Microtegeus khaustovi sp. nov. is similar to Microtegeus variabilis Mahunka, 1988 (Africa, Tanzania) and Microtegeus rugosus Mahunka, 1982 (Africa, Ethiopia), but differs from the former species by body size, number of prodorsal tubercles, length of notogastral setae c, and morphology of the notogaster; from the latter species it differs by morphology of lamellar setae, the number of prodorsal tubercles, and morphology of the notogaster.
