Remarks

• Systematics: Prof. Tang Fang-teh (personal communication to Yair Ben-Dov, 7 May 2002) confirmed that Kuwaniella zizyphi Tang, 1984 nomen nudum is identical with Neogreenia zizyphi Tang, 1995. The adult females of N. zizyphi in Zheng, et al., 2024 differ from the original description by Tang & Hao (1995) in having: (i) thoracic spiracles each with a group of 20–27 sieve-like disc-pores at inner end of atrium (Tang & Hao mention 15–16 pores at inner end of atrium); (ii) thick-rimmed simple pores present on abdominal segment VIII (Tang & Hao did not mention these, but it is possible that they might have mistaken these pores for setal sockets whose setae have been lost); (iii) compound multilocular disc-pores each with an outer ring of peripheral loculi (Tang & Hao describe multilocular disc-pores without peripheral loculi, but the structure of peripheral loculi is sometimes difficult to observe); and (iv) vulva situated on venter of abdominal segment VIII (Tang & Hao describe the vulva as being situated between abdominal segments VII and VIII). The adult males of only 2 species of Neogreenia, N. zizyphi and N. osmanthus, have been described in detail. The differences between them are (character states for N. osmanthus in parentheses): (i) prescutum with 18–20 scutal setae on each side (with 9–13 scutal setae on each side); (ii) ventral part of epicranium with subpentagonal sclerotization complete (subpentagonal sclerotization with small circular membranous part anteriorly); and (iii) claw with a pair of pointed digitules, shorter than claw (with a pair of capitate digitules, longer than claw). (Zheng, et al., 2024)
• Structure: Adult female body elongate, with dorsum convex and venter flat; antennae situated on apex of head; legs present; body orange, eyes black. Slide-mounted adult female 4.1–6.3 mm long and 1.8–2.4 mm wide; derm membranous. Antennae10 segmented, situated close to each other, total length of each 1,100–1,125 μm long. Adult male elongate, wing-span 4.1–4.2 mm; with head broad, antennae slender and filiform, neck distinct, fore wings broad, and legs slender. Membranous parts of body red brown, sclerotized parts black brown, eyes black, fore wings clear with anterior margin grey to red brown and pterostigma yellow brown; posterior end of abdomen with a dorsal tuft of long waxy filaments. Second-instar nymph (cyst) (sexes indistinguishable) body oval, yellowish, some specimen with posterior part orange; antennae and legs lacking; living under bark, surrounded by flocculent wax. Slide-mounted body 1.1–1.7 mm long and 0.7–1.0 mm wide; derm membranous, but posterior part or body margin becoming sclerotized at late stage of development. Antennae reduced to small oval plates, each 15–18 μm in diameter, with margin sclerotized and protruding anteriorly; situated close together medially on head, each bearing 4 or 5 setae, each 20–35 μm long. Eyes absent. Third-instar female nymph oval, yellowish, with margin orange; antennae and legs lacking. Slide-mounted body 2.2–3.0 mm long and 1.3–1.7 mm wide; derm membranous medially, sclerotized marginally, with posterior end strongly sclerotized. Antennae reduced to small oval plates, each 24–29 μm in diameter, with margin sclerotized and protruding anteriorly, and bearing 5–7 setae, each 15–58 μm long; situated close together medially on head. Eyes absent. Third-instar male nymph elongate, legs and antennae present, wing buds absent; body orange; medial venter of abdomen, legs and antennae yellowish, eyes black. Slide-mounted body 2.3–4.0 mm long and 0.8–1.1 mm wide; derm membranous. Antennae (Fig. 18A) 9 segmented, each 700–870 μm long. Pupa elongate, antennae and legs present but not capable of movement; body orage, eyes red-brown, antennae, legs and wing buds yellow and almost transparent. (Zheng, et al., 2024)
