New eriophyoid mites (Acari: Prostigmata: Eriophyoidea) in Britain: one new genus, four new species, 19 new records and two incursions Author Pye, Daniel R. L. text Zootaxa 2012 3578 43 68 journal article 10.5281/zenodo.208898 c5ed4058-99a4-4727-8aa6-96c045bb70e7 1175-5326 208898 Aceria gilloglii Keifer 1963 Type host and locality. Host originally listed as Sasa pygmaea E. G. Camus ( Keifer 1963 ) , and later listed as Arundinaria pygmaea (Miq.) Asch. & Graebn ( Baker et al. 1996 ) (Poaceae) , USA , California, Los Angeles. Distribution. England (recorded here as an incursion on a non-native host planted in 1992), Georgia [from Sasa veitchii (Carrière) Rehder and Pleioblastus distichus (Mitford) Nakai (Poaceae) ] ( Sukhareva 1994 ) and USA , California (op. cit.), Relation to host. Vagrant on the under surface of the leaves, concentrated at the base, and also found between the leaf sheaths. Can apparently cause a slight "witches’ broom" effect when present in large numbers ( Keifer 1963 ). Collection details. England , Surrey, Kew, Royal Botanical Gardens (RBG), high numbers on a bamboo tentatively named as Pleioblastus distichus (Mitford) Nakai (Chris Stapleton, formerly of Kew, RBG, personal communication 2012) [Kew accession number 1993–1136, named Arundinaria pygmaea (Miq.) Asch. & Graebn. var. disticha (Mitford) C. S. Chao & Renvoize ], collected by Sara Redstone (Plant Health & Quarantine Officer, Kew, RBG), 27.vii.2010 . Additional remarks. The mites were found on a non-native bamboo planted in Kew gardens in 1992. Aceria gilloglii is therefore recorded here in Britain as an incursion. However, bamboo plants are a popular ornamental in private and botanical gardens, but this eriophyoid species has so far not been recorded elsewhere in Britain , although more intensive and targeted surveys may reveal otherwise.
