The mites especially oribatids are very important due to their immense contribution towards increase of soil fertility through decomposition of organic matter and also acing as biocontrol agent. These mites also act as vector of anoplocephaline cestodes causing discomfort to domestic animals. The mites belonging to Oribatei Inferiores, one of the two major divisions of Oribatida or Cryptostigmata, are also considered as a major contributor in the process of organic decomposition as they are present in soil and litter in enormous number. They are also sometimes acting as agricultural pest. This book is a consolidated account of all the species of Oribatei Inferiores (Acari: Cryptostigmata) so far known for India. It includes descriptions, illustrations, synonymies, distribution, taxonomic keys for identification of various taxonomic categories encompassing 170 species under 42 genera and 16 families. The volume also provides a general discussion on habitat, food habit, biology, general morphology of the oribatid groups, economic importance, methods for collection, preservation, mounting, rearing systematic position, etc. At the end, a long list of references and index are also appended.
