Scutacarus darwishi sp.n. Measurements. - Length: 200-225 pm, width: 160-180 fim. Dorsal side (Fig. 18): Both pairs of clypeal setae straight and rigid, inner pair originating somewhat anteriorly to the outer one. Among the setae of segments D-H only small differences visible, setae e and f equal in length, h

2 shorter than hi. Segment Ps bearing three pairs of setae, PS3 minute, ps

2 longer, but only half as long as setae psj. Ventral side (Fig. 19): Apodemes weakly developed, ap. 2 thin, ap. 4 short. Among epimeral setae la much longer, thicker and more ciliated than setae 2a. Setae 3b much longer than 3a and 3c, between setae 4a and 4b the difference more than double, the latter reaching to posterior margin of body. Legs: Claw of leg I (Fig. 20) well developed. Seta d arising on a very long chitinons tooth. Solenidium io j slightly shorter than&j 2 , latter longer than chitinous tooth. Seta ldj" of leg II (Fig. 22) spiniform, smooth. Tarsus of leg IV (Fig. 21) bearing seven setae, setae Id.

' the longest of all. Material examined: Holotypus (946-HT-84): Hungary, Kiskunság National Park: Ócsa, 18.

III. 1978, leg. E. HÁMORI; 3 paratypes: Lakltelek: Tőserdő, 9.V.

1977, leg. L. TOTH. It was collected by Barber trap. Holotypus and 1 paratype (946-PT-84) deposited in the HNHM; 1 paratype: CAMZ; 1 paratype: MHNG. Remarks: On the ground of the dorsal and ventral chaetotaxy and the shape of leg IV the new species belongs to the relation of the "

Uneatus group". It is distinguished from the related species by the nearly equaly long notogastral setae. We dedicate the new species to Dr.E. DARWISH, husband of the •junior author, for his very extensive help in the collection of the examined material. Scutacarus regenfussl sp.n. Measurements. - Length: 275/jm, width: 156

/im. Dorsal side (Fig. 23): Clypeus small, not wider than segment D. With the exception of fj , h

2 and ps setae, all dorsal setae slightly dilated, fusiform. Setae ps

3 spiniform and smooth, all other well ciliated. No striking difference in length and shape present among c^ , c

2 , d», e^ and fj . Setae psj longer than ps

2 . Ventral side (Fig. 24): All apoedemes thin and weakly developed, ap. 4 short. Epimeral setae also thin, comparatively short and simple. Setae la the strongest, 4b the longest. Setae 3a not reaching Insertion of setae 4a, latter originating In front of 4b . Legs. Claw of leg I (Fig. 25) large, its peduncle thick. Basal tooth of seta d thick, though seta short. Solenidium 60 j the greatest of all, longer than the&J

2

. Tarsus of legs II (Fig. 27) and III with very large, modofied setae (Id,* ' ). Tiblotarsus of leg IV (Fig. 26) with six setae. Material examined: Holotypus (947-HT-83): Hungary, Kiskunság National Park, Fülöpháza, October 1982. Leg. A.M. ZAKI. It was collected on Salix cinerea bush. Holotypus and 7 paratypes (947-PT-84) deposited in the HNHM; 2 paratype: CAMZ; 1 paratype: MHNG. Remarks: This very characteristic species stands very far from all known Scutacarus species, due to the lanceolate dorsal setae, the chaetotaxy on legs II and IV un known In the related taxa it belongs to the "

kassall-pratensls group". We dedicate the new species to the once excellent acarologist, the late Dr. H. REGENFUSS. Scutacarus muscorum spiculifer ssp.n. Measurements. - Length: 196-210 /im, width: 170-190 /am. Dorsal and ventral chaetotaxy as shown in Figs 28-34. Material examined: Holotypus (944-HT-84): Hungary, Kiskunság National Park: Fülöpháza, III. 1982. leg. A. ZAKI. 5 paratype: from the same sample. Holotypus and 3 paratypes (944-PT-84) deposited In the HNHM; 1 paratype: CAMZ; 1 paratype: MHNG. Remarks: The new subspecies may only be distinguished with difficulty from the other subspecies (S. muscorum plumlger Mahunka, 1964) described from South America (! ). Some difference observable in the position of setae 3a-3b-3c and the length and ratio of setae ps and 4a, 4b and 4c. A further investigation on a longer series of both froms is needed.
