005 * Acalitus accolus Flechtmann, Amrine & Stasny, 1995a: 207 . (J.W. Amrine Jr., personal communication).

Previous assignment.

Acalitus accola Flechtmann, Amrine & Stasny, 1995a: 207 .

Type host. unidentified small Rubiaceae tree.

Type locality. Parque Nacional do Itatiaia , Itatiaia, Rio de Janeiro, Brazil .

Relationship to host plant. Infested leaves with pouch galls on the upper surface and erineum (composed of tangled filaments) on the lower surface. Since A. accola was found with another eriophyid mite, Distaceria ommatos Flechtmann, Amrine & Stasny, 1995a , it is not known which gall is caused by each mite species ( Flechtmann et al. 1995a).

Remarks. Only known from the type host/locality.

Type host plant status in Brazil. Although unidentified Rubiaceae , probably native since it was collected in preserved areas .

006 * Acalitus carbonis Navia & Flechtmann, 1998 a: 121 .

Type host. Sclerolobium paniculatum Vog. (Caesalpiniaceae) , presently referred as Tachigali vulgaris L.G. Silva & H. C. Lima ( Fabaceae ) ( Flora do Brasil 2020).

Type locality. Cavalcante , Goiás, Brazil .

Relationship to host plant. Collected from leaf erineum-galls in association with Aculops emblemus Navia & Flechtmann, 1998a . It could not be determined which species causes the galls.

Remark. Only known from the type host/locality.

Type host plant status in Brazil. Native tree, endemic, occurring in Amazônia , Caatinga and Cerrado biomes ( Flora do Brasil 2020) .

007 Acalitus gossypii ( Banks, 1904) : 56 ( Keifer 1965a: 3).

Previous genera assignments.

Eriophyes , Cecidophyes

Type host. Gossypium sp. (Malvaceae) .

Type locality. Montserrat, Lesser Antilles , British West Indies .

Additional reports in Brazil. On Gossypium hirsutum L. ( Malvaceae ): Cachoeira, Castro Alves and Jequié ( Bondar 1924), Bahia ; Pelotas ( Ronna 1934), Rio Grande do Sul; São Bento ( Hambleton & Sauer 1938), Pernambuco; on Gossypium barbadense L. ( Malvaceae ): Brasília ( Gonçalves et al. 2008) , Distrito Federal; Uberlândia (in this paper, specimens deposited at the mite collection at ESALQ, USP), Minas Gerais.

Relationship to host plants. Mites attack the flower buds and any parts arising from the buds may be infested. The leaves are contorted and crumpled or aborted and with short petioles. The flowers are covered with fine white hairs and the petals fail to open. Young plants show stunted, irregular growth and lack flowering branches. Mite feeding on the undersurface of the leaves cause chlorosis and whitish blisters ( Jeppson et al. 1975).

Type host plant status in Brazil. Tropical perennial shrubs, naturalized, extensively cultivated as fiber source ( Queironga et al. 2019) .

Additional host plant status in Brazil. G. barbadense — naturalized shrub/subshrub, occurring in Amazônia, Caatinga and Mata Atlântica biomes ( Flora do Brasil 2020); semi - domesticated cotton, cultivated in small crops ( Queironga et al. 2019); G. hirsutum — tropical perennial shrubs, naturalized, extensively cultivated as fiber source ( Queironga et al. 2019).

008 Acalitus orthomerus ( Keifer, 1951) : 94. ( Keifer 1965b: 15).

Previous assignment.

Aceria orthomera Keifer, 1951 .

Type host. Rubus vitifolius Cham. & Schlecht. (Rosaceae) , presently referred as Rubus ursinus Cham. & Schltdl. (Tropicos 2020) .

Type locality. Sacramento , California, USA .

Reports in Brazil. On Rubus sp. (hybrid berry) ( Rosaceae ): Experimental orchard of Embrapa Temperate Agriculture, Pelotas (31°40’39.9’’S, 52°26’16.4’’W) ( Trinidad et al. 2018), Rio Grande do Sul.

Relation to the host plants. Mites occur in the buds and at the petiole bases of the type host. No apparent damage to the vines has been noted ( Keifer 1951). In Rubus hybrids in Brazil, mites are found around the surface of the fruits and irregular maturity is observed among drupelets ( Trinidad et al. 2018).

Remark. Supplementary description in Trinidad et al. (2018: 1207).

Type host plant status in Brazil. Exotic shrub or vine, distributed through southern California into Mexico ( FEIS, 2020) .

Additional host plant status in Brazil. Rubus sp. —native herb, liana/scandent/vine, shrub, subshrub, not endemic, occurring in Amazônia, Caatinga, Cerrado, Mata Atlântica and Pampa biomes ( Bianchini 2020). Although some Rubus species are native to Brazil, most of hybrids cultivated in the country are originated from genetic material imported from the USA ( Antunes et al. 2014).

009 Acalitus simplex Flechtmann & Etienne, 2002: 10 .

Type host. Ruellia tuberosa L. ( Acanthaceae ).

Type locality. Clairange , Grand Bourg, Marie Galante / Guadeloupe .

Host and localities reports in Brazil. on Ruellia simplex C. Wright (Acanthaceae) : Brasilia ( Ventura et al. 2018) , Distrito Federal; Vitória (20°17’21”S, 40°17’30”W) ( Ventura et al. 2018), Espírito Santo; Santa Bárbara d’Oeste ( Ventura et al. 2018), São Paulo.

Relationship to the host plants. On type host plant, R. tuberosa , mites are vagrants on lower leaf surface ( Flechtmann & Etienne 2002); on R. simplex mites cause extensive whitish or silver color erineum and also unorganized growth of buds or flower buds (Rocha et al. submitted).

Type host plant status in Brazil. Exotic , cultivated as an ornamental .

Additional host plant status in Brazil. R. simplex — native subshrub, not endemic to Brazil, occurring in Cerrado, Mata Atlântica, Pampa and Pantanal biomes, widely cultivated as an ornamental ( Flora do Brasil 2020).

Relationship to host plant. Galls on lower leaf surface ( Flechtmann 1999a).

Remarks. Only known from the type host/locality.

Type host plant status in Brazil. Native shrub or tree, not endemic, widely distributed in all biomes and regions ( Machado et al. 2020) .
