Aegistohadra roemeri

Aegistohadra roemeri is a species of air-breathing land snail, a terrestrial pulmonate gastropod mollusc in the family Camaenidae.

It has been described according to empty shells only.

Description

The length of the shell attains 23.5 mm, its diameter 13.5 mm.

(Original description in Latin) The sinistral shell is perforate, and ovate-conical. It appears somewhat solid and lightly striate, and exhibiting a decussately patterned surface under a lens due to very close spiral striae. Its color is flesh-colored, with a pale band at the suture. The spire is conical, with a rather acute apex. Comprising six scarcely convex whorls, the body whorl almost equals the spire and appears somewhat angled below the middle, displaying two reddish-brown bands and a rounded base. The aperture is oblique and ear-shaped; the peristome is simple, with the outer margin shortly expanded and the columellar margin somewhat vertical, dilated above, and arch-like reflected.

Distribution

Distribution of Aegistohadra roemeri include Phou Kout District within Xiangkhouang Province in Laos and Cambodia.
