Leiorhagium clandestinum sp. n.

Type material.

Holotype MNHN IM 2000-27865; paratypes MNHN IM 2000-27866 (3).

Etymology.

The Latin adjective clandestinus means clandestine and refers to the new species’ external identity with Leiorhagium kavuneva .

Diagnosis.

Leiorhagium clandestinum sp. n. is most similar to Leiorhagium adioincola sp. n. and Leiorhagium kavuneva . For the distinction from Leiorhagium adioincola sp. n. see above. Due to the lack of anatomical data, Leiorhagium clandestinum sp. n. and Leiorhagium kavuneva can only be distinguished based on 7.6% average sequence divergence of COI (p-distance).

Shell.

Pupiform, 1.86 times higher than wide, 4.25-5 whorls, without colour, transparent; protoconch very faintly pitted with c. 1 whorl; palatal denticle a small droplet 1/8 whorl behind outer lip; aperture as high as wide (Figs 2D, 3G, 4G, H).
