  Conus sculpturatus Röckel & da Motta, 1986.

Range: Samar and Marinduque, Philippines.

Description: Moderately small to medium-sized, moderately light to moderately solid. Last whorl conical to narrowly conical, sometimes narrowly conoid-cylindrical to ventricosely conical; outline variably convex, straight (right side) and concave (left side) basally. Shoulder carinate. Spire usually of moderate height, outline concave. Larval shell of 2.5-3 whorls, maximum diameter about 0.8 mm. First 2-3 postnuclear whorls weakly tuberculate. Teleoconch sutural ramps flat to slightly concave, with 1 increasing to 6-8 spiral grooves. Last whorl with strong spiral ribs and pairs of ribs, often weakly granulose; intervening grooves with axial threads crossed by weak spiral striae or threads.

Shell Morphometry
  L 32-44 mm
  RW 0.08-0.12 g/mm
  RD 0.48-0.52
  PMD 0.78-0.90
  RSH 0.12-0.17

Ground colour white. Last whorl with irregularly arranged brown dashes and dots on spiral ribs and in grooves between, often fusing in axial streaks or blotches, and in 2 interrupted spiral bands. Larval whorls white, sometimes grading to light beige. Early postnuclear sutural ramps immaculate beige; following ramps white, with brown radial streaks and blotches. Aperture white.

Habitat and Habits: No information.

Discussion: C. sculpturatus resembles C. alabaster, which differs in its broader last whorl (RD 0.52-0.58), larger number (3-6) of tuberculate early whorls, rather flat late sutural ramps, and in its white to sparsely maculated last whorl and spire. C. asiaticus also has a broader last whorl (RD 0.53-0.59), more (3-6) tuberculate early whorls and a less prominent colour pattern. C. mucronatus also differs in having a broader last whorl (RD 0.52-0.62); it has a sharply angulate rather than carinate shoulder, generally weaker spiral selpture on the adapical part of the last whorl and prominent brown spiral lines on the last whorl. C. laterculatus can be distinguished by its angulate to sharply angulate rather than carinate shoulder, straighter spire outline and smaller number of spiral grooves (4-5) on the late sutural ramps; its last whorl is sculptured with ribbons rather than ribs and has straight rather than concave left side basally; its aperture is bluish-violet.

This section contains verbatim reproductions of the accounts of 316 species of Conus from the Indo-Pacific region, from Manual of the Living Conidae, by Rckel, Korn and Kohn (1995). They are reproduced with the kind permission of the present publisher, Conchbooks.

All plates and figures referred to in the text are also in Rckel, Korn & Kohn, 1995. Manual of the Living Conidae Vol. 1: Indo-Pacific Region.

The range maps have been modified so that each species account has it own map, rather than one map that showed the ranges of several species in the original work. This was necessary because each species account is on a separate page on the website and not confined to the order of accounts in the book.
