New for the fauna of Mongolia. Locality: As-110 (8). Bakerdania raeki (Mah., 1967) New locality: As-100 (2). Bakerdania tarsalis (HIRST, 1921) New localities: As-104 (2), As-108 (5), As-110 (3). Bakerdania tsogsonzhavi (MAH., 1969) New localities : As-56 (2), As-106 (5), As-110 (2). Microdispidae Brennandania stenops (MAH., 1969) New locality: As-99 (2). Seutacaridae Imparipes (A.) stillatus sp. n. Length: 186 u,, width: 163 p.. Dorsal side (Fig. 14) : Clypeus small, margins narrow, its hairs short, densely ciliate, inner pair situated slightly anteriorly to outer pair, its base incrassate. All other hysterosomatic hairs strong, rigid, dorsal ones longer than inner lumbal hairs, inner sacral longer than dorsal ones. Outer lumbal and outer sacral hairs longer than their inner mates. Ventral side (Fig. 15); Gnathosoma small. All hairs of anterior sternal plate thin, setae coxales I internae longest, setae coxales II externae shortest, of all setae. Apodeme 2 semicircular. Posterior sternal plate wide, its apodeme 4 transverse, long, extending almost to lateral margin of sternal plate. Outer praesternal pair of hairs arising orly slightly posteriorly to, and considerably longer than, inner one, reaching beyond points of origin of inner poststernal hairs. Base of this latter pair much thickened, guttiform, but terminally considerably elongated. Outer poststernal hairs arising far from one another, at base of legs IV. Outer pair of caudal hairs longest, median one shortest of all caudal setae. Legs: Tibiotarsus of leg I (Fig. 16) with a well developed claw, basis of hair / much elongated, bearing also hair k. Solenidion tf x thick, short, co 1 thin but longer. Joints of leg IV elongated (Fig. 17), rather resembling those of Imparipes (A.) minor KAR., 1959. Hair q a short but robust spine. Type-material: 1 ex. (Holotype: T-1192 p-69): As-100. Remarks: The incrassate humeral and poststernal hairs have, in the above distribution, been as yet unknown in its congeners. Imparipes (I.) boldi sp. n. Length: 167 p,, width: 150 p. Dorsal side (Fig. 18): Clypeal hairs short, originating along a common transverse line. Setae dorsales, setae lumbales internae, and setae sacrales internae lengthening in this order of sequence. Setae lumbales externae as long as their inner mates, while setae sacrales externae considerably longer than setae sacrales internae. All dorsal hairs ornamented with long cilia. Ventral side (Fig. 20) : Anterior sternal plate narrow, setae coxales I internae longest of all and also most densely ciliate. Setae coxales II externae weakly but discernibly squamose. Posterior sternal plate wide, its anterior corners strongly
