The community of mites (Acari) in the galleries of the spider Macrothele calpeiana (Araneae: Macrothelidae) in southern Spain

A total of 87 mite specimens from 16 burrows of the spider Macrothele calpeiana were studied in the southern part of Spain (Mediterranean region). Of these specimens, 60 were found in the spider webs, while 27 specimens, all belonging to Androlaelaps pilosus Baker, 1991, were found on the spiders themselves. The maximum number of mites found on the body of a single spider was eight, all adult females. Among the 19 species of mites found in the spider webs, including non-nominal ones, it is worth noting the presence of adult individuals of Erythracarus sp. and immature individuals of Fessonia sp. Some aspects of A. pilosus are discussed.
