Anguispira rugoderma, also known as the Pine Mountain tigersnail, is a rare, narrow-ranged species of pulmonate land snail in the family Discidae, the disk snails. It is named after the Pine Mounatin ridge, a section of the Appalachian Mountains that overlaps with the snail's range.[1]
The Pine Mountain tigersnail is visually similar to its close relative Anguispira alternata. However, its shell is larger, its markings are less prominent, and its umbilicus is wider than alternata's.[2][3] The shell ranges from 21 to 30 mm (0.83 to 1.18 in) in width and 12.5 to 16.4 mm (0.49 to 0.65 in) in height. It has strong ribs which extend over the periphery and into the umbilicus, giving the shell a slightly wavy appearance.[4] The snail's appearance is defined by irregular brown splotches that radiate outwards across the entirety of the shell.[3]
