Lipothrix lubbocki is moderately common in England although there are as yet no records from Ireland and Wales. It reaches 2.0 mm in length and is yellowish red in colour with dark patches. A characteristic feature of this species is the presence of numerous thick blunt setae on the body (Fig. 1).
     The fourth antennal segment (ant4) is divided into six subsegments (Fig. 2). The inner edge of the mucro is serrated whereas the outer edge is smooth (Fig. 3). The female sub-anal appendages (SAA) are not expanded at the tip. The empodium of the foot is longer than the claw and bears a prominent lamella and filament (Fig. 4).
