- Systematics: Pragorbis superfacies most resembles F. fructus. In the slide mounted material several elongate glasssy filaments, each arising from one of the larger macrotubular ducts, have been preserved. These filaments were not detected in slide-mounted material of the other species of Fragorbis.
- Structure: Adult female: Body outline ovate; length 1.12-1.92 (1.90 for holotype) mm, greatest width 0.82-1.50 (1.45 for holotype) mm. Eyes ca. 15 µm wide. Antennae 6-segmented, 60-67 µm long; 3 hair-like setae on segment I, 2 hair-like setae on segment II, 2 hair-like setae on segment III, 1 fleshy seta on segment IV, 1 hair-like seta + 1 fleshy seta on segment V, and ca. 6 hair-like setae + 3 fleshy setae on segment VI. Frontal lobes absent. Tentorial box 142-175 µm long, 125-142 µm wide, with anterior extensions ca. 70 µm long. Labium 62-75 µm long, 88-105 µm wide. Spiracles 42-60 µm long, 18-25 µm wide across atrium. Legs moderately reduced, tibia and tarsus partly fused; fore and mid legs: trochanter + femur 47-75 µm, tibia + tarsus 37-57 µm, claw 12-17 µm; hind legs: trochanter + femur 135-167 µm, tibia + tarsus 105-130 µm, claw 20-27 µm; fore coxa with 5 setae, mid coxa with 6 setae, hind coxa with 7 setae, trochanter with 4 setae, fore and mid femur each with 4 setae, hind femur with ca. 10 setae, fore and mid tibia each with 4 or 5 setae, hind tibia with 8 setae, tarsus with 3 or 4 setae; tarsaldigitules on fore and mid legs each 20-30 µm long, those on hind legs 30-40 µm long; claw digitules on fore and mid legs each 12-17 µm long, those on hind legs 13-25 µm long; translucent pores minute or indiscernible, less than 1 µm in diameter, confined to dorsodistal portion of hind femora. Anal ring composed of 2 conspicuous anterodorsal fragments, each with a pair of setae, and 2 smaller posteroventral fragments each with a single seta; ring setae 11-25 µm long, anal opening 37-48 µm wide. Pair of elongate caudal setae 27-33 µm long. Dorsum. Derm membranous. Dorsal setae ca. 10 µm long. Macrotubular ducts of 2 size classes: larger ducts 15-17 mm long, oral rim ca. 10 µm in diameter; smaller ducts 8-10 µm long, oral rim ca. 2.5 µm in diameter; both duct types evenly distributed over dorsum. Quinquelocular disc pores 5 µm in diameter. Venter. Ventral setae 10-15 µm long. Macrotubular ducts same as smaller ducts on dorsum; in a transverse row across each abdominal segment and scattered around margin. Quinquelocular disc pores distributed across each body segment.
- Biology: In Beardsley's field notes, he remarks that the adult females were found in bark crevices, producing cottony ovisacs, and that they were tended by ants.
