Additions to the knowledge of the oribatid mite genus Kalyptrazetes (Acari, Oribatida, Microzetidae)

Sergey G. Ermilov, Stefan Friedrich


A new species of microzetid oribatid mites of the genus Kalyptrazetes is described from upper soil and leaf litter in the primary evergreen lowland rainforest of Amazonian Peru. Kalyptrazetes bifurcatus Ermilov sp. nov. differs from other representatives of the genus by the morphology of rostral and centroventral epimeral setae and anterior parts of lamellae, the length of some notogastral, epimeral and genital setae, and the absence of an X-structure in the epimeral region. The main generic traits and an identification key to known species of Kalyptrazetes are provided.
