126 Eriophyes casuarinae Channabasavanna 1966: 46 .

Type host. Casuarina equisetifolia L. ( Casuarinaceae ).

Type locality. Hesarghatta , Bangalore, Mysore, Karnataka, India .

Relationship to host plant. Mites are found under bract-like scales on terminal shoots ( Channabasavanna 1966).

Report in Brazil. On “Campus Luiz de Queiroz, Universidade de São Paulo ”, Piracicaba (in this paper, specimens deposited at the mite collection in ESALQ, USP), São Paulo .

Remark. It is the first report of this species in Brazil. No visible symptoms.

Type host plant status. Exotic ornamental tree, suitable for forming forests and reforestation in saline soils, as well as for landscape use in squares and large gardens. It is widely cultivated in restingas and beaches of our coast ( Lorenzi & Souza 2001).

127 Eriophyes cyperi Channabasavanna, 1966: 50 .

Type host. Cyperus pangorei Rottb. (Cyperaceae) .

Type locality. Hesarghatta , Bangalore, Mysore, Karnataka, India .

Relationship to host plant. Under bracts in inflorescence ( Channabasavanna 1966). Vagrant on bases of upper leaf surface and under sheath bracts in inflorescences of Cyperus sp. ( Flechtmann 2004a) .

Host plant and localities reports in Brazil. On Cyperus sp. (Cyperaceae) : Parati (Caminho do Ouro, 10 km north of Parati) ( Flechtmann 2004a), Rio de Janeiro.

Remark. The Brazilian female specimens differ only slightly from the description and drawings given by Channabasavanna for Eriophyes cyperi : the prodorsal shield lines, apparently smooth in the Indian specimens, are granular in the Brazilian material; also, the basal one-third of the coverflap is smooth and with a slight indication of lateral short lines in Channabasavanna’s drawing, but the Brazilian material presents two pairs of curved, transverse granular lines ( Flechtmann 2004a).

Type host plant status. Exotic herb (Tropicos 2020).

Additional host plant status in Brazil. Cyperus sp. — native herb, not endemic, widely distributed in all biomes and regions ( Flora do Brasil 2020).

128 * Eriophyes cyperinus Flechtmann, 2004 a: 160 .

Type host. Cyperus sp. Vahl ( Cyperaceae ).

Type locality. Piracicaba (22°42’30”S, 47°38’00”W), São Paulo, Brazil .

Relationship to host plant. Vagrants on the upper leaf bases ( Flechtmann 2004a).

Remark. Only known from the type host/locality.

Type host plant status. Native herb, not endemic, widely distributed in all biomes and regions ( Flora do Brasil 2020) .

129 Eriophyes pyri ( Pagenstecher, 1857) : 46. ( Amrine & Stasny 1994: 207).

Previous assignment.

Eriophyes piri ( Pagenstecher, 1857)( Nalepa, 1889)

Synonyms.

Typhlodromus pyri Scheuten, 1857

Phytoptus pyri Nalepa, 1889

Phytoptus piri Nalepa, 1890

Phytoptus orientalis Fockeu, 1892

Eriophyes orientalis ( Fockeu, 1892)

Eriophyes sorbi Canestrini, 1892

Type host. Pyrus communis L. ( Rosaceae ).

Type locality. Heidelberg [?], Germany .

Hosts plants and localities in Brazil. On P. communis (Rosaceae) : locality not informed ( Hogetop, 1932), Rio Grande do Sul; locality not informed ( Paschoal 1971), São Paulo; Frei Rogério ( Flechtmann, 2004c), Santa Catarina; on Malus domestica Borkh. (Rosaceae) : Campinas ( Chiavegato et al. 1967), Jundiaí ( Chiavegato et al. 1967), Monte Alegre do Sul ( Chiavegato et al. 1967), Valinhos ( Chiavegato et al. 1967), São Paulo; locality not informed ( Paschoal 1971), Rio Grande do Sul.

Relationship to host plants. Two strains of E. pyri are known, the blister and bud strains. The first one induces blisters on young leaves; blisters appear on the under surface of developing foliage, the color is initially red or pinkish and becomes dark brown or black as the infestation develops. The bud strain has been reported much less frequently, but is potentially a much more serious pest. Mites causes extensive damage to fruit buds and abnormal drop of blossom and immature fruit. Fruits that develop from infested flowers are distorted and scabby ( Meyer 1981; Easterbrook 1996).

Remarks. Type species in the genus Eriophyes . In Brazil the bud strain is reported causing shortening of internodes, formation of rosettes due to the atrophy of the buds, decreased growth and dryness of the attacked branch ( Chiavegato et al. 1967).

Type host plant status. Exotic fruit tree, widely cultivated in the country, mainly in the Southern Plateau ( Lorenzi et al. 2006).

Additional host plant status in Brazil. M. domestica —exotic fruit tree, cultivated mostly in South and Southeast Regions ( Lorenzi et al. 2006).
