28 (27) Marginal setae and setae of the middle region of the dorsum nearly equal in length, 1/16 to 1/10 as long as the idiosoma, 25 to 70 µm long, however caudal setae Z 5 in some species longer.

29 (32) Sternal setae-pair st1–st1 localized together just as narrow as setae-pair st3–st3.

30 (31) Posterior part of the peritrematal shields very slender, 1/2 the width of coxae IV, dorsal setae remarkably short, 25 to 30 µm long, lateral branches of the tectum reduced to two pairs of tiny points, 1/20 the length of the middle branch, idiosoma 550 µm long
