Remarks.

There are six slides of this species in the Berlese Acaroteca (190/15-17, 194/18, 210/37-38). These slides contain at least 12 specimens, including those of Ameroseius molliculus (nomen nudum) and Ameroseius dubitatus , all collected in Italy (Firenze and Padova), and not labelled as „tipico”. Without doubt, those from Firenze belong to the original type specimens of Berlese. They are mostly in bad condition to be examined. However, an examination of the specimens showed specific features also detected in well preserved specimens available for study from Slovakia and other regions of Europe.

Based on an examination of the type specimens, Ameroseius stramenis Karg, 1976 and Lasioseius gracilis Halbert, 1923 are considered new junior synonyms of Kleemannia delicata (Berlese, 1918). The two former species were briefly described in their original descriptions. Halbert (1923) did not inform the number of setae on the dorsum, but his illustration shows 26-27 setae, lacking z6. Karg (1971a, 1993) slightly modified Halbert’s illustration to show 27 setal pairs. I could detect the full complement of 29 pairs of setae in type series of both, Ameroseius delicatus and Ameroseius gracilis . The re-description and illustrations given by Westerboer and Bernhard (1963) for Ameroseius delicatus do not require serious amendment, except for the shape of ventrianal shield. This shield is usually not so regularly subcircular as illustrated, but almost truncate and slightly concave anteriorly. In A. stramenis , Karg’s (1976) interpretation of curved epistome seems to be apparently atypical for the genus, but I could not confirm it in the single available type specimen loaned from Berlin Collection (the epistome is obscure and not observable). In addition, the female of A. stramenis was illustrated by Karg as lacking metapodal platelets and one pair of opisthogastric setae (JV4), although both structures were reliably detected in an axamination of the holotype. Examination of numerous specimens from various mueum collections showed that Kleemannia delicata is fairly common in buildings in Europe and has often been misidentified, mainly as Kleemannia plumigera .
