Leucosyrinx aequatorialis Thiele, 1925 Fig. 32A Leucosyrinx aequatorialis Thiele, 1925: 182 (216), pl. 23(35) fig. 22. Comitas aequatorialis – Powell 1969: 282 (23-294), pl. 224 fig. 3. Type material Holotype INDIAN OCEAN • off East Africa; 1°48.2′ N, 45°42.5′ E; depth 1644 m; ZMB. Remarks The species is known only from the immature holotype (SL 13 mm). The shell shape, sculpture pattern, and the shape of the subsutural anal sinus fit well within the variability observed in the species of Leucosyrinx as defined here. The lack of the nodules on the shoulder of the last whorl is a character found in different species of Leucosyrinx. Given that the anal sinus shape aligns more closely with species of Leucosyrinx than with Comitas, we propose transferring the species to the former genus. Distribution Known only from type locality.
