TYPE SPECIES. — Kalimnasphaera maculosa Webby & Blom, 1986 ( Webby & Blom 1986: 152, fig. 3.4-3.9, 4.1-4.8).

AGE AND LOCATION OF TYPE MATERIAL. — Upper Ordovician, Malongulli Formation, central New South Wales, Australia.

TAXON CODE. — 263.

STATUS. — Valid.

DIAGNOSIS. — “‘Palaeoactinommid’ with two delicate inner, reticulate medullary shells, a strong reticulate and pylomate cortical shell (both medullary and cortical shells composed of pore bars), and a loosely fenestrate outer shell, this latter preserved in varying degrees of completeness. Three to six long, gently tapering buttressed main spines arise from cortical shell. Radial beams cross spaces between medullary and cortical shells, but do not extend inwards, beyond medullary shells. Numerous By-spines occupy space between cortical and outer fenestrate shells. Outer shell is only complete in areas where lateral spinules are Iinked to by-spines and main spines.” ( Webby & Blom 1986: 152).
