Fig. 9A–H View Fig .
Stratigraphic and geographic range.—Middle Eocene, Lutetian (PB).
Colour pattern description.—This species show three levels of residual colouration: a dark and homogeneous background, a pale apex and fluorescent rows of small axial coalescent segments. These fluorescent and thin segments very close to each other form small zigzags and are more or less elongated. Their width is not constant ( Fig. 9B View Fig 2, F 2, G 2 View Fig ). The coalescence produces, on the subsutural step, broad triangular fluorescent patches. The segments are often opisthocline and the frequency of the zigzags varies among individuals ( Fig. 9B View Fig 2, C, G 2, H 2 View Fig ).
