Diaphus sp. 2

(Figure 42)

Material: 1 specimen in total. AndaDeVos (1) RGM 962177.

A second 2.6 mm myctophid otolith (OL:OH= 1.34) has shape characteristics of the genus Diaphus . However, it differs from Diaphus sp. 1 by an oval shape with no postdorsal depression and a ventral rim with lobules rather than denticles. Furthermore, the ostium is longer than in Diaphus sp. 1 and slightly widening towards the anterior rim, while the caudal part is shorter. This is reflected in a longer ostium:cauda length ratio (2.5 in Diaphus sp. 2 vs 1.6 in Diaphus sp. 1). More material is needed for proper identification.
