Material examined (sequenced)

SOCIETY ISLANDS • 1 lv; Bora Bora ; 16°32′ S, 151°48′ E; 798–830 m; TARASOC, stn CP3419; MNHN-IM-2007-38671 • 1 lv; between Raiatea and Tahaa; 16°43′6″ S, 151°25′ E; 800 m; TARASOC, stn CP3439; MNHN-IM-2007-38723 .

DNA diagnosis (based on 2 cox 1 sequences)

No sufficiently robust diagnosis for this species could be retrieved.

Remarks

The species is represented in our material by two rather different in shell outline medium-sized specimens (up to 30.8 mm) with nearly identical cox 1 sequences. This is the only presently known species of Leucosyrinx from French Polynesia.

Species of Leucosyrinx known only from empty shells
