ADULT FEMALE. Diagnosis. Ferrisia uzinuri can be diagnosed by the following combination of features: absence of clusters of small oral-collar tubular ducts on ventral margins of all abdominal segments; ventral oral-collar tubular ducts often with a discoidal pore touching rim, pore sometimes indistinct and usually only slightly smaller than opening of associated duct; dorsal enlarged tubular ducts totalling 63–117 throughout dorsum, rim of each duct usually with 1 or 2 oval discoidal pores typically adjacent to duct opening; auxiliary setae short (12–28, usually ≤20, µm long) and slender; dorsal setae scarce, scattered and very short compared with ventral setae, each 12–38 (mostly 20–30) µm long; multilocular disc-pores on venter of abdominal segments VI (5–9), VII (12–27), and VIII + IX (12–23); anal lobe cerarii each with 2 conical setae; both pairs of ostioles present but anterior pair weakly developed.

Ferrisia uzinuri is similar to F. virgata and F. kondoi but the adult female has a shorter body than adult females of these two species, and slide-mounted specimens of F. uzinuri can be distinguished most readily by lacking clusters of small oral-collar tubular ducts on the ventral margins of the abdominal segments (usually present on segments VI–VIII or VII–VIII for F. kondoi and on VII–VIII for F. virgata ) and generally shorter dorsal setae (up to 38 µm long in F. uzinuri , compared with up to 60 µm long in F. kondoi and up to 65 µm long in F.virgata ). The adult female of F. uzinuri also differs from that of F. virgata in the position of the discoidal pores which, if present near a duct, are always adjacent to the duct opening for both enlarged ducts and ventral oral-collar tubular ducts (discoidal pores never adjacent to duct openings in F. virgata ). This species also shares some morphological similarity with F. malvastra and F. terani , but can be separated from these species by having more (always more than 2) multilocular disc pores ventrally on abdominal segment VI.

Description of slide-mounted specimens (based on holotype and 16 paratypes; Fig. 20). Body 1.88–2.96 mm long (holotype 1.93 mm), 0.96–1.85 mm wide (holotype 0.97 mm). Eye marginal, 45–75 µm wide. Antenna 8 segmented, 420–540 µm long; apical segment 90–110 µm long, 27–32 µm wide. Clypeolabral shield 135–175 µm long, 130–160 µm wide. Labium 137–185 µm long, 87–120 µm wide. Anterior spiracles 55–75 µm long, 30–45 µm wide across atrium; posterior spiracles 62–90 µm long, 42–60 µm wide across atrium. Circulus oval, 102–160 µm wide, divided by intersegmental line. Legs well developed; hind trochanter + femur 310–420 µm long, hind tibia + tarsus 320–400 m long, hind claw 30–35 µm long. Ratio of lengths of hind tibia + tarsus to hind trochanter + femur 0.9–1.1, ratio of lengths of hind tibia to tarsus 2.2–2.8, ratio of length of hind trochanter + femur to greatest width of femur 4.2–4.9. Tarsal digitules subequal, each 47–55 µm long. Claw digitules subequal, each 30–35 µm long. Translucent pores present on hind legs, totalling 15–41 on coxa, femur and tibia combined. Ostioles: both pairs present; each anterior ostiole poorly developed, with 19–24 trilocular pores and 5–6 setae; each posterior ostiole with 21–48 trilocular pores and 5–12 setae. Anal ring 102–160 µm wide, with 6 anal ring setae, each seta 180–238 µm long.

Dorsum. Anal lobe cerarii each with 2 conical setae, 27–35 µm long, with 18–37 trilocular pores and 3–6 auxiliary setae. Dorsal body setae short and slender, each 12–38 µm long. Trilocular pores each 4–5 µm in diameter. Enlarged tubular ducts totalling 63–117 on dorsum, each duct 30–35 µm long, 5–6 µm wide at midlength, duct opening surrounded by a circular sclerotised rim 8–13 µm in diameter and enlarged sclerotised circular area 15–25 µm in diameter, enclosing 1–2 oval discoidal pores (generally adjacent to duct opening) and with 1–5 (generally 2–3) setae, each 12–28 (usually ≤20) µm long, usually either within rim (especially on abdomen) or on edge of rim (especially on head); ducts distributed marginally in clusters of 2–6 on head and thorax, on margins of all abdominal segments in groups of 2–5 (mostly 2–3), but with 6–9 ducts on each side of abdominal segment VII, and also 5–7 medially to submarginally on head and thorax, 3–4 medially on abdominal segments.

Venter. Body setae slender, each 12–175 µm long, longest setae medially on head; apical seta of anal lobe 205–263 µm long. Multilocular disc pores present on posterior abdominal segments only: 5–9 pores on segment VI, 12–27 on segment VII, 12–23 on segments VIII + IX; each pore 7–10 (mostly 7–8) µm in diameter. Trilocular pores each 3–4 µm in diameter. Discodial pores each 1.0–2.5 (generally 2.0) µm in diameter, almost always associated with oral-collar tubular ducts, usually only slightly smaller than opening of associated duct but often indistinct, with 1 pore (rarely 2) touching rim of most oral-collar tubular ducts. Oral-collar tubular ducts each 8.7–10.0 µm long, 2.5 µm wide, totalling 22–37, distributed as follows: 10–24 on head and thorax, and on abdominal segments: 2–4 total on segments I–III; 2–5 on IV; 2–5 on V; 2–5 on VI; 6–11 on VII; 0–2 (generally none) on VIII; no clusters of oral-collar tubular ducts present on body margin.

Etymology. This species is named for the late Dr Uzi Nur, who recognised the cryptic species diversity of Ferrisia mealybugs in the 1970s based on electrophoretic comparison of their enzymes. Nur referred to this species, which we name in his memory, by his code “FK”.

Taxonomic notes. Dr Uzi Nur sent adult male specimens of this and other Ferrisia species to the late Dr John (Jack) W. Beardsley for study. Beardsley found morphological differences among the adult males of the samples that Nur identified as different species based on enzyme electrophoresis. For Nur’s species FK (our F. uzinuri ), Beardsley reported that the adult male was the most distinctive of all of the species, being distinctly smaller, with relatively short antennae, and short setae on the legs and antennae (J.W. Beardsley, in letter to U. Nur, 9 March 1979). In further correspondence Nur noted that his species FK was so far known only from Florida and that live females “look the least virgata -like, since they lack the characteristic dark body color and markings. In other respects such as body shape and glass-like long wax filaments, they are similar to the others. Moreover, in their enzymes they are also not much more dissimilar than most of the other species to one another.” (U. Nur in letter to J.W. Beardsley, 26 March 1979).
