Eriophyes pyri ( Pagenstecher, 1857)

( Fig. 3 C)

Type data. Pyrus communis L., pear ( Rosaceae ); type locality not originally stated by Pagenstecher (1857). Germany was presumed by Amrine and Stasny (1994) based on the working place of the author.

Relation to the host plant. The mites inhabit leaf blisters in summer and terminal buds in winter. Smooth pustules along the leaf vein, raised on both sides of the leaf, with their openings on the lamina undersurface; pustules yellowish green at the beginning, later turning red, purple or black at maturity; pustules more or less solid with mites located between the parenchymatic cells ( Keifer 1975).

Geographic distribution. Nearctic, Neotropical, Palaearctic.

New locality record for Iran. 10 females, 2 males and 4 nymphs from Sardrud (38°01'36"N, 46°09'35"E), 1,377 m above sea level, on P. communis , coll. P. Lotfollahi, 1 August 2011.

Previous provincial records from Iran. East Azerbaijan, West Azerbaijan, Fars, Esfahan, Guilan, Mazandaran, Hamadan and Tehran, from Amelanchier ovalis Medik. , Amelanchier vulgaris Moench , Cotoneaster fontanesii Spach , Cotoneaster nummularius Fisch. & C.A. Mey. , Cotoneaster integerrimus Medik. , P. communis , Pyrus ussuriensis Maxim. , Sorbus americana Marshall var. sitchensis (M. Roem.) Sudw. , Sorbus aria Crantz , Sorbus aucuparia L., Sorbus chamaemespilus (L.) Crantz, Sorbus torminalis (L.) Crantz ( Khanjani & Haddad 2006).

Remarks. This mite was collected from leaf blisters. Based on the large range of host plant species documented, a careful examination of E. pyri populations recorded on different plant hosts should be carried out, combining morphometric studies with biological and molecular data.
