Icius subinermis is a species of jumping spider from the Mediterranean region.[1]
The two sexes have different coloration.[2]
Icius subinermis favors moist habitats, for example near streams or on moist meadows. It builds a silken retreat in infructescences of rushes or under rocks near rivers or creeks. It will retreat there when the weather is unfavorable.[2]
Although it is originally restricted to the western Mediterranean region, it has been occasionally found in greenhouses, for example in Cologne, Germany[2] in 1995. Recently, it has been found in the center of Ljubljana, Slovenia, and there are records from Switzerland and Italy.[3] An introduced North American population in Philadelphia, Pennsylvania, has been described.[4]
