Remarks

• Systematics: This species is near Cerococcus corokiae according to Maskell (Cockerell, 1898j) and to C. tuberculus (Hamon & Kosztarab, 1979).
• Structure: Old females are rounded and dull black. Adult female lies loose within a mass of empty yellowish white empty egg pellicles. Dried female is dark purple. Male scales are small and elongate, dark in color with a red or yellowish tint (Cockerell, 1898j). Female test is extremely convex, elliptical with anterior and posterior ends pointed (Lambdin & Kosztarab, 1977a). The adult female of C. koebelei is characterized by the following combination of character-states: (i) 8-shaped pores on dorsum randomly distributed, not in a lattice-like pattern; (ii) 8-shaped pores on dorsum of three sizes, all quite small; (iii) larger 8-shaped pores restricted to near stigmatic pore bands; smallest pores restricted to within stigmatic pore bands; (iv) cribriform plates elliptical, present in submedial groups of two on each side of abdominal segment IV, anterior plate larger and more elliptical than posterior plate; (v) dorsal tubular ducts of two sizes present, broader ducts restricted to posterior abdominal segments; narrower ducts frequent elsewhere; (vi) multilocular disc-pores present in broad bands across all abdominal segments and also metathorax; (vii) stigmatic pore bands bifurcated; (viii) stigmatic pore bands with fairly abundant spiracular disc-pores, and (ix) leg stubs present. (Hodgson & Williams, 2016)
• General Remarks: Lambdin & Kosztarab (1977a) give detailed description and illustration of adult female. Hamon & Kosztarab (1979) provide a detailed description and illustration of the first instar.
