摘要
A new species of Lohmanniidae, Meristacarus pubescentius sp. nov., is described from soil and leaf litter of Hainan Province, South China. It can be distinguished from all other Meristacarus species by the following characters: anterior exobothridial setae thorn-like, shorter than the interlamellar setae by one-tenth, transverse bands S-2-S-4, S-9, and S-10 complete while S-5-S-8 are interrupted medially. The new species is most similar to M. douhereti Balogh & Balogh, 1983 in having setiform notogastral setae and the median setae shorter than the marginal setae, but differ from M. douhereti by the very short, thorn-like anterior exobothridial seta, heavily ciliated sensillus and notogastral seta e(1) half as long as e(2). A supplementary description of Mixacarus (Phyllolohmannia) foliifer (Golosova, 1984), a new record to the Chinese fauna, is given from the same locality. Keys to species of Meristacarus and Mixacarus (Phyllolohmannia) are presented.
