Shell of the Week: The Diomedes Mangelia

Continuing with the saga of the large family Mangeliidae, Rubellatoma diomedea Bartsch and Rehder, 1939 reaches about 10 mm (0.4 inch) in length, and has distinctly angled whorls, and a typical “lozenge-shaped” shell. The sculpture includes about 7–10 rounded ribs per whorl crossed by fine spiral striations. The aperture comprises about half the shell length, and the color is white with a couple of broad spiral brown bands more evident on the last whorl.
