Remarks

• Systematics: F. pseudopustulans is very similar to F. pustulans. The folloing features can be used to distinguish beteen these 2 species: F. pseudopustulans has many dorsal macrotubular ducts and relatively few quinquelocular disc pores, and F. pseudopustulans has the dorsal disc more heavily sclerotised. (Hardy & Gullan, 2007)
• Structure: Adult female: Body outline ovate to oval; length 0.76-1.51 (1.51 for holotype) mm, greatest width 0.58-1.11 (1.11 for holotype) mm. Eyes 14-17 µm wide. Antennae (Fig. 14a) 3- to 4-segmented, 30-43 µm long; 2 or 3 hair-like setae on segment I, 2 or 3 hair-like seta on segment II, 2 hair-like setae on segment III, and ca. 6 hair-like setae + 4 fleshy setae on segment IV. Frontal lobes absent. Tentorial box 140-150 µm long, 115-145 µm wide, with anterior extensions each ca. 50 µm long. Labium 55-80 µm long, 63-90 µm wide. Spiracles 50-65 µm long, 25-30 µm wide across atrium. Legs moderately reduced, tibia and tarsus partly fused; fore and mid legs: trochanter + femur 35-65 mm, tibia + tarsus 25-45 µm; hind legs: trochanter + femur 80-112 µm, tibia + tarsus 42-71 µm; claw 11-20 µm; tarsal digitules increasing in size caudad, 12-31 µm long; claw digitules ca. 12. µm long; translucent pores 1-3 µm in diameter: 30-50 pores on dorsal surface of hind coxa, 20-50 pores on ventralsurface of hind coxa, 10-35 pores on dorsal surface of hind femur, 5-15 pores on ventral surface of hind femur, ca. 15 on dorsal surface of tibia + tarsus. Anal ring composed of 4-6 fragments, with 6 ring setae, 10-25 µm long, position of the setae on ring fragments variable; anal opening 43-58 µm wide. Elongate caudal setae 30-45 µm long. Dorsum. Derm of dorsal disc rugose and sclerotic. Dorsal setae 5-20 µm long. Macrotubular ducts 13-16 µm long, oral rim ca. 4 µm in diameter. Quinquelocular disc pores ca. 5 µm in diameter, very few, on margins only. Venter. Ventral setae ca. 10 µm long. Macrotubular ducts same as those on dorsum, found along margin. Quinqeulocular disc pores 5 µm in diameter; sparsely scattered on abdominal segments, in small clusters around each spiracle. First-instar nymph: Body length 235-290 µm, greatest width 140-180 µm. Antennae 5-segmented, 55-60 µm long; 3 hair-like setae on segment I, 2 hair-like setae on segment II, 1 hair-like seta on segment III, 1 hair-like seta + 1 fleshy seta on segment IV, and ca. 4 hair-like setae + 3 fleshy setae on segment V. Tentorial box 55-62 µm long, 45-57 µm wide. Labium 32-34 µm long, 25-33 µm wide. Legs well developed: trochanter + femur ca. 50µm, tibia + tarsus ca. 45µm, claw ca. 11µm, tarsal digitules 18-22 µm long, claw digitules 11-14 µm long. Anal ring 11-13 µm wide, simple, without setae or pores. Anal lobes membranous, anal lobe setae as follows: 1 lateral lobe seta similar to those on margin, 2 medial lobe setae more slender than those on margin, close-set, bases contiguous, 1 caudal setae 73-90 µm long, 1 ventral lobe seta ca. 10 µm long. Dorsum. Derm membranous. Dorsal setae ca. 10 µm long, digitate; 2 longitudinal rows on each side of body, with 1 seta per row on each body segment, abdominal segment I and metathorax each with an additional seta laterad of longitudinal rows; marginal setae similar to those on dorsum, with ca. 10 setae between eyes, ca. 10 setae on each side of thorax, 2 setae on each side of abdominal segment I, and 1 seta on each side of abdominal segments II-VIII. Microtubular ducts ca. 5 µm long; 1 microtubular duct anterior to closeset setae on each side of abdominal segment VIII, 1 microtubular duct between median and submedian rows of setae on each side of abdominal segment I, metathorax, mesothorax and head. Venter. Ventral setae 5-12 µm long, in 3 longitudinal rows on each side of abdomen, 1 seta mesad of each coxa. Head with 3 pairs of elongate (15-20 µm) setae posteromedial of antennae. One trilocular disc pore near each spiracle. (Hardy & Gullan, 2007)
• Biology: Females of F. pseudopustulans live in blister like galls; each 3-5 mm in diameter, on the trunks, stems, branches of tigs of eucalypt trees and saplings. (Hardy & Gullan, 2007)
