| Abstract |
An impressive, medium-sized new camaenid species, Ganesella tamchuc sp. nov., is described from Hà Nam Province, northern Vietnam. Ganesella tamchuc sp. nov. is similar to Ganesella emma (Pfeiffer, 1863) in its general shell coloration pattern but differs by having a smaller shell size; three distinct color belts on the shell surface, including a white belt at the keel and two dark brown belts situated above and below the keel; strong radial ribs that protrude from the shell surface and also present at the umbilicus and within the aperture; a distinctly keeled last whorl that becomes weak behind the peristome; and a widely open umbilicus through which all whorls are visible. |
