Remarks

• Systematics: C. toddaliae is close to both C. eucleae and C. eugeniae. The main difference between C. toddaliae and these 2 species is the greater number of marginal stigmatic setae in each cleft, stretching outwards so that they generally clearly meet between clefts. C. toddaliae is similar to C. eucleae in having the stigmatic setae in each cleft 3 deep (usually 4 deep on C. eugeniae), and it resembles C. eugeniae in having more non-marginal stigmatic setae than on C. eucleae (2-13 on C. eucleae, 13-23 on C. eugeniae and 12-21 on C. toddaliae); however, the stigmatic setae never meet between clefts on C. eucleae and, when they do meet on C. eugeniae, they are clearly denser within each cleft than between the clefts (as dense on C. toddaliae). Hodgson & Peronti, 2012
• Structure: Unmounted material. "Test of the adult female highly convex; the dome with a shallow median depression carrying a very small elongate boss, longitudinally orientated, rising from its base. Submarginal depression confined to a lateral indentation on either side above the stigmatic areas. The test is waxy white, often somewhat semi-transparent, and is characterised by thin radiating lines of dark colour of indeterminate hue. These lines resemble a shaded pencil effect; they are fine, straight, close together as they leave the boss but gradually diverge and become fainter. Diameter of test of adult female 5-6.5 mm." "Denuded of wax, the female is not very convex, but the central portion of the dermis, or dome, assumes the form of a laterally compressed cone. Sub-marginal area flattened with what appears to be numerous irregularly shaped and distributed depressions of a darker colour. The marginal area is flattened, with 3 rounded bi-lateral tubercles and a cephalic tubercle. These tubercles have a few faint dark marks simulating those of the submarginal region, but less conspicuous. Beneath the extension of the integument carrying the tubercles there is a marked narrow but deep indentation separating it from the true margin which is correspondingly flattened. Caudal process very short, triangular, directed upwards at an angle of 30-45 degrees. The caudal process is dark brown with a clearly defined circular circumscribed chitinous area in the younger examples. Stigmatic clefts shallow but well marked." (Hall, 1931). Mounted material. Body oval, probably rather convex, with shallow, stigmatic clefts; dorsum probably with distinct tubercles. Caudal process short and stout. Length 1.5-3.0 mm, total width of mounted specimen 1.57-2.2 mm; width of venter 1.8 mm. (Hodgson & Peronti, 2012)
