Miniaceoliva lamberti chloeae (Petuch & Myers, 2014) Empty Miniaceoliva lamberti chloeae (Petuch & Myers, 2014)

Sam 17 Mai 2014 - 1:29
Voici la fameuse Olive de wallis... qui portera désormais un nom.....
Cette Olive par sa forme m'a toujours intriguée, j'en avais envoyé quelques exemplaires à Edward Petuch qui en a conclu qu'il s’agissait bien d'une nouvelle forme....


Miniaceoliva lamberti chloeae (Petuch & Myers, 2014) 2014-012


Description: Shell of average size for genus, bulbous and inflated, thickened and heavy, with rounded profile and sides; spire proportionally low, only slightly elevated, subpyramidal; shoulder rounded, grading directly into spire; spire whorls partially callused; filament channel proportionally wide and deep, edged by outwardly-bending, sharp-edged carina; fasciole and fascicular band narrow, confined to anterior one-fourth of body whorl; base color pale cream-orange overlaid with densely-packed reticulated network of olive-green longitudinal flammules, thin patches, and elongated spots; flammules of reticulated pattern bordered by large patches of sky blue and dark orange, which often completely fill areas between olive-green flammules; 3 wide bands of large dark blue-green rectangular patches, one around shoulder, one around mid-body, and one around anterior tip, present on some specimens (such as paratype in research collection of senior author); shoulder area devoid of fine reticulated pattern, being marked by large orange triangular patches; base of filament channel along shoulder marked with evenly-spaced small blue-green dashes; spire whorls dark olive-green, overlaid with closely-packed amorphous patches of orange and blue; upper edge of filament channel carina white; columella orange, ornamented with 19-22 large, elongated, evenly-spaced, tooth-like plications; anterior tip of columella darker orange; fascicular band dark purple-brown in color, with pattern composed of fusion of numerous small flammules; aperture proportionally wide, flaring, slightly arcuate, becoming wider toward anterior end; lip thickened, arcuate in profile, colored bright orange; interior of aperture intense deep red orange; early whorls white; protoconch white in color, composed of 2 whorls.

 
Type Specimens: Holotype: length 61 mm, width 30 mm, MNHN IM-2000-27480 (in the molluscan type collection of the Department of Malacology, National Museum of Natural History, Paris, France); Paratypes: length 60 mm, width 37 mm, in the research collection of the senior author; length 60 mm, in the collection of Thierry Vulliet, Queensland, Australia.
 
Type Locality: In sand, 3 m depth off Tepako Point, Uvea Island, Wallis and Futuna Islands.
 
Range: The new subspecies ranges from Wallis and Futuna in the east, westward to the Fijis, Vanuatu, and Santa Cruz Islands of Melanesia.
 
Etymology: Named in honor of Chloe Gutierrez-Vulliet of Gold Coast, Queensland, Australia, grand-daughter of well-known conchologist Thierry Vulliet.

Discussion: As outlined at the end of the previous description, Miniaceoliva lamberti chloeae represents a distinct, geographically-isolated subspecies of the Coral Sea M. lamberti lamberti (Jousseaume, 1884) (Figure 2C, D). The new subspecies represents the easternmost extension of the M. lamberti complex and abuts against the ranges of the M. efasciata (Dautzenberg, 1927) complex; with M. efasciata efasciata to the east, in Samoa and the Cook Islands, and with M. efasciata thierryi new subspecies to the north, in Kiribati. The new subspecies differs from its Coral Sea-centered nominate subspecies to the west in having a far more inflated and bulbous shell shape, in being a more darkly-colored shell, with a densely reticulated pattern of olive-green, blue, and orange flammules and spots, in having a bright orange anterior end to the columella, and in having a much more colorful interior of the aperture, being a vivid deep orange-red instead of the pale orange seen in M. lamberti lamberti.
