Two new species are added to the genus Armstrongium (dlinza and carolinae). The genera Silvanidium, Silvanidiella, Pondoidium, and Parasilvanidium are treated as subgenera of Eremidium. The nominal subgenus Eremidium (Eremidium) appears to be comprised of five species groups, here called Group A through E. The subgenus E. (Silvanidium) is considered to included only the type species, E. (S.) armstrongi (Brown). Of the three species previously placed under Silvanidium, aculeatum Brown and peninsulare Brown are moved to Silvanidiella and margaretae Brown is moved to a new subgenus Natalium. Pondoidium trilineatum Brown is placed under Eremidium (Pondoidium). The subgenus Eremidium (Eremidium) now includes 21 species, of which two are new. The subgenus Eremidium (Silvanidiella) presently includes 17 species, of which 11 are new. The subgenus Eremidium (Pondoidium) presently includes 10 species, of which 4 are new. The subgenus Eremidium (Parasilvanidium) presently includes one species, previously placed under Parasilvanidium.

A new genus Zulutettix is described to include 4 new species: unicornis, entumeni, hluhluwe, and tarranti.
