Fig. 10A–D View Fig .

Stratigraphic and geographic range.—Middle Eocene, Lutetian–Bartonian (Auversian) (PB, HB).

Colour pattern description.—The pattern consists of three levels of residual colouration: a dark and homogeneous background, a pale apex and small fluorescent patches ( Fig. 10A–C View Fig ). The small patches are of variable size and shape and present an irregular distribution ( Fig. 10B View Fig 1 View Fig , C). There is doi:10.4202/app.2009.0084

intraspecific variability in the density and coalescence of the patches. The coalescence sometimes produces fluorescent sinuous axial segments ( Fig. 10D View Fig ).
