scaber Attiah, 1970.Based on transformation series of the same characters mentioned above, a tentative phylogeny of Tarsonemidae and other families of Tarsonemina and Heterostigmata is proposed. A sister-grouping of Tarsonemidae and Podapolipidae is strongly supported apomorphically, with Pyemotoidea being the sister-group of Tarsonemoidea. Pygmephoroidea is strongly supported as the sister-group of [Pyemotoidea + Tarsonemoidea]. Of special note is a series of successive out-group relationships to [Pygmephoroidea + Pyemotoidea + Tarsonemoidea] of Trochometridiidae, then Dolichocybidae, then Heterocheylidae, and finally the Tarsocheylidae as the out-group of all other families of Heterostigmata. Each of the latter four families, therefore, warrants superfamilial status, with Trochometridiidae and Dolichocybidae being outside of Pygmephoroidea and Pyemotoidea, respectively. The Tarsonemina is strongly supported apomorphically as a subcohort. However, Heterocheyloidea appears to represent a sister-group to Tarsonemina rather than to Tarsocheyloidea, such that a grouping of Heterocheyloidea with Tarsocheyloidea, to form a subcohort Tarsocheylina, would be paraphyletic.
