This new species is characterized by the short interlamellar setae or absent; slightly fusiform sensillus; distinct notogastral setae; small and rounded area porosa postanalis （Ap）. A table for distinguishing the known species and new one in the genus is provided.展开更多

However, species response vis-A-vis these factors differs. For a better understanding of the phenomenon, we have conducted this study which consists of following the spatio-temporal evolution of two species of Oribatida （Scheloribates sp. and Galumna sp.）. The sites which have been the subject of this study, are situated in different bioclimatic zones presenting a very different climatic, edaphic, nutritional, and altitudinal characteristics. The variability of ecological factors showed that the behavior of two species differs. Indeed, Scheloribates sp. is present in all sites except in Biskra whereas Galumna sp. is present only in sites belonging to humid and sub humid bioclimatic zones. Moreover, Scheloribates sp. appears more tolerant of environmental changes while Galumna sp. is more stringent and its presence is marked only in the sites where ecological conditions are better. Thus, it can be noted that the spatial and temporal distribution of oribatid is not only conditioned solely by environmental factors but also by intrinsic factors specific to each species. The specific behavior of Galumna sp. and the tolerance of Scheloribates sp. are interesting and can be the subject of bioindicator species that can inform us about the changes that effect whether natural or anthropogenic environment.展开更多

Two new species of C. pianmaensis sp. nov. and C. gaoligongensis sp. nov., are described here, which are collected on moss and leaf litter from Yunnan Province, China. These two species can be distinguished from all known species of Cubachipteria by the absence of interlamellar setae. A key to the known species of Cubachipteria is given. All type materials are deposited in Guizhou University, Guiyang City, China （GUGC）.展开更多

The values of abundance, species richness, diversity and evenness were significantly larger in OT and ON than in CT, indicating that the abundance and diversity in organic farming fields were greater than those in conventional farming. The community structure of enchytraeid genera was different between OT and ON. Enchytraeus was the most abundant in OT, while Fridericia in ON. The abundance of oribatids in OT was similar to that in ON, while the species richness and diversity in the former were smaller. These results suggested that no-tillage practice under organic management might contribute to the improvement in quality of soil mesofauna.展开更多
