Remarks

• Systematics: Green (1922) described and illustrated the adult female and male, young larva and nymph, and provided brief descriptions of a later larva (probably a male) and male nymph. According to these descriptions and the syntype material examined by Zheng, et al., it can be inferred that the “young larva” is a first-instar nymph, the “nymph” is a third-instar female nymph, the “later larva” is a third-instar male nymph, and the “male nymph” is a male pupa. Foldi (2001a) listed this species both in Kuwania and in Neogreenia.
• Structure: The general appearance (in color illustration) of the adult female and adult male by Green (1922). Slide-mounted adult female body elongate, about 7.7 mm long and 2.5 mm wide, head narrow and abdominal apex rounded. Derm membranous but margins of posterior abdomen slightly sclerotized. Antennae each 10 segmented, situated close to each other; total length of each about 1,000 μm; each segment with apex membranous, basally and subdistally sclerotized, also with a sclerotized bar on most segments. (Zheng, et al., 2024) Adult male body about 2.2 mm long and 0.6 mm wide across prealare. Setae spine-like, each 5–10 μm long, with a large convex socket (5–9 μm wide), numerous on posterior part of abdomen. Third-instar female nymph body oval, about 2.8 mm long and 1.9 mm wide; head broad and abdomen slightly narrower; derm membranous medially, but posterior abdomen sclerotized marginally. Antennae reduced Eyes absent. Male pupa elongate, about 2.1 mm long and 0.58 mm wide. Antennae each 10 segmented, total length about 1,120 μm; segments almost cylindrical, with similar widths, becoming slightly narrower towards apical segment. Mouthparts absent. (Zheng, et al., 2024)
