Remarks

• Systematics: This species is similar to Cerococcus artemisiae (Kosztarab & Vest, 1966). Like C. deklei and C. kalmiae, C. russellae has the 8-shaped pores on the dorsum arranged in a lattice-like pattern, as also found in species of Cerochiton (described as new above). However, the structure of the apices of the stigmatic pore bands is very different from that on species of Cerochiton as is the distribution of the larger dorsal tubular ducts.
• Structure: Adult female is broadly pyriform, almost circular (Kosztarab & Vest, 1966). The adult female of C. russellae is characterized by the following combination of character-states: (i) 8-shaped pores on dorsum in a lattice-like pattern; (ii) 8-shaped pores on dorsum of two sizes, both quite small; (iii) larger pores restricted to near stigmatic pore bands; smaller pores throughout rest of dorsum; (iv) cribriform plates in two submedial groups of 15–24 on each side of abdominal segment IV; (v) tubular ducts of one size; (vi) multilocular disc-pores absent; (vii) stigmatic pore bands bifurcated; (viii) stigmatic pore bands with abundant spiracular disc-pores, and (ix) leg stubs present. In the the type specimens, many of the leg stubs have distinct digitules and several small pores, here believed to be setal sockets; this has not been noted in other species. The leg stubs on the non-type specimens from Guatamala are different in shape and lack digitules. (Hodgson & Williams, 2016)
