Remarks

• Systematics: This species is close to C. kalmiae and is the only species with acorn shaped spiracular setae that does not occur in North or South America (Hamon & Kosztarab, 1979). The adult female of C. ficoides is similar to those of C. bernardi and C. javanensis, sharing with them: (i) stigmatic pore bands with the same structured apex; (ii) fleshy setae associated with each stigmatic pore apex, and (iii) at least two sizes of tubular ducts on the dorsum, the larger present on each side of the lattice-like lines of 8-shaped pores. (Hodgson & Williams, 2016)
• Structure: Female test is subcircular, presenting a budlike appearance on twigs, concave dorsally and brown in color. Adult female is pear shaped (Lambdin & Kosztarab, 1977a). The adult female of C. ficoides is characterised by the following combination of character-states: (i) anteroventral sclerotizations absent; (ii) three finely spinose setae present along inner margin of each anal lobe; (iii) dorsal fleshy setae on anal lobes rather spinose and bullet-shaped; (iv) posteroventral seta on each anal lobe absent; (v) dorsum with three sizes of 8-shaped pore; (vi) smallest 8-shaped pores forming a lace-like pattern throughout dorsum and margins of venter; (vii) largest 8-shaped pores restricted to within and around apices of each stigmatic band; (viii) apex of each stigmatic pore band with round groups of 4–10 sunken 8-shaped pores in centre; (ix) lateral margins of posterior abdominal segments without large 8-shaped pores; (x) cribriform plates represented by a single plate medially on abdominal segment IV (Taiwanese material with a submedial group of 3–7 plates on each side); (xi) stigmatic bands quite long and extending onto dorsum; (xii) tubular ducts of two sizes on dorsum, broadest in a line on either side of each lace-like pattern and medially on posterior abdominal segments; (xiii) leg stubs absent; (xiv) stigmatic pore bands bifurcated; (xv) multilocular disc-pores present on posterior abdominal segments; (xvi) spiracular disc-pores extremely few near spiracles but quite abundant in each stigmatic pore band apex, and (xvii) antennae without either a cone-like apex or setal cavity. (Hodgson & Williams, 2016)
• General Remarks: Detailed description and illustration by Lambdin & Kosztarab (1977a). Hamon & Kosztarab (1979) provide a detailed description and illustration of the first instar. Detailed redescription and illustration in Hodgson & Williams, 2016.
