Nakahara( USNM).   Paratypes: PUERTO RICO: 2 adult ♀(1 slide) ex  Inga inga, 14 kmE of Mayaguez,  6.ii.1936, M.R. Smith, P.R. No: 1354 ( USNM);  2 adult ♀(1 slide) ex guaba [  Ingasp.] leaves, Mayaguez,  20.xii.1935, M.R. Smith, P.R. # 876 ( USNM);  1 adult ♀(on slide with an adult ♀of an unidentifiable  Ferrisiasp.), ex  Inga inga, San Sebastian,  5.xi.1935, M.R. Smith, Acc# P.R. 848 ( USNM).  ADULT FEMALE. Diagnosis.  Ferrisia millerican be diagnosed by having the following combination of features: clusters of small oral-collar tubular ducts on ventral margins of all body segments, but ducts usually in loose clusters; ventral oral-collar tubular ducts generally associated with 1 or 2 discoidal pores around duct rim, pores nearly as large as duct opening and very close to duct opening, each 2.5–3.5 µm in diameter; dorsal enlarged tubular ducts totalling 51–68 throughout dorsum, rim of each duct mostly with 1 or 2 oval discoidal pores usually associated with rim of duct opening; number of multilocular disc pores on venter of abdominal segments as follows: 1–3 on VI, 12–20 on VII, and 10–23 on VIII + IX; both pairs of ostioles present and well developed; antennae 7 or 8 segmented.   Ferrisia milleriis most similar to  F. cristinae,  F. ecuadorensis,  F. kondoiand  F. williamsi, but can be distinguished readily by having clusters of small oral-collar tubular ducts on the ventral margins of all body segments (present on segments II–VIII in  F. ecuadorensis, usually confined to VI–VII in  F. cristinaeand  F. williamsi, and VI–VII or VII–VIII in  F. kondoi). The adult female of  F.millerialso differs from that of  F. virgatain the position of the discoidal pores, which is adjacent to the rim of each duct opening of both dorsal enlarged tubular ducts and ventral oral-collar tubular ducts (discoidal pores rarely adjacent to rim of duct openings in  F. virgata). This species is also similar to some specimens of  F. gilliby having small oral-collar tubular duct clusters on all body segments, but can be separated from the latter by the presence of anterior ostioles and presence multilocular pores on abdominal segment VI (both features absent in  F. gilli).   Description of slide-mounted specimens(based on all 6 typespecimens; Fig. 14). Body elongate oval, 2.98–3.52 mmlong ( holotype 2.57 mm), 1.68–1.92 mmwide ( holotype 1.37 mm). Eye marginal, 68–90 µm wide. Antenna 7 or 8 segmented, 600–650 µm long; apical segment 120–130 µm long, 35–37 µm wide. Clypeolabral shield 170–195 µm long, 110–145 µm wide. Labium 210–235 µm long, 125–145 µm wide. Anterior spiracles 65–75 µm long, 45–50 µm wide across atrium; posterior spiracles 82–88 µm long, 52–68 µm wide across atrium.   FIGURE 14.Adult female of  Ferrisia milleriKaydan & Gullan sp. n. Circulus quadrate, 117–160 µm wide, divided by an intersegmental line. Legs well developed; hind trochanter + femur 470–500 µm long, hind tibia + tarsus 530–560 mlong, hind claw 40–45 µm long. Ratio of lengths of hind tibia + tarsus to hind trochanter + femur 1.08–1.25, ratio of lengths of hind tibia to tarsus 3.00–3.07, ratio of length of hind trochanter + femur to greatest width of femur 3.91–4.27. Tarsal digitules subequal, each 60–63 µm long. Claw digitules subequal, each 35 µm long. Translucent pores present on hind legs, totalling 12–22 on coxa, femur and tibia combined. Ostioles: both pairs present; anterior ostioles poorly developed, each with 25–29 trilocular pores and 8 setae; each posterior ostiole with 33–46 trilocular pores and 7–11 setae. Anal ring 100–120 µm wide, with 6 anal ring setae, each seta 185–225 µm long.  Dorsum.Anal lobe cerarii each with 2 conical setae, each seta 35 µm long, with 27–47 trilocular pores and 3–5 auxiliary setae. Dorsal body setae slender, each 15–88 µm long. Trilocular pores each 4–5 µm in diameter. Enlarged tubular ducts totalling 51–68 on dorsum, each duct 25–33 µm long, 6–8 µm wide at mid-length, rim of duct opening 10–13 µm in diameter, surrounded by a sclerotised circular area 15–25 µm in diameter, enclosing 1 or 2 oval discoidal pores (each pore usually adjacent to rim of duct opening) and with 2–5 (generally 2 or 3) setae, each 25–38 µm long, usually either within rim of duct opening (especially on abdomen) or on edge of rim (especially on head); ducts distributed marginally in clusters of 1–4 on head and thorax, on margins of all abdominal segments in groups of 2–3, but with 4–6 ducts on each side of abdominal segment VII, and also 3–5 submedially on dorsum.  Venter.Body setae slender, each 15–240 µm long, longest setae medially on head; apical seta of anal lobe 300–305 µm long. Multilocular disc pores present on posterior abdominal segments only: 1–3 pores on segment VI, 12–20 on segment VII, 10–23 on segments VIII + IX; each pore 7.5–8.0 µm in diameter. Trilocular pores each 3–4 µm in diameter. Minute discodial pores each 2.5–3.5 µm in diameter, almost always associated with oral-collar tubular ducts, with 1 or 2 pores very close to (almost touching) rim of most oral-collar tubular ducts and 1 or 2 pores among many clusters of small oral-collar tubular ducts. Oral-collar tubular ducts on most of venter (excluding margins of posterior abdomen) each 9–10 µm long, 2.5–3.8 µm wide, totalling 67–74, distributed as follows: 17–22 on head and thorax, and on each abdominal segment: 10–12 total on segments I–III, 4–6, on IV; 4–10, on V; 4–12, on VI; 8–14, on VII, and 2–4 on VIII. Small oral-collar tubular ducts each 7.5–9.0 µm long, 3–4 µm wide, distributed on each side of body as follows: 13–19 on head at base of antennae, in loose segmental clusters of 2–11 ducts along margin of thorax; on each side of each abdominal segment: 3–10 on I; 3–10 on II; 9–15 on III; 7–15 on IV; 8–18 on V; 8–18 on VI; 10–17 on VII; 0–6 on VIII; ducts in each group not tightly clustered.   Etymology.This species is named in honour of Dr Douglass R. Miller, who assisted with this study in many ways, including hosting the authors’ visits to Beltsville to examine  Ferrisiaspecimens in the USNM, collecting  Ferrisiasamples for DNA work, and providing much useful advice. 1977-07-16 USNM S.
