( NHMUK1903.7.1.2100).   Additional material MYANMAR: 6 shells, E. Burmah, coll. Godwin-Austen ( NHMUK).    Description SHELL. Sinistral, small, with very slightly elevated spire; whorls shouldered, which results in a nearly flat dorsal surface; fresh shells light brown; protoconch consists of 2.5 whorls, finely tuberculated; dorsal side and area inside umbilicus dominated by reticulated sculpture; periphery of body whorl dominated by radial lines; whorls 6–6.75 (n = 3), separated by moderately deep suture; peristome thickened and strongly reflected; parietal callus very strong, elevated, sharp, V-shaped, with the upper part of the V being shorter; apertural fold connected to parietal callus. Two opened shells were examined. Parietal wall with a curved, long, posterior, and a shorter anterior lamella; main and intermediate plicae in contact with anterior lamella; main plica connected to apertural fold; intermediate plica about half as long as main plica; lower plica slightly extends beyond posterior lamella in posterior direction, and reaches peristome. Palatal plicae  Plectopylis-like, with three additional horizontal plicae anterior to the vertical plate, which is formed by the accretion of the fourth and fifth plicae. MEASUREMENTS (in mm). D = 8.8–9.9, H = 3.6–4.8 ( syntypes, n = 2).    Differential diagnosis The carinate shell and the horizontal palatal plicae anterior to the vertical plate make the identification of the species easy. A population of  Chersaecia perrieraeis similar in shape, but it has a single lamella. See also under that species.    Distribution   Chersaecia woodthorpeiis known from the typelocality only. 2611489321 67 68 syntype 2611489339 67 68
