Original Description

Schale mit regelmäßigen sechseckigen Maschen, diese fünfmal so breit wie die Gitterbalken. Etwa 16-20 Hauptstacheln, dreikantig, drei Viertel so lang wie der Radius, breit und kräftig, pyramidal. Nebenstacheln dornig, höchstens ein Drittel so lang wie die Hauptstacheln, zu vielen über die Schale verteilt.

Translation:

Shell with regular hexagonal meshes, five times as wide as the lattice bars. About 16-20 main spines, triangular, three quarters as long as the radius, broad and strong, pyramidal. Secondary spines thorny, at most a third as long as the main spines, numerously distributed over the shell.

Size:

Schalendurchmesser 0,115 mm, Porendurchmesser 0,01 mm, Gitterbalken 0,002 bis 0,003 mm, Hauptstacheln lang 0,046 mm, Nebenstacheln lang 0,01 mm, Hauptstacheln breit an der Basis 0,015 mm.
1 specimen. Shell diameter 0.115 mm, pore diameter 0.01 mm, lattice bars 0.002 to 0.003 mm, main spines long 0.046 mm, secondary spines long 0.01 mm, main spines wide at the base 0.015 mm.

Extra details from original publication

Distinguishing characters: Die Art steht Heliosphaera hexagonaria H. am nächsten, ist aber nur halb so groß und hat höchstens 20, nicht 40 Hauptstacheln. Die Gitterbalken sind bei Heliosphaera radiata viel kräftiger und die Hauptstacheln länger.
Von Heliosphaera octacantha Mast ist sie durch die größere Stachelzahl und den kleineren Schalendurchmesser unterschieden.

The species is closest to Heliosphaera hexagonaria H., but is only half the size and has at most 20, not 40, main spines. The lattice bars in Heliosphaera radiata are much stronger and the main spines are longer. It is distinguished from Heliosphaera octacantha Mast by the larger number of spines and the smaller shell diameter.
