rank. During this work it became evident that the subfamily degree (proposed already by numerous authors,but not yet fixed) of Karschie

11idae

,treated for a long time as a family,is justified; furthermore, that Diplatyidae, more or less treated also as a family, may be inserted in the system also only as a subfamily. The arolium, present or absent among the claws and indicating also a significant physiological, i.e.ethological difference in the species, was, in all parts of the order and in all families, of subfamily rank; accordingly, I elevated the Map.l. Distribution of Pygidloranidae species of the genus Challia

, which differs sharply also zoo— geographically from the Anataellnae, to subfamily rank. In the present study I carried out subf
