Remarks

• Systematics: In China, the adult female of N. chenopodium is morphologically close to that of N. cucurbitae Tang & Hao (redescribed below) in having the following character states: (i) multilocular disc-pores without a bright central loculus; (ii) posterior multilocular disc-pores each with 1 or 2 rings of loculi, and (iii) abdomen with fold structures. The adult female of N. chenopodium differs by having (contrasting character states in N. cucurbitae are given in parentheses): (i) body relatively small, 5–7 mm long (body large, 14–16 mm long); (ii) claw with an acute prominent basal heel (claw with a rounded prominent basal heel); (iii) multilocular disc-pores forming segmental bands, each 1 or 2 pores wide, across abdominal segments I–IV (bands of multilocular disc-pores across these segments each 3–6 pores wide); (iv) abdominal segments each with long hair-like setae forming interrupted segmental transverse bands, each 1–5 setae wide (bands each 6–12 setae wide) (Zheng & Wu 2024).
• Structure: Unmounted female: Body broadly oval, yellowish white, soft and hairy; foreleg fossorial and well developed, middle and hind legs small (Zheng & Wu 2024). Slide-mounted material: Body ovoid, 5.2–7.0 mm long and 4.5–5.0 mm wide; derm membranous. Antennae 6 segmented, each 273–365 μm long in total, stout; all segments subequal in length, each 45–85 μm long. Scape (segment I) membranous and broadest, 170–210 μm wide, with 6–11 hair-like setae each 38–245 μm long; remaining segments sclerotized, gradually narrowing towards apex; pedicel (segment II) with a group of sensilla; segments II–V each with 0–4 long hair-like setae, 3–8 sensory setae and 0–2 short hair-like setae (each 7–15 μm long); apical segment narrowest, 88–93 μm wide, with 3 or 4 long hair-like setae, 2–5 sensory setae, 1 or 2 short hair-like setae and a group of 4 or 5 sensory organs. Eyespots and mouthparts absent. Thoracic spiracles developed (Zheng & Wu 2024).
• Biology: Adult N. chenopodium appear in Nei Monggol in June. The local people reported having seen adult males of the species, but these have not been collected (Zheng & Wu 2024).
• General Remarks: See Zheng & Wu (2024) for detailed description and illustrations of nymphs and adult.
