Description
Holotype: Shell height 3.59 mm, shell width 1.91 mm. Aperture height 0.93 mm, aperture width 1.86 mm. Shell width/shell height ratio = 0.53. Aperture width/aperture height ratio = 1.15 (Fig. 2 View Figure 2 A).
Paratypes: Shell height 3.59-4.35 mm (4.11 ± 0.11 mm) shell width 1.91-2.35 mm (2.21 ± 0.07 mm). Aperture height 0.93-1.19 mm (1.08 ± 0.06 mm). Aperture width 1.07-1.47 mm (1.39 ± 0.07 mm). Shell width/shell height ratio = 0.54 ± 0.02. Aperture width/aperture height ratio = 1.29 ± 0.05.
Shell minute dextral, elongated narrow, turreted with 7 ¾ round whorls that increase regularly in size and diameter until the last whorl; protoconch orange, smooth, consisting of 1 ¼ whorls, covered with minute pits; teleoconch light orange, consists of about 5 ¾ whorls that increase regularly in size and diameter until the last whorl; spires shouldered; sculpture consists of rather even and rather widely-spaced radial ribs with about 8 ribs/mm on the penultimate whorl and about 6 ribs/mm on the body whorl, the discernible spiral striae between the ribspresent; sutures deep; umbilicus closed; aperture round; peristome is thickened and expanded and doubled; columellar lamella rather bluntly rounded (Fig. 4 View Figure 4 ).
Diagnosis
Shell minute, dextral, turreted, translucent, whitish; protoconch smooth; teleoconch sculpture of widely-spaced radial ribs with discernible spiral striae between the ribs, Aperture rounded, columellar lamella well developed, peristome doubled, thickened and expanded.
Etymology
We named this new species " burapha ," which means “eastern.” This refers to the type locality, which is located in the east and is also in honour of Burapha University, the workplace of the authors.
Distribution
This species is known only from the type locality.
Taxon discussion
The size of the shell, shape of the shell and protoconch of D. burapha sp. n. are similar to D. doichiangdao Panha & Burch, 1998 from Doi Chiang Dao, northern Thailand and Laotian species, D. belonis Möllendorff, 1900. The spire of D. burapha sp. n. is relatively broader than that of those two species. The enlarged penultimate whorl and the body whorl of D. burapha sp. n. are relatively similar in diameter, while the last whorls of both D. doichiangdao and D. belonis are smaller in diameter than the enlarged penultimate whorl. This new species columellar is poorly developed, while well developed in D. doichiangdao and D. belonis .
