^ A New Species and Five New Records of Ameroseiidae from Taiwan (Acari: Mesostigmata) Chyi-Chen Ho1*, Li-Ming Ma2, Shun-Cheng Wang3, and Lucia Liu Severinghaus4 1Retired scholar, [email protected] 2Chinese Base for Control and Prevention of Plague and Brucellosis, Baicheng, Jilin, China 3Department of Environmental Engineering and Management, Chaoyang University of Technology, Taichung County 41349, Taiwan 4Biodiversity Research Center, Academia Sinica, Taipei City 11529, Taiwan ABSTRACT Six species of Ameroseiidae (Berlese, 1919) are reported from Taiwan, including one new species and five new records. Afrocypholaelaps analicullus sp. nov. and Neocypholaelaps ewae Haitlinger, 1987 were collected from Apis merlifera L. The otherfour species, Ameroseius magnisetosa Ishikawa, 1972, Ameroseius lidiae Bregetova, 1977, Ameroseius matsudai Ishikawa, and Ameroseius vietnamensis Micherdzinski, 1965 were collected from soil. Ameroseiid mites from Taiwan, China, Japan, and Vietnam are listed to check the commonly distributed species. A key to the world species ofthe genus Afrocypholaelaps is given. Key words: Ameroseiidae, Afrocypholaelaps, Neocypholaelaps, Ameroseius, Taiwan Introduction plumosus (Oudemans), 1902 and Ameroseius plumigera Oudemans, 1930 Mites of the family Ameroseiidae from stored grains (Tjying, 1972), and (Berlese, 1919) were collected from store Neocypholaelaps indica Evans, 1963 from products, soil, decomposing organic matter, honeybee (Lo and Chao,1975).
