Rapa sp. cf. R. incurva ( Dunker, 1852) View in CoL
( Figs 11 View FIG C-E; 12E)
Bulbus incurvus Dunker, 1852: 126 .
TYPE MATERIAL. — Rapa incurva : Holotype ( ZMB 103.967 View Materials ).
TYPE LOCALITY. — Bulbus incurvus: Uncertain : “ China?” [no locality given on label of the holotype].
MATERIAL EXAMINED. — The type material of R. incurva and:
Banc Président Thiers, BENTHAUS, stn DW 1926, 24°38.2’S, 146°00.8’W, 50-90 m, 1 juv dd, 1 juv lv ( Figs 11 View FIG C-E; 12E).
DISTRIBUTION. — Rapa incurva : Pacific Ocean,from the Kii Peninsula, Japan, “intertidal to 20 m, in base of soft corals” ( Higo et al. 1999: 221). From New Caledonia and Loyalty Islands, empty shells in 20 m, alive in 17- 31 m.
REMARKS
Protoconch of 3.7 whorls, 710 µm high and 730 µm wide at the base. Protoconch I of 0.8 whorls covered by pustules. Protoconch II of about 2.9 whorls, with 2 major spiral keels (the abapical starting on the early second protoconch whorl, the adapical starting at the end of the second protoconch whorl), and one minor subsutural keel, sculptured with a series of threads over each keel. Spiral microsculpture evident on the keels.The specimens of the present material, are somehow different from juveniles of Rapa incurva in having a more spherical shape. It is possible, similarly to what happens in Leptoconchus , that also Rapa includes cryptic species of difficult morphological interpretation.
