There are a large number of mite species that live on and with ants.
Polyrhachis lamellidens workers are attacked by spider mites that appear to specialise on ants. These mites show a strong preference to attach to the petiole as the majority of individuals have been observed in this position. The advantage of this placement is unclear, but it is likely the mites are either protected from removal by the ant or are attacking the soft tissue near the joint between the ant’s petiole and gaster.

Dos Santos Lopes et al. (2015) - Most Oplitidae are myrmecophilous or termitophilous (Hunter and Farrier 1975, 1976), with adults as the most commonly encountered instar on the ants. Available data suggest that host specificity in Oplitidae is quite high, with individual oplitid species usually associated with only one, or a few closely related, host species (Hunter and Farrier 1975, 1976; Campbell et al. 2013). Oplitis is found worldwide, but current understanding of local faunas varies widely among regions. For example, while the European fauna is fairly well studied, the Neotropical fauna is still relatively poorly known (Sellnick 1926, 1954, 1963; Zirngiebl-Nicol and Hirschmann 1973a, 1973b; Hirschmann 1975, 1991; Hiramatsu and Hirschmann 1983; Kontschán and Starý 2012).
A survey of mites on ants in the genus Neoponera from the state of Bahia, northeastern Brazil, revealed a new Oplitis species of the paradoxa-Gruppe (Hirschmann 1991), interpreted here as Oplitis s.s., which will be described for the adult instars. This species is associated with three closely related Neoponera species in the Apicalis complex (Wild 2005).
A total of 291 Oplitis specimens were recovered attached to ants. Five of these specimens, recovered from three different nests of N. verenae, were identified as O. camponoti (Hirschmann 1991). Most likely this is accidental, as O. camponoti is normally associated with ants in the genus Camponotus (Hirschmann 1991).

Da Silva et al. (2017) - The mite genus Petalomium Cross 1965 (Acari: Heterostigmatina: Neopygmephoridae) includes about 40 described species, most of them associated with ants (Hymenoptera: Formicidae) (Khaustov 2015). The papers referring to Petalomium in Neotropical region are Mahunka (1981), describing P. affinitum from Santa Lucia, West Indies, and Berghoff et al. (2009), reporting 2 unidentified species from Republic of Panama. The aim of this study is to describe a new species associated with workers of the poneromorph ant Neoponera verenae from southern Bahia, Northeastern Brazil. For purposes of comparison, a closely related species, Petalomium gottrauxi Mahunka 1977 is redescribed based on the paratype and specimens from the Crimean Peninsula.
Members of the genus Reticulolaelaps (Mesostigmata: Laelapidae) have been found in soil, litter, tree bark as well as in ant nests (Nemati et al., 2013; Joharchi & Babaeian, 2015; Joharchi et al., 2016), although they have never been found on ants themselves. Due to their cheliceral morphology, Joharchi and Babaeian (2015) speculated that Reticulolaelaps prey on small invertebrates within the ant's nests (Moraza, 2019).
