CATALOGUE OF RECENT AND FOSSIL CONUS

  Conus bondarevi Röckel & Raybaudi M., 1992.

Range: N. Somalia.

Description: Moderately small to medium-sized, moderately solid. Last whorl conical to broadly conical; outline convex below shoulder, straight below. Shoulder angulate. Spire low, outline sigmoid to concave. Larval shell of about 2 whorls, maximum diameter 1.0-1.2 mm. First 2.5-4 postnuclear whorls weakly tuberculate, late whorls broadly carinate. Teleoconch sutural ramps flat, with 2 increasing to 3-4 spiral grooves; latest ramps may have additional spiral striae. Last whorl with distinct spiral ribs on basal fourth to third.

Shell Morphometry
  L 29-41 mm
  RW 0.12-0.25 g/mm
  RD 0.61-0.72
  PMD 0.86-0.89
  RSH 0.07-0.12

Ground colour white, sometimes suffused with vale orange or violet. Last whorl with a broad yellow, orGge, red or brown spiral band on each side of centre, occasionally with a narrow third band below shoulder. Ground-colour zone sometimes narrow and obsolete at shoulder. Base white to orange. Larval whorls white or yellow, orange or violet. Postnuclear sutural ramps shaded and radially spotted with same colours as last whorl. Aperture white to pale purple, slightly translucent.

Habitat and Habits: Reported from about 150 m.

Discussion: C. bondarevi resembles C. daucus Hwass from the W. Atlantic in colour pattern and shape; for comparison, see the Discussion of C. daucus (Vol. II). Sympatric C. namocanus attains larger size (L 40-100 mm), has a greenish yellow apex with 2.5-3 larval whorls and with tubercles only in the first 1-1.5 postnuclear whorls, its latest sutural ramps have an obsolete spiral sculpture and the outer margins are not carinate. The last whorl of C. namocanus is predominantly olive, and its pattern usually includes spiral lines and its aperture is bluish violet. The syntypes of C. incarnates (Appendix 1, no. 14; Pl. 71, Figs. 3-5) are larger than adult C. bondarevi (L 47-65 mm), have subangulate shoulders and generally higher spires, and their late sutural ramps bear twice as many spiral grooves but lack carinate outer margins.

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.
