New and Little Known Species of Oribatid Mites of the Genera Arthrodamaeus and Fuscozetes (Arachnida: Acari: Oribatida) from Mongolia

Abstract

A new species of gymnodamaeid mite, Arthrodamaeus mongolicus sp. nov. from Eastern Mongolia, is described. In addition, two known species of ceratozetid mites, Fuscozetes fuscipes (C. L. Koch, 1844) and F. tatricus Seniczak, 1993 are recorded for the first time in the fauna of Mongolia, and are re-described based on specimens from northern and eastern parts of the country. Arthrodamaeus mongolicus sp. nov. is easily distinguishable from all known species of the genus by the well developed tubercles on the anterior part of the notogaster.
