Remarks

• Systematics: According to the keys in Morrison (1928) and Gavrilov-Zimin (2018), this species belongs to either the tribe Monophlebini Signoret sensu Morrison or the tribe Labioproctini sensu Gavrilov-Zimin. (Li, Xu & Wu, 2023)
• Structure: Body of adult female oblong oval, convex dorsally, orange yellow to red; naked just after the final moult, mature adult female covered dorsally by a solid waxy test.Test also oblong oval, about 7.5–8.5 mm long, 6.0–7.0 mm wide and 5.5–6.5 mm high, strongly convex above, sides compressed and slightly concave, bearing marginal and dorsal tufts of wax processes, but with little secretion between the tufts. (Li, Xu & Wu, 2023) Slide mounted adult female oval, 5.1–7.8 mm long, 2.6–4.0 mm wide. Derm lightly sclerotized except ventromedial abdomen embranous and with corrugated folds. Antennae (Fig. 2A) each 10-segmented with basal segment broadest, tapering distinctly to apex. Eyes sclerotized, each hemispherical, situated laterad of scape. (Li, Xu & Wu, 2023) Adult male body 4–6 mm long, cylindrical with abdomen slightly depressed. Wingspan about 9.5 mm. Membranous parts of body yellow, sclerotized parts brown. Antennae each long and filiform, 10-segmented; basal 2 segments short and stout. Compound eyes large and dark. Fore wings each large and broad with membrane smoky in color and costal complex brown. Legs slender. Abdomen 8 segmented, segment VIII with a pair of long caudal extensions. (Li, Xu & Wu, 2023)

  First-instar nymph elliptical, with many long marginal wax filaments, each about 5 times as long as body; antennae and legs well developed; body yellow, legs and antennae orange. According to the keys in Morrison (1928), the first-instar nymph of C. castanopsis is closest to that of Walkeriana, sharing the following characters: (i) a line of large bilocular tubular pores along the margin; (ii) marginal setae relatively long, each approaching the length of an apical seta; (iii) venter with a single medial cicatrix; (iv) each dorsal spine group outlined by a row of quadrilocular disk pores; and (v) anal opening surrounded by a circle of short fimbriately tipped setae and a ring of multilocular pores. However, C. castanopsis differs from Walkeriana in having (contrasting characteristics of Walkeriana given in parentheses): (i) anal tube with a single row of multilocular pores on wall about at mid-length (with a double row of multilocular pores); and (ii) ventral hair-like setae densely clustered on medial area of mesothorax (hairs on ventral medial area of mesothorax inconspicuous and not clustered).
