Type material

Holotype INDIAN OCEAN • 1 spec., SL 32.0 mm; Gulf of Oman; 24°49′ N, 56°56′ E, 225 ftm (= 411 m), NHMUK 1905-7-14 -49.

Remarks

The species is known only from the holotype. There are no sequenced species of Leucosyrinx that resemble L. halicyria . We attribute it to the genus with some doubts, but remove it from Comitas on the basis of the shape and position of the subsutural anal sinus, occupying the entire subsutural ramp, like in other Leucosyrinx spp.
