Original description Diagnosis of the genus. Test free, composed of a rounded proloculus and a second tubular chamber. The coiling is planispiral to slightly trochospiral, so the test usually develops a lower slightly concave part and an upper slightly convex part, with some irregularities. The wall is two-layered, with an inner microgranular layer and an outer fibrous layer covering all whorls. This thin fibrous layer separates the successive whorls, and in the umbilical area it covers the side of the micro- granular layer, not filling this area. The main aperture is simple, located at the end of the tubular chamber. Secondary apertures are present along the sutures between the whorls, in the upper part of the test.
Stratigraphic distribution. Planohowchinia is confined to zone 15, V3bα-β or Cf6α-β (late Viséan) of the Guadiato-Guadalmellato area, as the single species described in the genus. It is regarded as a taxon endemic to southwestern Spain.
