A. Skoracka ; 12 females . Female ( 1 specimen ): ( 195 ) long; chelicerae ( 22 ) long, shield ( 43 ) long, ( 50 ) wide, dorsal tubercles ( 26 ) apart, directing setae to the rear. Opisthosoma of ( 61 ) dorsal annuli and ( 74 ) ventral annuli. Genitalia ( 16 ) long, ( 24 ) wide; genital setae ( 35 ) long, tubercles ( 15 ) apart. Male: ( 150 ) long; shield ( 37 ) long, dorsal setae ( 25 ) long. Genitalia ( 20 ) wide; genital setae ( 15 ) long, tubercles ( 15 ) apart. In descriptions of four new records only the characteristics that differ from those given in the original descriptions are presented. Because Nalepa’s diagnosis ( 1896 ) is not complete, specimens of A. hystrix were compared with the description made by Keifer ( 1944 ) . Nevertheless, some characteristics of specimens of this species, described from many countries, are similar to those of Mongolian specimens ( Meyer 1989 ; Proeseler 1972 ; Roivainen 1947 ; 1951 ; Sukhareva 1992 ). Besides, we have found Novophytoptus stipae Keifer, 1962 on Agropyron cristatum (L.) P. Beauv. and Phytoptus niloticus Abou­Awad, 1981 on D. caespitosa , but only one female of both species.
