description: Neogreenia lonicera Wu & Nan, 2012
Neogreenia lonicera Wu & Nan 2012: 47. Type data: CHINA: Inner Mongolia, Helan Mountain, Bayan Hot, under the bark of Lonicera microphylla. Holotype, female, by monotypy and original designation. Type depository: Beijing Forestry University, Beijing, China.
Host plants: Lonicera microphylla Willd. ex Roem. et Schult. (Caprifoliaceae).
Distribution: China (Inner Mongolia).
Remarks. Wu & Nan (2012) described and illustrated the adult female, first-instar nymph and second-instar nymph. After examining original material of cysts of N. lonicera, we noticed that the cyst stage described by Wu & Nan (2012) was not a “second-instar nymph” but a third-instar female nymph, since their specimens had the anterior 6 abdominal spiracles each with sieve-like disc-pores in the atria (a diagnostic character for third-instar female nymphs). The second-instar nymph of N. lonicera is therefore described below.
Material examined. Paratypes: 2 second-instar nymphs, CHINA: collection data same as for holotype, mounted together with 2 third-instar ♀♀ nymphs.
Second-instar nymph (cyst) (sexes indistinguishable)
Slide-mounted material (n=2) (Fig. 5). Body oval, 1.2–1.6 mm long and about 0.8 mm wide; derm membranous but posterior apex slightly sclerotized. Antennae (Fig. 5A) situated close together medially on head; each reduced, plate-like, 15–18 μm in diameter, with margin sclerotized and protruding anteriorly, and bearing 5–7 setae, each seta 10–20 μm long. Eyes absent. Labium (Fig. 5B) 2 segmented, about 100 μm long and 80–83 μm wide; segment I with a pair of short setae (each about 5 μm long) on each side; segment II with 2 apical hair-like setae (each about 30 μm long) on each side. Clypeolabral shield longer than labium, 230–250 μm long and 125–130 μm wide; stylets present. Legs absent. Thoracic spiracles (Fig. 5C) sclerotized, each with opening 10–13 μm in diameter, a sclerotized bar and a group of 4 or 5 sieve-like disc-pores (Fig. 5D) at inner end of atrium. Abdominal spiracles numbering 8 pairs, with anterior 5 pairs sclerotized; anteriormost pair (Fig. 5E) each with opening about 10 μm in diameter, and 2 sieve-like disc-pores within atrium; spiracles (Fig. 5F) on abdominal segments II– V smaller, each with opening about 7.5 μm in diameter, and 1 sieve-like disc-pore within atrium; posteriormost 3 pairs unsclerotized and tube-like, each with opening about 2.5 μm in diameter and without pores in atrium. Anal opening 12–15 μm wide, with U-shaped sclerotized ring lacking pores or setae, located medially on posteriormost dorsal segment. Cicatrices absent.
Dorsum. With disc-pores of 2 types: (i) large simple pores (Fig. 5G), each about 10 µm in diameter; usually 1 pore present submarginally on each segment, but some segments with 2 pores or none; and (ii) compound multilocular disc-pores (Fig. 5H), each about 7.5 µm in diameter, with 4–7 (mostly 5 or 6) subcentral loculi and distinct peripheral loculi, present on margins from head to abdominal segment II. Setae (Fig. 5I) of only 1 type, spine-like, each 5–10 μm long, present in submarginal and submedial areas.
Venter. With disc-pores of 2 main types: (i) compound multilocular disc-pores (Fig. 5H), same size and structure as on dorsum; forming group around each thoracic spiracle and present on margins except for 2 posteriormost segments; also smaller ones (Fig. 5J), each about 5 µm in diameter, with 3–5 subcentral loculi but without peripheral loculi, numbering 2 or 3 between antennae; and (ii) sieve-like disc-pores (Fig. 5D), each 5–7 µm in diameter, with many irregularly distributed loculi, present within atria of thoracic spiracles and anterior 5 pairs of abdominal spiracles. Setae of 3 types: (i) hair-like setae, each 13–18 μm long, situated on prothorax submedially, below mesothoracic spiracles and submarginally on abdominal segment I; (ii) spine-like setae (Fig. 5I), same size as on dorsum, few on head margin; and (iii) short conical spine-like setae (Fig. 5K) with sclerotized basal sockets, each about 5 μm long; with 1 or 2 near each hair-like seta, 2 or 3 near each thoracic spiracle, and 0 or 1 near each abdominal spiracle except for posteriormost pair.
