Remarks

• Systematics: The adult female of D. bambusae differs from all other known Discochiton species in having: (i) a much larger body; (ii) a ventral band of sclerotisations in submedial areas of body; (iii) many stigmatic setae in each stigmatic cleft; and (iv) many marginal setae. While the morphology of the new species agrees with most character-states of Discochiton, the adult female displays a greater number of marginal radial lines and more stigmatic spines than are found on other Discochiton species. This may be due to the large body size of D. bambusae, which is the largest species in the genus, reaching approximately 15 mm long. In addition, the legs of D. bambusae are much reduced (similar to those of D. paucipedis (Hodgson)), whereas other species of Discochiton show only fully developed or completely reduced legs. Moreover, the sclerotized plate-like areas on the venter of D. bambusae, which extend in a submedial band from the antennae to the anal cleft, are unique and have not been recorded previously in other species of Discochiton. (Choi & Lee, 2023)
• Structure: Body of adult female flat and broadly oval. Body camouflaged on bamboo, greenish or yellowish. Dorsal surface sclerotized, translucent and reticulated, with many indentations. Ventral surface also slightly sclerotized, almost transparent but with white translucent areas submedially on body; central concave brood space also present. First-instar nymphs reddish, elongated oval. (Choi & Lee, 2023) Slide-mounted adult female. Body circular to oval (broadest across abdomen), 10.1–14.5 mm long and 7.9–11.9 mm wide. (Choi & Lee, 2023)
