Range: New Caledonia and Chesterfield Is.

Description: Medium-sized, moderately solid to solid. Last whorl ventricosely conical; outline slightly convex. Shoulder angulate. Spire of low to moderate height, outline concave. Larval shell of about 3 whorls, maximum diameter about 0.8 mm. First 5-6 postnuclear whorls tuberculate. Teleoconch sutural ramps flat, concave in last whorls, with 2 increasing to 5 spiral grooves gradually disappearing on last ramps. Last whorl smooth except for a few spiral ribs near base.

Ground colour white. Last whorl with10-20 spiral rows of orange to reddish brown blotches alternating with white. Larval whorls and adjacent 2 teleoconch sutural ramps white. Following ramps with brown radial blotches. Aperture white.

Periostracum light brown, thin, translucent.

Habitat and Habits: In 70-415 m.

Discussion: C. richeri resembles C. timorensis and C. floccatus. C. timorensis is lighter (RW 0.07-0.22) and its last whorl is more cylindrical in outline. C. floccatus differs mainly in its last whorl colour pattern dominated by brown blotches, flecks, flames and axial streaks; these features are not present in C. richeri. C. floccatus also has a lower spire (RSH 0.07- 0.15) and a less angulate shoulder.

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.
