Leptochiton kantori Sirenko 2016: 53 View in CoL , figs 172–204.

Type material. Holotype ( MNHN IM-2000-31608 ) and 3 paratypes ( MNHN IM-2000-31609 - 31610 , MNHN-IM- 2007-17439).

Type locality. Vanuatu, 14°50’S, 167°03’E, 605–723 m. GoogleMaps

Material examined. Holotype and paratype; Philippines. PANGLAO 2005, Bohol / Mindanao Sea , stn CP2361, 8°53.1’N, 123°33.5’E, 516-543 m, 1 spm (MNHN-IM-2000-35505), BL 5.1 mm, 26.05.2005 GoogleMaps .

Distribution. Off Vanuatu (605–723 m), the Solomon Islands (229–236 m) and the Philippines (516–543) (herein). The new records expand the distribution for this species to the north.

Remarks. The studied specimen (MNHN-IM-2000-35505) is similar to the type specimens except of the sculpture of the tegmentum of the head valve and the lateral areas of the intermediate valves which have granules (vs. lacking granules in L. kantori ). The specimen from the Philippines possesses four gills on each side and a radula that is 1.5 mm long with 37 transverse rows of mature teeth. Each granule of the tegmentum in the studied specimen has five pores of aesthetes. The studied specimen is superficially similar to L perscitus Kaas, 1991 , but differs in possessing four gills (vs. six gills in L. perscitus ), longitudinal rows of granules on the central areas of intermediate valves (vs. granules arranged quincuncially in L. perscitus ), and a tridentate head of the major lateral teeth of the radula (vs. unidentate head in L. perscitus ).
