S. plicatus n. sp. belongs to a group of Nearctic species related by similarities in the general shape of the anal plate, subsimilar shape and length of the pygidial setae a 1, a 2 and a 3 and antennal globulus with a strikingly high number of bracts: S. californianus Remy, S. fratuelis Remy, S. canadensis Scheller and S. boreus Scheller. The first is widely distributed, known from NE Siberia (Scheller 1986), California (Remy 1958), British Columbia (Scheller 1984) and the southern Appalachians. The other three have, as far as we know now, restricted ranges. Thus S. boreus Scheller is known only from Alaska (Scheller 1986), S. fratuelis Remy only from Tennessee (Remy 1958) and S. canadensis Scheller only from British Columbia (Scheller 1984). The new species can be distinguished from these species particularly by the shape of the styli of the pygidial tergum (thin and pointed, not more or less thick and blunt) and by the shape of the anal plate (posteriorly directed submedian branches parallel and very close to each other, not diverging). Similarities can be traced in the direction of the two Alaskan species S. longipes Scheller and S. longitarsus Scheller (Scheller 1986) but to a lesser degree. Derivation of name. From the Latin plicatus = fold (referring to the longitudinal folds of the anal plate). Description. Length. (0.89–) 0.99 mm. Head (Fig. 12). Tergal setae pubescent, median and submedian setae clavate, lateral and sublateral ones cylindrical, blunt, a 3 in 2nd row and l -group setae tapering pointed.

U. Scheller, E.Bernard, I. Stocks. Type material. Holotype: ad. 9(3), data as above. Paratypes: 3 ad. 9(Ƥ), 2 subad. 8(Ƥ), 1 juv. 6, 1 juv. 5, 2 juv. 3, Tennessee, Sevier Co., above Laurel Falls, in soil under large poplars (Lirodendron tulipifera), 11 November 2004, leg. W. Reynolds & E. Gileh.— 11 specimens. FIGURES 21–28.

Scale a: 24; b: 21, 25–27; c: 22, 23, 28. Diagnosis. Though this species has only one pair of setae on the pygidial sternum, b 1, and thus has to be placed in Donzelotauropus, it shows many similarities with a species in Stylopauropus earlier described from Great Smoky Mountains, Stylopauropus sulcatoidus Scheller (Scheller & Bernard, 2005). They resemble each other in the shape of the antennal globulus g, the bothriotricha, the general plan of the anal plate and the shape of the posterior part of the pygidial tergum and its setae. However, besides the presence of the b 1 D. dividuus is easily distinguished from S. sulcatoidus by the proportion q/s, 0.9, not 0.5 and the shape of the posterior part of the anal plate, incision deep U-shaped and appendages curved inwards and distinctly pubescent, not incision shallow, broadly Vshaped and appendages straight, faintly pubescent.

Paratype: 1 subad. 8 (&female;), same data as holotype. Described below. Type specimens deposited in the Zoological Museum, University of Lund, Sweden. Diagnosis. The new species belongs to a group of species characterized by a short anal plate with two posterior appendages, short pygidial setae a 1 and st and very long setae a 2 and a 3. It may be closest to A. maoriorum Remy (Remy, 1956), a wide ranging species in the southern hemisphere (known from Australia, New Zealand, New Caledonia and Chile) but known also from Sabah in the Malaysian part of Borneo. The two species are very alike but can be distinguished by many obvious dissimilarities: the shape of the antennal globulus g, stalk short and wide in A. maoriorum, distinctly thin in A. circulus; the shape of the bothriotricha T 3, axes increasing in width from the base and outwards, then being cylindrical, pubescence short, straight, oblique, not decreasing in width outwards and with long branched pubescence hairs arranged in whorls; the shape of the anal plate, with lateral corners, not circular; the posterior appendages of the anal plate appendages almost parallel, not diverging; and the size of the median lobe of the posterior margin of the pygidial sternum, small, not large. Derivation of name. From the Latin circulus = circle, referring to the shape of the anal plate. Description. Length. 0.47 (- 0.65) mm. Head (Fig. 1).

F 1 as long as t, F 2 and F 3 0.5 and 0.9 of the length of s respectively. Distal part of flagella not studied. Globulus g proportionally large, 1.7 times as long as its greatest diameter; ≈ 11 bracts; capsule longer than wide. Diameter of g 1.7 times as long as its greatest diameter and 1.1 times as long as the greatest diameter of t. Antennae glabrous. Trunk (Fig. 22). Collum segment not available for study. Seta on tergites as setae of the head. Two transversal rows, 4 + 4 setae on tergite I,? 4 + 6 on II and III, 6 + 6 on IV and V, 4 + 2 on VI. Submedian posterior setae on VI (Fig. 22) cylindrical, striate, blunt, curved inwards, 0.6 of interdistance and 1.6 times as long as pygidial setae a 1. Bothriotricha (Figs 23–24). Relative lengths: T 1 = 100, T 2 = T 3 = 108, T 4 = 137, T 5 = 167. Axes simple, straight, in all but T 3 very thin, with erect pubescence in whirls on T 1 (Fig. 23), T 2 and T 4. T 3 (Fig. 24) with thickened axes, particularly in distal halves and with very short pubescence of simple hairs, partly arranged in whirls. T 5 with shortest pubescence, on distal part oblique. Legs (Figs 25–27). Seta on coxa (Fig. 25) and trochanter (Fig. 26) of leg 9 furcate, both branches cylindrical, blunt, striate, secondary branch distinctly shorter than primary one. Tarsus of leg 9 (Fig. 27) tapering, glabrous, 3.2 times as long as its greatest diameter, setae cylindrical, blunt, annulated, proximal seta 0.2 of the length of tarsus and 1.3 times as long as distal seta. Pygidium (Figs 28–29). Tergum. Posterior margin between insertion areas of setae a 3 rounded with low semicircular posterior lobe between setae st. Relative lengths of setae: a 1 = 10, a 2 = 5, a 3 = 15, st = 4. Setae subsimilar, a 2 an st cylindrical blunt, a 1 and a 3 tapering, a 3 pointed, all curved inwards and with short pubescence. Distance a 1 - a 1 0.7 of the length of a 1, distance a 1 -a 2 3.0 times as long as distance a 2 - a 3, distance st-st 2.3 times as long as st and 1.3 times as long as distance a 1 - a 1. Sternum. Posterior margin between insertion areas of setae b 1 indented shallowly. Relative lengths of setae (pygidial a 1 = 10): b 1 = 72, b 2 = 20. These setae tapering pointed, annulated distally, b 1 1.2 times as long as interdistance, b 2 0.9 of distance b 1 - b 2. Anal plate (Figs 28–29) nearly square with a posteromedian V-shaped incision reaching the middle of the plate. Two short appendages protruding upwards from the distal parts of the posterior branches.
