ly applying apomorphic characteristics like the shape of the sensillus or some setae, or the number of claws, the number and position of octotactic orqans when describing new genera or even higher categories. In my present work I tried to avoid these tipping places by carefully evaluating the used features, and partly Oy deferring to described species based on such features or working out such too elaborate systems . My opinion was summed up in the previous part discussing the features and their value in taxu^ematics. I regarded it highly important to use in my subsequent system the characteristics found mainly in the anogenital region. Thus , I do not consider appropriate to divide the old two large families, although certain features would suggest and support this. Thus, e.g. in the family Oribotritiidae the position presence or absence of setae before the suture kag of genital setae, or that of bothridial squama, or the modification of thl chaetotaxy of legs guard-coupled setae beside the solenidia on the 2nd or the 4th tibia the presence or absence of solenidia on the genu of leg IV , but, of course the same applies to the rather complicated group of the superfamily PhthiracariFig. 3.
