Diaphus aequalis Schwarzhans & Aguilera, 2013

(Figure 43)

2013 Diaphus aequalis Schwarzhans W & Aguilera O , plate 13, figs. 13–25

Material 2 specimens in total: 1 specimen Anda4 RGM 962157; 1 juvenile specimen Anda4 RGM 962344 View Materials .

The adult round otolith has good resemblance with Diaphus aequalis described by Schwarzhans & Aguilera (2013) with respect to its outline (OL=4.0, OH= 3.4 mm), shape of the ostium and cauda of the sulcus (OCL:CCL ratio =1.74), and the denticles along the ventral rim. The thickness of our specimen is slightly less than in the originally described specimens, and the depression posterior of the dorsal angle is more pronounced. Notwithstanding we consider the specimen to match Diaphus aequalis .
