Remarks

• Systematics: Si. koebeli Green is not conspecific with C. banksiae, differing as follows (details for C. banksiae, are given in brackets): (i) structure and distribution of tubular ducts on the dorsum are very different; (ii) submarginal tubercles absent (present, each with satellite tubular ducts); (iii) dorsum without small sclerotised areas in submargin, each with a blunt spinose seta (small sclerotised areas present); (iv) anterior and posterior margins of anal plates subequal in length (anterior margin clearly shorter than posterior margin); (v) marginal setae stoutly spinose (finely spinose); (vi) stigmatic clefts shallow (stigmatic clefts deep); (vii) stigmatic spines forming a group, with some displaced some distance onto dorsum (spines forming a group, mainly along cleft margin); (viii) multilocular disc-pores present throughout abdomen and extending onto thorax (restricted to abdominal segment VII); (ix) each band of spiracular disc-pores broad (band only 2 or 3 pores wide); (x) ventral tubular ducts present throughout abdomen and forming a broad marginal band (restricted to a narrow marginal band); (xi) long pregenital setae present on abdominal segments VII and VI (present on segment VII only); (xii) tarsal digitules subequal in length to claw digitules (shorter than claw digitules); and (xiii) antennae 8 segmented (6 segmented). (Hodgson, 2026)
• Structure: "Adult female before gestation of the usual Lecanoid form; oblong oval, convex above, smooth, often with an inconspicuous medial carina, rounded in front, pointed behind. Colour olive brown to reddish brown above, pale olive-green beneath; dorsum sometimes with delicate polygonal plates; eyes and anal operculum black; a crenulate line of white secretion on each side of dorsum – at some little distance from margin – marking the future position of the waxy ridges. After gestation, the body is elevated behind by the accumulation of eggs, which are enclosed in a compact fluted, pale ochreous ovisac, overlapping the margins of the body, but leaving the central dorsal area exposed. This ovisac bears eight more or less prominent ridges on each side, including a pair of prominent earlike processes at the anterior end of the insect (Fig. 1X). The medial dorsal area – in fresh examples – is thinly coated in ochreous mealy powder but becomes denuded in older specimens.” “Ovisac 10 mm long, 8 mm wide and 7 mm high” (Green 1909). Slide-mounted material. Body large and oval, rounded anteriorly, broadest across posterior of thorax, with shallow stigmatic clefts
• Biology: Rutherford (1914) presented observations on copulatory behaviour of the male.
