Amphidromus roseolabiatus is a species of terrestrial gastropod in the family Camaenidae.^[1]

Distribution

Distribution of Amphidromus roseolabiatus includes central and northern Laos, Nan Province in Thailand and Phong Nha-Kẻ Bàng National Park in Vietnam.^[2] Found in Karimganj District, Bazaricherra, Assam, India.

Description

The shell measures 24–42 mm (0.94–1.65 in) in height and 13–22 mm (0.51–0.87 in) in width.^[2]

(Original description) The sinistral shell is ovate-conic, moderately umbilicate, and relatively solid. It consists of 6.75 slightly convex whorls, with a barely discernible peripheral angulation. The upper whorls are white, transitioning to pale lemon on the lower whorls, which are marked by close-set, oblique light green lines. The shell exhibits spiral striations. The outer lip and the columella are pink and expanded, with the lip slightly reflected. The aperture's interior is white. ^[3]

(Redescription) The shell is medium in size. It exhibits chirality dimorphism, and presents an elongate to ovate conical shape that is rather thin and glossy. The spire appears conical; the apex is acute and light brown, lacking a black spot on its tip. Comprising six to seven nearly smooth whorls, the shell displays a wide and depressed suture, and the body whorl is rounded. The periostracum is usually deciduous, sometimes showing yellowish-green radial streaks that appear more conspicuous on the body whorl and faded on earlier whorls. The body whorl features a thin, whitish subsutural band and may or may not have a reddish-brown spiral band on the periphery, though this band usually does not reach the apertural lip; a varix is absent. The parietal callus is thin and transparent. The aperture is ovate to elongate; the peristome is expanded and not reflected; the lip is usually purplish-pink. The columella is straight, thickened, and purplish-pink. The umbilicus is narrowly opened. ^[4]
