M a t e r i a l. One fragment of librigena (PCZCU 2291) and one fragment of cranidium (PCZCU 2295).

R e m a r k s. The studied and figured fragment of librigena is unfortunately so fragmentary that it does not enable any exact affiliation. It is tr. vaulted in cross-section, with a wide inflated anterolateral margin possessing 4–5 fine ridges; the anteriormost three are almost sub-parallel with the margin, the remaining two have a rather irregularly undulating course. The anterolateral border furrow is wide, moderately deep, rather discontinuous, interrupted by inconspicuous finger-like anterolateral projections of the librigenal field. No traces of tropidium on the librigenal field. The eyes (broken off) are large, a sub-ocular groove is present. The surface of the free cheek is smooth, posterolateral border (mostly broken off) with fine short striation sub-parallel with the posterior border.

O c c u r r e n c e. UDI, sample TM 12.
