Solenococcus tuberculus Hempel 1900: 390 –392.

Cerococcus tuberculus ; Green 1917: 81. Change of combination.

Type details. BRAZIL, São Paulo, on Baccharis sp., 1900, A. Hempel. Depository: USNM: lectotype adf (designated by Lambdin & Kosztarab 1977: 223) and 1/1 paralectotype adf; also 10/61 first-instar nymphs. There is almost certainly other type material in Brazilian depositories.

Material examined. Paralectotype f: BRAZIL, São Paulo, on Baccharis sp. ( Asteraceae ), 1900, no collector (USNM): 1/1adf (p).

Comment. The single available specimen was in very poor condition and little detail could be seen. Lambdin and Kosztarab (1977) provide a good description. However, on the available specimen, the multilocular disc-pore bands on the posterior abdominal segments appeared to be broad but no pores could be found on segment VII as illustrated by Lambdin and Kosztarab.

The adult female of C. tuberculus is characterised 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 three sizes, all quite small; (iii) larger 8-shaped pores restricted to near stigmatic pore bands; smallest pores on posterior abdominal segments; (iv) cribriform plates present in submedial groups on each side of probably two segments, with 8–16 plates in anterior cluster on abdominal segment III, and 6–9 plates in posterior cluster on segment IV; (v) tubular ducts of two sizes, broader ducts restricted to posterior abdominal segments; narrower ducts frequent elsewhere; (vi) multilocular disc-pores in broad bands across abdominal segments II–VI, but absent from metathorax; (vii) stigmatic pore bands bifurcated; (viii) stigmatic pore bands with abundant spiracular disc-pores, and (ix) leg stubs present.

In the key to adult females of Cerococcus , C. tuberculus keys out close to C. kalmiae from North America.
