Further information on morphological characteristics of Macrocheles mammifer Berlese (Mesostigmata: Eviphidoidea: Macrochelidae)

The Macrochelidae Vitzthum, 1930 is a very large group of cosmopolitan free-living predatory mites, many of which are found in diverse habitats (Krantz 1998; Halliday 2000; Ma??n 2003). This family comprised nearly 450 known species and 15 genera in 2003 (Ma??n 2003), while Emberson (2010) has raised some subgenera to genus level and considered about 470 accepted described species for the family. The genus Macrocheles Latreille, 1829 is the largest genus of this family with about 400 species distributed all over the world. Its species are found in various microhabitats related to decaying organic material, in associations with insects and in nests of small terrestrial mammals and birds (Krantz 1998; Ma??n 2003).
