A single, well-preserved otolith ( Fig. 7I) is attributed, with some reserve, to the Recent Notoscopelus caudispinosus based on the shape of the dorsal rim that is the highest around the middle part of the otolith and on a posteriorly extended posterior part (see also Brzobohatý & Nolf 1996: pl. 7, figs 8–9). This specimen, however, shows a general outline, similar to those of fossil Notoscopelus mediterraneus (Koken, 1891) and Symbolophorus meridionalis Steurbaut, 1979 (see Brzobohatý & Nolf 1996: pl. 8, figs 1–15). Our specimen differs from those of N. mediterraneus by its more extended posterior rim, while otoliths of S. meridionalis show a flatter dorsal rim and a deeper incised excisura. A single specimen of Symbolophorus meridionalis, figured by Lin et al. (2015: fig. 3(7)), shows a much shorter outline, which suggests an attribution to the genus Myctophum Rafinesque, 1810 rather than to Symbolophorus Bolin & Wisner, 1959, and, therefore, this attribution must be considered as doubtful.
