Remarks

• Systematics: Fragorbis stipites is not likely to be confused with any other species of Fragorbis. The extremely reduced legs and slightly invaginated, U-shaped anal ring are unmistakable. (Hardy & Gullan, 2007)
• Structure: Adult female: Body outline almost circular, length 2.1-3.86 (3.86 for holotype) mm, greatest width 1.7- 3.52 (3.52 for holotype) mm. Eyes ca. 20 µm wide. Antennae 6-segmented; length 75-92 mm; with 2 or 3 hair-like setae on segment I, 1 or 2 hair-like setae on segment II, 0 or 1 setae on segment III, 2 hair-like setae on segment IV, 1 fleshy seta on segment V, and ca. 4 hair-like + 3 fleshy setae on segment VI. Frontal lobes broad and flat, posteromedial of antennae, appearing as 2 areas of convoluted cuticle, ca. 75µm wide. Tentorial box 192-257 µm long, 170-270 µm wide. Labium ca. 175 µm long, 110-159 µm wide. Spiracles 62-95 µm long, 25-40 µm wide across atrium. Holotype with legs reduced to hemispherical lobes, composed of fragmented, ring-like segments; hind legs (118, 105 µm wide, ca. 100 µm long) much larger than fore (50, 46 µm wide*) or mid legs (55, 50 µm wide); paratype with legs not as reduced, segments clearly differentiated; fore legs ca. 40 µm long; mid legs ca. 55 µm long; hind legs ca. 110µm long, hind tibia + tarsus globose, ca. as long as inner margin of hind trochanter; claw 9 mm long; tarsal digitules truncate, 10-14 µm long; claw digitules ca. 5 mm long; translucent pores 1-3 µm in diameter, total of 60-100 on both surfaces of each hind leg. Anal ring 25-30 µm wide, open posteroventrally, slightly invaginated into dorsal surface, bearing 6 setae, ca. 10 µm in length. Caudal setae 17-35 µm long. Dorsum. Derm membranous. Dorsal setae ca. 5 µm long. Macrotubular ducts ca. 10 µm long, orifice with distinct rim 4 µm in diameter; found along margin and in transverse row across each body segment. Quinquelocular disc pores 6 µm in diameter, distributed around posterior margin. Venter. Setae similar to those on dorsum, 10-14 µm long. Macrotubular ducts similar to those on dorsum; in transverse row across each of abdominal segments IV-VIII and throughout margin and submargin. Quinquelocular disc pores dense around vulva, clustered around each spiracle and mouthparts. (Hardy & Gullan, 2007)
