Two new species of Papillacarus (Acari, Oribatida, Lohmanniidae) from China

Two new species of Lohmanniidae, Papillacarus (Papillacarus) internus sp. nov. from soil in Hainan Province, South China and Papillacarus (Vepracarus) hexagonus sp. nov. from rotten tree and soil in Chongqing City, Southwest China are described and illustrated. Papillacarus (P.) internus sp. nov. is most similar to Papillacarus (P.) lienhardi (Mahunka, 1997), however, it can be distinguished from the latter by the following characters: 29-30 pairs of additional neotrichal setae, seta c(1) shorter than c(2), all genital setae setiform and smooth. Papillacarus (V.) hexagonus sp. nov. is most similar to Papillacarus (V.) gueyeae (Perez-Inigo, 1989), however, it can be distinguished from the latter by the following characters: 38 pairs of additional neotrichal setae, 7 pairs of subcapitula setae, epimeral formula 9-4-3-4.
