CATALOGUE OF RECENT AND FOSSIL CONUS

  Conus pseudokimioi da Motta & Martin, 1982.

Range: Only known from the type locality.

Description: Small and light. Last whorl conical to slightly pyriform; outline straight to convex adapically, straight to concave below. Shoulder angulate. Spire low, outline concave. Larval shell of about 3 whorls, maximum diameter about 1 mm. First 1-3 postnuclear whorls tuberculate. Teleoconch sutural ramps flat, with 1-3 increasing to 4-7 spiral grooves. Last whorl with fine, variably spaced spiral ribs at base and about 6 fine spiral grooves below shoulder.

Ground colour light greyish violet. Last whorl encircled with about 20 fine brown spiral lines and with light brown axial streaks and rectangular blotches forming an interrupted spiral band at centre. Larval whorls grey. Postnuclear sutural ramps with evenly spaced brown radial blotches extending over shoulder, darker at their outer margins or reduced to marginal dots in early whorls. Aperture violet.

Habitat and Habits: In 120-240 m.

Discussion: C. pseudokimioi was described as a subspecies of C. kimiioi. We provisionally favour the status of a separate species for C. pseudokimioi, because C. kimioi differs in its narrower last whorl (RD 0.46-0.54) with a regular "brick wall" pattern and a concave rather than convex outline adapically; its shoulder is carinate rather than angulate and its larval shell slightly darker, slightly narrower and of slightly more whorls than that of C. pseudokimioi. C. spirofi1is. can be distinguished by its broader last whorl (RD 0.63-0.75). generally higher spire (RSH 0.14-0.22), and the absence of spiral grooves on its sutural ramps; its last whorl may have spiral ribs rather than fine spiral grooves below the 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.
