Remarks

• Systematics: Adult females of A. roseus (Green) are morphologically extremely similar to those of A. indicus.Based on the type series of A. roseus, these two species can be separated by the shape of the intermediate-sized pores, which are much rounder on A. roseus. Hodgson & Williams stated that t 6+ loculate pores were occasionally present in the stigmatic pore bands of both A. indicus and A. roseus (although they tended to be more frequent in the latter species), and all of the specimens of A. roseus had exactly the same layout of the cribriform plates as in A. indicus. Lambdin and Kosztarab were unable to borrow material of Phenacobryum indigoferae but here they consider that the name P. indigoferae to be a junior synonym of C. roseus. The differences between the distribution of the 8-shaped pores on the dorsum were considered to be due to age and environmental factors. (Hodgson & Williams, 2016)
• Structure: Test of adult female with dorsum completely concealed beneath dense conical or rounded tufts of rosy pink. Adult female broadly oval (Green, 1909a). Female test is brownish with white waxy projections, 3.0 mm long and 2.8 mm wide. The dorsum possesses 2 sizes of 8-shaped pores arranged in a swirl pattern, an anal ring with 8 setae, and cribriform plates in 2 submedial groups (each group subdivided into 2 clusters) on one posterior abdominal segment with 2-8 plates per cluster (Lambdin & Kosztarab, 1977a). The adult female of A. roseus is characterised by the following combination of character-states: (i) dorsum with three sizes of 8-shaped pores; (ii) large and intermediate-sized 8-shaped pores in fairly dense swirls throughout most of dorsum; (iii) intermediate-sized pores with very rounded closed pores on each side; (iv) smallest 8-shaped pores sparse in apices of each stigmatic pore band; (v) cribriform plates in submedial groups on both abdominal segments IV and III, with three or four plates on each side of IV and one or two on each side of III; (vi) leg stubs large; (vii) posterior stigmatic pore band bifurcated; (viii) multilocular disc-pores very few, restricted to submargins of most abdominal segment and also sometimes metathorax; (ix) a few ventral 8-shaped pores present near clypeolabral shield, and (x) antenna without either a cone-like apex or a shallow setal cavity.
