Type material

Holotype

INDIAN OCEAN • Nicobar Is.; 7°48′ N, 93°07′ E; depth 805 m; whereabouts unknown.

Remarks

This species is based on a single strongly damaged holotype (SL 24 mm). The original drawing and the details of the sculpture provided by Thiele (1925) show a subsutural row of rounded knobs. These are not found in any species of Leucosyrinx , but are, conversely, present in all species of Sibogasyrinx and Comispira . Based on the broadly-spaced and rather strong spiral cords, we attribute the species to Comispira .
