description: <i>Eriophyes bromusi</i> Shi <i>et</i> Skoracka sp. nov. <i>Description</i> <i>Female</i> (Figs. 10­15) (holotype and 10 paratypes): 243 (186­295) long, 72 (70­77) wide; body wormlike. Gnathosoma 24 (24­28) long, antapical seta <i>d</i> 5 (4­5) long. Chelicerae 23 (20­23) long, almost straight. Prodorsal shield 41 (41­45) long, 60 (60­68) wide, subrhomboid in shape and smooth, with lobe weakly expressed; dorsal tubercles <i>sc</i> setae ahead of rear shield margin, 22 (18­22) apart, scapular setae <i>sc</i> 13 (11­14) long, directed up and centrad. Leg I 43 (40­46) long, tibia 11 (10­11) long with seta <i>l’</i> 6 (5­6) long; tarsus 10 (10­12) long; solenidion 9 (9­10) long, unknobbed; empodium 10 (9­10) long 4 ­rayed. Leg II 40 (39­41) long; tibia 7 (7­9) long; tarsus 9 (9­11) long; solenidion 9 (9­10) long, unknobbed; empodium 10 (9­10) long. Coxae smooth; sternum 10 (9­10) long. First forecoxal tubercles <i>1 b</i> 11 (11­13) apart, setae 8 (7­10) long; second tubercles <i>1a</i> 7 (6­8) apart, setae 40 (30­49) long; hindcoxal tubercles <i>2a</i> 25 (25­30) apart, setae 55 (43­66) long. Opisthosoma of 59 (57­61) smooth dorsal annuli and 65 (62­67) ventral annuli, only the last 4­5 annuli with several ventral microstriate. Lateral setae <i>c 2</i> 35 (30­36) long, on ventral annulus 11 (10­11); first ventral setae <i>d</i> 35 (32­37) long, on ventral annulus 24 (22­25); second ventral setae <i>e</i> 16 (14­17) long, on ventral annulus 41 (37­42); third ventral setae <i>f</i> 36 (34­38) long, on 6 th (5 th­ 6 th) annulus from the rear. Accessory <i>h</i> setae 4 (4­5) long. Female genitalia between ventral annuli 4 (3­4) and 5 (4­5), 19 (15­20) long and 27 (26­28) wide; coverflap smooth; <i>3 a</i> setae 18 (11­19) long, tubercles 17 (16­18) apart. <i>Male</i> (Fig. 16) (1 specimen): (205) long; prodorsal shield (41) long, with obscure lines; median on rear half of shield, admedians almost complete, short submedians between dorsal tubercles and admedians; sides of shield granular; coxae ornamented with dots. Opisthosoma of (55) dorsal and (70) ventral annuli, all microtuberculated. Genitalia (25) wide; <i>3 a</i> setae (14) long, tubercles (19) apart. <i>Nymph, larva</i>: not studied <i>Etymology</i>: the specific name is derived from host plant generic name. <i>Host plant</i>: <i>Bromus inermis</i> Leyss. (Poaceae). <i>Relation to host plant</i>: the mite causes galls on the plant leaves. <i>Type locality</i>: Mongolia, Arkhangay Aymag, near Tsetserleg locality, valley near larch and birch forest; 15.07.2000; leg. A. Skoracka. <i>Material examined</i>: holotype female, 10 female paratypes, 1 male allotype. <i>Differential diagnosis</i> The new species is close to <i>Eriophyes cyperi</i> (Channabasavanna, 1966), but it can be distinguished on the basis of differences in having smooth prodorsal shield, coxae, opisthosomal annuli and genital coverflap. In addition, the new species inhabits galls whilst <i>E. cyperi</i> lives underneath sheathing bracts on inflorescences. Since the male has microtuberculated annuli, obscure shield pattern and ornamented coxae, those females may be deutogynes that differ somehow from protogynes.
