摘要

One new genus and four new species of eriophyoid mites from Britain are described and illustrated: Novophytoptus acu-leatus n. sp. (Phytoptidae) from Juncus squarrosus L. (Juncaceae); Tegnacus unicornutus n. gen. & n. sp. (Eriophyidae) from Carpinus betulus L. (Betulaceae); Calacaruspusillus n. sp. (Eriophyidae) from Calluna vulgaris (L.) Hull (Ericaceae); and Brevulacus extensus n. sp. (Diptilomiopidae) from Quercus robur L. (Fagaceae). Digital micrographs are also provided for each new taxon. Furthermore, 19 eriophyoid species are confirmed or recorded in Britain for the first time: one species in the family Phytoptidae, Trisetacus ehmanni Keifer from Pinus sylvestris L. (Pinaceae); 13 species belonging in the family Eriophyidae, Abacarus acutatusSukhareva and Aceria eximia Sukhareva from Calamagrostis epigeios (L.) Roth (Poaceae), Acaricalus hydrophylli Keifer from Ilex aquifolium L. (Aquifoliaceae), Aceria exigua (Liro) from C. vulgaris, Acaricalus rubrifoliae Labanowski and Glyptacus fagineaeCarmona from Q. robur, Aculus cytisi Labanowski from Cytisus scoparius (L.) (Fabaceae), Anthocoptes transitionalis Hodgkiss from Acerpseudoplatanus L. (Sapindaceae), Calepitrimerus buxi Petanovic" from Buxus sempervirens L. (Buxaceae), Calepitrimerus crataegi Malandraki, Petanovid & Emmanouel from Crataegus monogyna Jacq. (Rosaceae), Neotegonotus fastigatus (Nalepa) from Acer campestre L. (Sapindaceae), Phyllocoptes abaenus Keifer from Prunus spinosa L., and Platyphytoptus sabinianae Keifer from Pinusnigra J.F. Arnold; five species belonging in the family Diptilomiopidae, Brevulacus reticulatus Manson from Q. robur and Quercus cerris L., Cheiracus ornatus (Farkas) from Fagus sylvatica L. (Fagaceae), Quadracus urticarius (Canestrini & Massalongo) fromUrtica dioica L. (Urticaceae), Rhinophytoptus bagdasariani Shevtchenko & Pogosova from Ulmus procera Salisb. (Ulmaceae), and Rhyncaphytoptus amplus Keifer from Acer pseudoplatanus L. Two species are also recorded here in Britain as incursions, Tumescoptes trachycarpi Keifer on Trachycarpus fortunei (Hook.) H. Wendl. (Are-caceae) from a commercial plant nursery site, and Aceria gilloglii on Pleioblastus distichus (Mitford) Nakai [=Arundinariapygmaea (Miq.) Asch. & Graebn. var. disticha (Mitford) C.S. Chao & Renvoize] (Poaceae) from a botanical garden. Collection details, distribution records and host symptoms are given for each species. The practice of publishing records solely identified from gall morphology and host association is also discussed.
