Original Description
Primärschale und erste Tertiärschale, manchmal auch die zweite Tertiärschale, genau wie bei Arachnosphaera myriacantha, erstere also mit hexagonalen Poren, letztere mit polygonalen. Die zweite bzw. dritte Tertiärschale liefert verzweigte Stacheln, welche mit den Verzweigungen des dritten bzw. vierten Quirls ein sehr loses Netzwerk bilden.
[Primary and first tertiary shells, and sometimes the second teriary shell, similar to Arachnosphaera myriacanth, first shell with hexagonal pores, last with polygonal pores. Second tertiary shell related to the third by ramified spines that build a loose network with the apophyses originating from the spines between the third and fourth shells. (In German. Translated by J.P.C.)]

Primary shell diameter 90µm; intervals between tertiary shells 40µm, 40µm and 50µm. Total diameter 450 - 500µm.
