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

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

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.
