Myctophum selenops Tåning, 1928

(Figure 58)

2013 Schwarzhans W & Aguilera O, p. 103, plate 3, fig. 21

Material: 1 specimen in total. Anda2 (1) RGM 962207.

The specimen has an equal length and height (OL:OH ratio 1.01), a rather rounded dorsal rim with a blunt predorsal angle and a slight postdorsal depression. The ventral rim is bent most strongly in its middle part, by which an extended ventral area is generated. The sulcus has a clear crista superior that makes an angle at the ostium-cauda transition. The ostium runs upwards toward its opening, while the colliculum of the cauda broadens at its posterior side, making it bend upwards. These properties meet the characteristics of the extant Myctophum selenops .
