Sinoennea woodthorpei — Richardson, 1988: 163.

Type locality. “ Fort Stedman , Burma ” .

Material examined. 1 holotype ( Fig. 19A–D ) + 5 paratypes ( NHMUK 1903.7 .1.3066 [inventory number for both the holotype and the paratypes]), Fort Stedman, Burma (S. Shan Country ), leg. Woodthorpe, coll. Godwin-Austen. 1 shell (Coll. HA), Myanmar, Shan State, Hsihseng centre E ca. 4.5 km, left side of rd. + 1.7 km on unpaved rd., limestone rocks, 20°9.359′N, 97°17.883′E, 1,140 m a.s.l. (locality codes: 2018/39 and 20181007A), coll. K. Okubo, J.U. Otani & A. Hunyadi, 07 October 2018 .

Remarks. Aperture subovoid-quadrangular, parietal callus reaches ca. half of penultimate whorl, rounded. Basal swelling situated in normal distance from peristome, the depression of the palatal wall between the swelling and the peristome clearly visible, corresponding with the lower palatal tooth. Parietal lamella well-developed, its outer end rather straight in the type specimens but curved in the newly collected shell. The outer part of the parietal lamella slightly bent towards columella, inner portion bent in the other direction. Upper palatal tooth low, inconspicuous. Lower palatal tooth situated lower and deeper, elongated, clearly visible from straight view to the aperture. Columellar lamella sharp and relatively low, visible from oblique view to the aperture. Based on the aperture shape, the presence of a basal swelling, and the arrangement of the apertural barriers, this species is classified in Sinoennea .

According to the original description “the best preserved shell has been selected as the type”. Thus, the photographed shell is the holotype.
