Species / Dolomena Hickeyi


Original Description of Strombus (Labiostrombus) hickeyi by Willan, 2000:

  • "Shell to 55 mm in height. Shell solid and moderately heavy. Spire tall, consisting of 9 whorls; uppermost 6 teleoconch whorls with numerous evenly rounded axial plicae; remaining 3 whorls with stronger plicae (approximately 22 on the penultimate whorl) that are heavily nodulose on the shoulder, thus rendering the whorls strongly shouldered. All whorls (except the body whorl) bear fine spiral striae between the plications (approximately 15 on he dorsal side of the penultimate whorl); 2 strong striae typically present immediately below the suture. Body whorl smooth except for the striae, spiral ridges encircle the anterior canal are present on the outside of the outer lip. Varizes present on the spire whorls. Body whorl bears 3-5 strong nodules at the shoulder on the dorsal side (strongest near the mid-dorsal midline); the nodules are absent past the mid-dorsal line and on the outer lip. The ventral side bears only weak nodules or the nodules are amalgamated into a keel through secondary calcification (as in the holotype). Outer lip expanded into broad, secondarily calcified flange. Aperture two-thirds the height of the shell. Columella with secondary callus throughout its length, callus thicker medially. Callus bearing irregular lirate rugae on the adapical section and 7-10 weak denticles on the abapical section, the upper denticles more widely spaced. Siphonal canal recurved. Stromboid notch relatively deep, with the anterior canal extending a short distance beyond the outer lip. Posterior sinus very shallow. Posterior canal prominent, deep and narrow, extending obliquely across the penultimate whorl, to which it is attached, to reach the shoulder of the penultimate whorl. The termination of the posterior canal can be reflected towards the apex. Colour: Protoconch and first two teleoconch whorls uniformly lilac. The following 2 or 3 teleoconch whorls lilac with a wide, brown subsutural band. Remaining whorls cream to buff with numerous, dense chocolate brown, purple, cream, yellow or orange markings forming spiral bands. In addition some darker spiral bands are present, especially on the presutural ramp on the body whorl where they intensify into a series of brownish flames. The spire and the dorsum are typically more suffused with colour than the ventral side. Thenodules are white. The aperture is porcelain-white, and there is a pale purple-brown stain far inside the outer lip. This dark staining is interrupted by a narrow, white patch three-quarters of the distance up the aperture. The columella callus is completely white. The periostracum is thin, pale brown and translucent. Operculum one-third the length of the aperture, narrow andelongate, with 7-10 stout spines on the outer edge. Animal unknown.

Locus typicus: Dingo beach, Gloucester Passage, central Queensland State, north east Australia (20°04'S, 148°28'E)

Habitat: sandy substrates interspersed with patches of algae and/or seagrass. Its depth range extends from low intertidal to 16 m (Willan, 2000)

Etymology: named after Andrew Hickey of Proserpine, Queensland State
