Remarks

• Structure: Live adult female ovoid, exposed on the host-plant during the growing period; body with dorsum strongly convex, flattened ventrally, with some powdery secretion; eggs deposited within an internal marsupium having a U-shaped or V-shaped opening (Morrison 1928). Slide-mounted adult female broadly oval, derm not definitely chitinised. Median part of thoracic dorsum dominated by short and long setae. Antennae each with 8‒10 segments. Thoracic spiracles each large but not conspicuous, with bar but without a group of pores at opening. Abdominal spiracles numbering 7 pairs, each much smaller than a thoracic spiracle, inconspicuous, with a thickened rim. Cicatrices numbering 3 set close together, each usually more-or-less irregular in shape. Anal tube short, with a row of wax pores at inner end, somewhat sclerotized. Multilocular disc-pores each with 1, or 3 or 4, circular central loculi and with 5‒8 outer loculi. (Moghaddam & Watson, 2024)
• Biology: Gavrilov-Zimin (2018) reported that the females of Pseudaspidoproctus have an internal marsupium where the eggs are deposited until hatching. The marsupium is formed inside of the abdomen of an adult female as a deep invagination of the ventral surface of the abdominal segments. Found on fronds of the host plant (Hall, 1925).
• General Remarks: Description and illustration of nymph and adult female by Hall (1925), Morrison (1928) and by Borchsenius (1949b, 1950b).
