The mite family Laelapidae includes approximately 800 species of morphologically, ecologically and behav iorally dermanyssoid mites of Mesostigmata (Hallan, 2005). They inhabit soillitter habitats and the nests of vertebrates and arthropods as obligate and facultative parasites of vertebrates, insect paraphages, and free living predators that predatory laelapids tend to be vora cious, polyphagous predator they reproduce quickly and can be reared easily (Walter and Oliver, 1989;Gillespie and Quiring, 1990;Lesna et al., 1995). These make them biological control agent of pests in soil such as Hypoaspis aculeifer (Beaulieu, 2009). Resource explorations of po tentially important natural enemies are becoming more important after the Nagoya protocol of protecting the genetic resources. In Korea, 10 genera, 25 species are listed (NIBR, 2013).The classification of family Laelapidae is unstable with different concepts of genera and subgenera for ex ample, Evans and Till (1966), Van Aswegen and Loots (1970), Tenorio (1982) and Karg (1993). The subfamily Hypo aspidinae (Hypoaspididae of Karg, 1993) often are col lected in litter and soil substrates and those often in cluded, while other genera are routinely or occasionally encountered in the nests of mammals or arthropods or directly associated with insects (Evans and Till, 1966;1979;Hunter and Rosario, 1988;Karg, 1993). The sub family Melittiphidinae sensu Casanueva (1993) includes genera that have established close associations with ants and bees and they often appear in considerable numbers in host and hives (Lindquist et al., 2009). Adult of the melittiphidine tribe Varroini is now considered as family Varroidae (Casanueva, 1993). The Laelapinae includes a large number of genera that are primarily facultative nest parasites of rodents, although some have associa tion with bats or primates (Radovsky, 1967;1969;1985) (as occurs also in the subfamily Hirstionyssinae).This subfamily Hypoaspidinae is usually considered to comprise the genera Hypoaspis Canestrini, 1884 sens. lat.
