The cranidial anterior border broadens, particularly the lateral sections across the palepebro-ocular ridges, and develops a slight median point; the glabella tapers anteriorly; LF narrows; the axial furrows broaden; and sculpture becomes slightly finer. Librigenae elongate slightly; the field widens and its pits enlarge; and the lateral border furrow deepens. The thorax is not sufficiently well known to discuss segments ontogeny. Pygidial changes are not well represented in the available specimens. However, the pygidium overall elongates, the terminal piece becomes narrower and longer, and the tubercles on the pleurae near the axis disappear.
