A new Siculobata species (Acari: Oribatida: Scheloribatidae) from Argentina

This article provides a taxonomic description of Siculobata talarica sp. nov. collected from native forest soil of Buenos Aires, Argentina. This new species was compared to its conspecifics: Siculobata sicula and Siculobata malabarica, respectively. After a status and affinity revision among Siculobata, Metaleius, Paraleius, Vesiculobates and Floribates, the taxonomic concept of Siculobata is reconsidered and a more accurate diagnosis of its genus is proposed. http://zoobank.org/urn:lsid:zoobank.org:pub:549CA8BD-3716-43ED-BACC-4634C6F19FB3

Revision of Physobates (Acari, Oribatida, Tegoribatidae) and redescription of Physobates spinipes Hammer, 1962 with comments on tegoribatid genera.

Description of a new species of Paralamellobates (Acari, Oribatida) from Argentina, with a revision of the genus

ABSTRACT The aim of this paper is to propose a new species of Paralamellobates, P. argentinensis sp. nov., on the basis of adult stages and to redescribe Lamellobates quadricornis Pérez-Iñigo & Baggio, 1985. Based on a morphological comparison between Paralamellobates species and L. quadricornis, Paralamellobates quadricornis stat. nov., is proposed. http://www.zoobank.org/urn:lsid:zoobank.org:pub:AFB88025-DEEC-4A3D-AD99-57DEB503533C
