( Fig. 13 A-D) TYPE MATERIAL. — Holotype :MONTROUZIER expedition, stn 1269, New Caledonia , Doiman Reef , Touhou Sector , 20°35.1’S , 165°08.1’E , 15-20 m , diving team, IX.1993 , 1 specimen ,H 3.2, D 5.1 mm ( MNHN 24772 , Fig.13 A-D). TYPE LOCALITY. — New Caledonia , Doiman Reef. DISTRIBUTION. — Known only from holotype . ETYMOLOGY. — After the Latin noun, “splendidus”. DESCRIPTION Male shell ( Fig. 13 A-D) Whorls 3.3; profile moderately high for genus; peripheral angulation high on whorl, shoulder ramp nearly flat above, profile below shoulder evenly rounded. Axial sculpture of strong ribs, 33 on last whorl; spinose and projecting in early whorls, spinosity much diminished in final third whorl. Spiral sculpture of single strong, low cord on shoulder in early whorls, changing to three narrow cords in final ⅓ whorl; base with strong subtending cord, and three cords of nearly equal strength between peripheral cord and subtending cord. Base with deep pits on outer side of subtending cord and other basal cords. Umbilicus bordered by broad, angular emergent cord, overridden by narrow axial ribs; umbilicus partially open, partially obstructed by emergent tongue of lip; tongue extending forward of plane of aperture. Final lip massive, extending for ⅓ of final quarter whorl, showing about twenty successively decreasing layers of deposition, lip conforming to spiral sculpture; tongue extending half the diameter of aperture on previous whorl, showing similar layers of deposition decreasing in extent; plane of aperture coinciding with umbilical wall. H 3.2, D 5.1 mm ( holotype ). Female shell Unknown. Operculum Unknown. REMARKS This species is characterised by the moderately large size, high count of axial ribs, its strongly developed clathrate sculpture, and in having the tongue out of alignment with the plane of the aperture, projecting strongly forward of the aperture so that it does not block the open umbilicus. Although the umbilicus is open, access to the umbilicus is blocked, so this is not a female shell. The closest comparison is with L. magna n. sp. ( Figs 8 ; 9 ), which is larger and has the apertural tongue pointed along the plane of the aperture and the coiling axis, rather than projecting forward.
