Abstract
Seven species of eriophyoid mites previously described on bamboo plants in Thailand by Chandrapatya and Boczek are redescribed and/or reassigned. Phaicus is described as a new genus with Tegolopus [sic] bambusae ChannaBasavanna, 1966 designated as the type species and Abacarus panticis Keifer, 1977 and Aculodes ventricosae Chandrapatya, 1998 as synonyms. Aculus asperi (Chandrapatya and Boczek, 2002) is reassigned to Abacarus and redescribed. Abacarus klaengensis is a new name to replace Abacarus bambusae (Boczek, 1998) which is a junior homonym of Abacarus bambusae Kuang and Zhuo, 1987. Knorella blumeanae Xue and Zhang, 2009 is emended from Knorella blumcanae Xue and Zhang, 2009 due to misspelling of host plant. Neocatarhinus namtai is a new name to replace Neocatarhinus bambusae (Boczek, 1998), new combination,which is a junior homonym of Neocatarhinus bambusae Kuang and Hong, 1990. Kolacarus bambusae Boczek, 1998 and Knorella thailandica Hong, 1996, are redescribed. Males were described when found. Host lists and collecting data are corrected and new host plants with distribution have been added.
