Hypogastrura purpurescens is a very common species found in a wide variety of localities including caves, organic matter and sewage filter beds. It is unique in possessing only two clavate tenant setae on the tibiotarsus of the third leg in two rows, one in row A and one in row B (Fig. 5) (tt1 has two clavate tenant setae in two rows and tt2 has three in two rows).
