Cerci and caudat part of subes andriat scierite very shori Fig. l 2) but with sonae long though thinsetae. Male sui stylus Fig. P) Shoin and emerging in an acute angle frona epandrium. Its short and weali cerci visibie on majori ty of males without genitalia preparation. This species is new to Hungary and to the Palaearctic Regio n. However. Iihin k that A. neoleuco ora could be a recent introduction to Europe since I didnot finii any specimens in old collections. The specimens in Hungary were found with in a circle of c. J V km radius. Since the ratio of the specimens of this speciesto leuco orti specimens is only l io lo. much more collecting is needed to bellerassess iis distribution.
