Description
Original diagnosis after Ginter & Hansen, 2010 [26471]: A species of Denaea characterised by teeth with the following combination of features: in seven-cuspid teeth, the second to the outermost pair of the lateral cusps is the highest; the central cusp is circular in cross section, and curves markedly linguad with only slight sigmoid flexure; the cristae on the cusps are delicate, subparallel, extend from the base to the tip and generally do not converge; the cristae are equally spaced both labially and lingually and the lateral carinae are absent; the base does not have a distinct button, but only a vague thickening or hump on the oral-lingual side; the openings of the main basal canals on the lingual rim and in the centre of the oral surface of the base are relatively large.
