Range: Ryukyu Islands to Philippines; New Caledonia.
Description: Moderately large to large, usually solid. Last whorl narrowly conoid-cylindrical to narrowly ovate; outline convex adapically, less so or straight below. Aperture wider at base than near shoulder. Shoulder subangulate to indistinct. Spire of low to moderate height, outline straight to convex. Larval shell of about 3.5 whorls, maximum diameter 1.1 mm. About first 4 postnuclear whorls tuberculate. Teleoconch sutural ramps flat to slightly concave, with 1 increasing to 4-7 spiral grooves. Last whorl with widely spaced weak spiral grooves at base.

Ground colour white. Last whorl usually overlaid with yellow to orangish brown except for siphonal fasciole and often also area along outer lip of larger adults. Brown bars or blotches fuse into 3 continuous or interrupted spiral bands, at shoulder, above centre and within abapical third. Widely spaced spiral rows of bluish brown to brown dots, dashes and bars extend from base to shoulder, articulated with white and either prominent or obscure within the spiral colour bands. Larval whorls and 3-4 adjacent teleoconch whorls pink. Later ramps with brown radial lines, streaks and blotches, often confluent in latest whorls. Aperture yellow deep within, sometimes completely white (Walls, [1979]).
Habitat and Habits: In 50- 288 m, on or in sand; New Caledonian specimens were dredged in 200- 288 m.
Discussion: C. dusaveli cannot be confused with any of its congeners. It is probably most similar to C. bullatus, which usually has a broader (RD 0.47-0.60) and more ovate (PMD 0.60- 0.74) last whorl, and its colour pattern lacks spiral bands of alternating bluish browns and white markings.

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 Röckel, 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 Röckel, 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.
