Original Description

Schalenlänge 2: 3. Mündungsöffnung ein glatter runder Ring halb so weit als der grösste Breitendurchmesser. Die Gitterlöcher des zweiten Gliedes sind in schrägen alternirenden Reihen sehr regelmässig angeordnet und zählt man 7; die Zwischenbalken noch ein mal so breit.
[Urna-shaped shell; cupola-shaped first segment with short spines on the top. Second segment as an inflated ellipsoid 4 times as long as the first segment; diameter ratios on the total length as 2: 3. Opening with a smooth circular peristome half as broad as the largest diameter. Pores on the two segments distributed in 7 very regular oblique alternating rows; bars between pores twice as large. (Translation from German by J.P.C.)]

Length of the shell 90µm, big diameter 60µm, opening 30µm; length of the first segment 16µm, of the apical spines 7µm, of the second segment 70µm. Pores 3µm, bars 6µm.

Editors' Notes
[Figure: Stohr in this work reverses the figures for Lophophaena amphora and Petalospyris radicata. The figure identified as Lophophaena amphora (fig.18) in fact illustrates Petalospyris radicata and is included with the latter species. The figure identified as Petalospyris radicata (fig.11) in fact illustrates Lophophaena amphora and is included here.
