• HardyGu2007: pp.109-116 ( Adult (F) ) [Key to the adult females of species of Fragorbis]

Remarks

• Systematics: Fragorbis fructus is most similar to F. superfacies. The adult female can be distinguished from that of F. superfacies by its (1) numberous large translucent pores on all segments of the hind legs; (2) hind legs with no more setae than fore or mid legs; (3) absence of Quinuelocular pores from dorsum, and scarcity of these pores on venter; (4) single size class of macrotubular duct; (5) setae up to 45 µm long along posterior body margin; and (6) absence of conspicuous anterior extensions of the tentorial box. (Hardy & Gullan, 2007)
• Structure: Adult female: Body outline ovate; length 0.92- 1.68 (1.68 for holotype) mm, greatest width 0.70-1.30 (1.30 for holotype) µm. Eyes 18-23 µm wide. Antennae 5-segmented, apex composed of 2 incompletely fused segments; length 58-75 µm; with 3 hair-like setae on segment I, 1 or 2 hair-like setae on segment II, 2 hair-like setae on segment III, 1 fleshy seta on segment IV, 6 or 7 hair-like setae + 4 fleshy setae on segment V. Frontal lobes absent. Tentorial box 168- 200 µm long, 130-180 µm wide. Labium 75-112 µm long, 87-112 µm wide. Spiracles 50-62 µm long, 20-25 µm wide across atrium. Legs moderately reduced, tibia and tarsus partly fused; fore and mid legs: trochanter + femur 68-100 µm, tibia + tarsus 43-57 µm; trochanter + femur 125-153 µm, tibia + tarsus 75-95 µm; claw 15-22 µm; coxa with 6 setae, trochanter with 4 setae, femur with 5 setae, tibia with 4 setae, tarsus with 5 setae; tarsal digitules 20-28 µm long, claw digitules 12-18 mm long; translucent pores ca. 2 µm in diameter, on every segment of hind leg, ca. 125 pores on dorsal surface and ca. 35 pores on ventral surface. Anal ring 38-57 µm wide, composed of 4 isolated fragments, surrounding anal opening, each anterodorsal ring fragment bearing a pair of setae, each posteroventral fragment bearing a tight cluster of 1-3 setae; ring setae 15-22 µm long. Pair of elongate caudal setae 50-67 µm long. Dorsum. Derm membranous. Dorsal setae 12-20 µm long, in a transverse band or row across each body segment. Macrotubular ducts ca. 13 µm long, each with distinct oral rim ca. 4 µm in diameter; distribution similar to dorsal setae. Quinquelocular disc pores absent. Venter. Ventral setae 10-15 µm long. Macrotubular ducts same as those on dorsum, dense near margin, sparsely scattered bands across each body segment. Quinquelocular disc pores 5 µm in diameter; a few associated with each spiracle and scattered on posterior abdominal segments with modest concentration near vulva. (Hardy & Gullan, 2007)
