Remarks

• Systematics: C. royenae shows some similarity to C. uvariae in having each group of stigmatic setae narrower along the margin than the length of each group but differs in having: (i) only 3 large dorsal setae on each anal plate (thought to be 4 or 5 on C. uvariae); (ii) dorsal setae clearly longer than the width of the basal socket and quite sharply pointed (shorter and blunter on C. uvariae), and (iii) many fewer stigmatic setae in each group (less than 75 rather than well over 100). (Hodgson & Peronti, 2012)
• Structure: Unmounted material. "In general appearance, the tests of the adult female are identical with those of [C.] quadrilineatus as shown in the photograph accompanying Newstead's original description. Closer examination of Rhodesian material, however, shows that the large pyriform bodies described by Newstead are wanting." (Hall, 1931). The test also differs in that "the colour is very dark grey to dull black relieved only by the conspicuous white stigmatic bands; the wax beneath the surface is very little paler but more transparent -- certainly not white; the test is extremely hard, and the adult female as seen from the ventral aspect is brick red." (Hall, 1931). Mounted material. Body probably rather roundly oval and convex, with distinct, quite deep, stigmatic clefts; dorsum with distinct but fairly small, lateral tubercles. Caudal process shallowly conical, set on posterior end of dorsum. Length 2-4 (3.3-4.0) mm, total width 1.7-3.0 (2.5-4.0) mm. (Hodgson & Peronti, 2012)
