Amphidromus filozonatus is a species of medium-sized air-breathing tree snail, an arboreal gastropod mollusk in the family Camaenidae.[1]
- Subspecies
- Amphidromus filozonatus filozonatus (E. von Martens, 1867)
- Amphidromus filozonatus jucundus Fulton, 1896
- Smaller than typical filozonatus, the shell appears rather more solid. The body whorl exhibits a grayish-brown color with a yellow band around its lower part, while the upper whorls are white with dark brown stripes that are interrupted by a narrow pale yellow band. [2]
The length of the shell attains 35 mm, its diameter 17 mm.
(Original description in Latin) The sinistral shell is elongate-conical. It presents a somewhat solid structure and a slightly finely striated, glossy surface. The body whorl displays a grayish-brown coloration, adorned with narrow whitish bands (and one black-articulated band). All the upper whorls appear yellowish-whitish, exhibiting blackish, somewhat rhombic spots that are interrupted by a band, with the uppermost whorls being white and the very apex black. The aperture is oblong-ovate, angled below, and brown on the inside, occupying about 2/5 of the shell's length. The peristome feels somewhat thickened and white, showing a shortly reflected lip and a scarcely noticeable parietal callus. The columellar margin appears somewhat straight and dilated.[3]
(Description by H.C. Fulton) The whorls appear less convex than in Amphidromus contrarius. The ground color is either light or dark brown, featuring one or more narrow lighter-colored bands that encircle the whorls, and sometimes displaying a reticulated band at the periphery, which continues at the suture of the upper whorls.[4]
Habitat
