About Conus guanche Lauer, 1993
Description: The shell size of Conus guanche ranges between 22 mm and 55 mm. This is a small shell with a moderately raised spire. Sutural ramps have two light spiral lines, located between the middle of each spire and the suture. Most spires do not have a carena, but in some specimens, especially the spires closest to the apex, the spires are deformed in width and take on a rounded outline. The suture is well-defined and slightly, irregularly wavy. The shoulder is rounded or slightly angulate. The last whorl is conical and slightly convex, with clear growth lines; some of these growth lines are highlighted with brown, which is darker than the shell's base color. Near the base, there are spiral lines spaced well apart from each other, and these are not highlighted by any color. The base background color of these shells is brown. Darker brown longitudinal bands occur on the spires, with lighter bands between them; in some specimens, these lighter bands turn white. A few small brown spots are present on the shoulder. The last whorl is brown, but as described above, some growth lines are marked by brown longitudinal bands that have a darker central line and a slightly wider, slightly lighter outer band. The last whorl has two or three spiral bands that contain lighter, white or nearly white patches, along with brown spiral lines formed by regularly spaced dots. Distribution: This marine species is found in the Atlantic Ocean off the Canary Islands. In 1990, a few unidentified Conus specimens were found at Cala Madonna in Lampedusa, and were later recognized as Conus guanche nitens.
