Lophophaena buetschlii

Taxonomy

Catalog entries: Lithomelissa buetschlii

Original description: Shell smooth, with slight collar stricture. Relative length of the two joints = 5: 6, breadth = 4: 5. Cephalis ovate, large, with two small conical horns, which are opposed nearly horizontally, in the upper part of the cephalis; an anterior frontal and a posterior occipital horn. Thorax ovate, truncate, little larger. Pores of both joints irregular, roundish, of very different sizes. From the middle part of the thorax there arise three short conical divergent feet. (In the figured specimen there were some accessory thorns; in another specimen, found afterwards, the surface was quite smooth, but the two horns and the three feet much larger, half as long as the cephalis.)
Remarks on original description: Haeckel listed Lithomelissa bütschlii under the subgeneric name Micromelissa, but did not include the subgeneric name in the species name. This species is assigned to Micromelissa (the junior homonym) Haeckel, 1887a (non Haeckel, 1881a) and the Sethomelissa (the junior homonym) Haeckel, 1887a (non Haeckel, 1881a).
