Abstract

The supplementary descriptions of two species of Oribatodes (Oribatida, Cepheusidae), O. mirabilis Banks, 1895 and O. reticulatus (Sitnikova, 1979), are presented, based on adults collected from the U.S.A. and Panama, respectively. The deutonymphal and tritonymphal instars of O. mirabilis and the deutonymphal instar of O. reticulatus are described; this is the first data on juveniles of the genus. The revised generic diagnosis and an identification key to the known representatives of Oribatodes are provided. The taxonomic status of the related genus Reticulocepheus Vasiliu & Călugăr, 1977 is discussed, resulting in the following new taxonomic proposals: Oribatodes Banks, 1895 (=Reticulocepheus Vasiliu & Călugăr, 1977 syn. nov.); O. areolatus (Sitnikova, 1979) comb. nov.; O. decoui (Vasiliu & Călugăr, 1977) comb. nov.; O. grandis (Sitnikova, 1979) comb. nov.; O. mirabiloides (Jacot, 1938) comb. nov.; and O. reticulatus (Sitnikova, 1979) comb. nov. Comparative characteristics of juveniles of the different genera of Cepheusidae are given based on our own data and available literature sources.

对口螨属 Oribatodes（Acari，Oribatida，Cepheusidae）知识的贡献，附两个物种的补充描述和幼体数据

根据分别从美国和巴拿马收集到的成虫，对两种 Oribatodes（Oribatida, Cepheusidae），O. mirabilis Banks, 1895 和 O. reticulatus（Sitnikova, 1979）进行了补充描述。描述了 O. mirabilis 的去鳞茎和三鳞茎蜕期以及 O. reticulatus 的去鳞茎蜕期；这是关于该属幼虫的第一个数据。本文提供了经修订的 Oribatodes 属性诊断和已知代表种的识别钥匙。讨论了相关属 Reticulocepheus Vasiliu & Călugăr, 1977 的分类地位，提出了以下新的分类建议：Oribatodes Banks, 1895 (=Reticulocepheus Vasiliu & Călugăr, 1977 syn. nov.); O. areolatus (Sitnikova, 1979) comb.根据我们自己的数据和现有的文献资料，给出了 Cepheusidae 不同属的幼体比较特征。
