- Variety
- Amphidromus xiengensis var. tryoni Pilsbry, 1900: synonym of Amphidromus flavus (L. Pfeiffer, 1861) (junior subjective synonym)
Description
[edit]The shell measures 17–36 mm (0.67–1.42 in) in height and 9–17 mm (0.35–0.67 in) in width.[1]
The sinistral shell is narrowly perforate, elongate, conoid, subfusiform, and glossy. The growth-striae appear very fine on the upper whorls, gradually becoming more prominent on the body whorl, near the aperture. The spire is conic, with a bluish apex; comprising six and a half to seven whorls, the initial two are yellow, while the subsequent ones are ornamented on a light yellow ground with long radial brown and curved flames that are cut in the middle by a narrow yellow spiral zone. The suture is bordered by a narrow yellowish zone below which there is a series of little brown spots. The body whorl features a continuous reddish-brown sutural zone, and on its upper part, a crowded series of brown flames cut by a median yellow spiral; its lower or basal part displays three concentric zones (a yellow one between two brown ones). The aperture is suboval, somewhat angular below, and whitish inside, with the margins joined by a very thin and transparent callus. The columella is thick, rounded, and white; the outer lip appears widely reflexed and white. [3]
Distribution
[edit]Distribution of Amphidromus xiengensis include Sakaeo Province,[4] Chiang Mai Province and Phayao Province in Thailand, Lao Mountains in Cambodia and Champasak Province, Oudomxay Province and Luang Prabang Province in Laos.[1]
