Measurements. - Length: 158- 176 jim, width: 156- 168 um. Dorsal side (Fig. 1): Clypeus wider than any other dorsal segment, its margin narrow. Both pairs of clypeal setae straight, setae Cj longer than C2> but both pairs shorter than setae of D-H segments. Ratio of the other setae: pSi = ps 2 < dj ^ ft = hj =ps3<ei<h 2 . Setae fl and hj slightly dilate, their cilia longer than those of setae ej and hj. Ventral side (Fig. 2): Apodeme 2 weakly developed consisting of some arches, not reaching to lateral margin of anterior sternal plate. Lateral corner of sejugal margin well narrowed, straight. Surface of posterior sternal apodeme and ap. 4 characteristically roughened. Among epimeral. setae la much stronger than 2a, their cilia stronger than those of other setae. Setae 3a shorter than 3b and arising in front of latter. Setae 4a and 4b very long arranged in a transversal line, setae 4a (54 pm) reaching to vulva, 4b (90 /am) reaching to posterior margin of body. Legs: Claw of leg I (Fig. 4) small, its peduncle well separated. Setae d very long its tubercle longer than peduncle of claw. Solenidia CO j and (O2 very long, CO 3 longer than o>i. Setae dF phylliform, with serrate margin. Claws of legs II (Fig. 5) and III thick, their basal part conspicuously wide (Fig. 16). Dorsal spine of femur IV (Fig. 3) well developed. Tibiotarsus elongate (Fig. 12), more than twice as long as wide. Material examined: Holotypus (1146-HT-85): Hungary, Bükk Mts. , Garadna valley, litter from oak-forest, 15 Juni, 1982., leg. S. Mahunka, 2 paratypes from the same sample. Holotypus and 1 paratype (1146-PT-85) deposited in the Hungarian Natural History Museum, Budapest, 1 paratype in the Museum d'Histoire Naturelle Geneva. Remarks: The new species belongs to the Scutacarus tacensis group, which may be well characterized by the elongate tibiotarsus of leg IV, the very long setae 4a-4b (4a longer than half of 4b) and the length and position of setae pS!-pS3. This group consists of the following species: S. tacensis Mahunka, 1964 S. davadshamsi Mahunka, 1965 S. geomyl Mahunka, 19 7 7 S. strinatii Cooremann, 1959 The re-examination of the type of Scutacarus strinatii Cooremann, 1959 was also necessary, but the new species and the other species in this species goup are distinguished from it by the very short 3c setae in strinatii.
