Original Description Lophophaena which is very close to the Paleogene representatives of the genus (fig. 56, XIII). The lateral lobes are clearly expressed as "neck" inflations. The lower part of the II segment is cylindrical. The ratio of the widths of segments I and II equals 1:1.3. The rounded, densely spaced pores on both segments are of an equal size. Their diameter does not exceed more than 1.5-3 times the width of the septa between them. Spines D, Lr and Ll yield considerably long terminal feet, whereas the secondary apophyses of the margin of the shell (radial appendages) are not expressed. There are no long filarnentous spines on the I segment, but merely short spines instead, which are specifically developed in the area of the "neck". These short spines can merge with the apophyses and form an outer net which envelopes the "neck". (In Russian. Translation via W.R. Riedel)
(Based on 12 specimens) Length of I segment (without "neck") approximately 30µm, width 30-35µm; length of II segment 60µm and over, width 50-55µm. Distinguishing characters (rw): Differs from Lithomelissa laticeps, described by Jørgensen, in the distinctly developed "neck", which is separated from the thorax by arches cp and pp. The species has been named in honour of P. T. Cleve, the first scientist to discover this species. Editors' Notes Bipolar: Nowegian Sea, Arctic and Antarctic.
