Type locality.

"Lod Cave, Pang Ma Pa District, Mae Hong Son Province, 19°29'36"N, 98°17'18"E and 10°34'03"N, 98°16'41"E, 800 meters elevation (CUIZM, Ver 025), Thailand. All specimens were collected inside the cave, almost two kilometres from the entrance."

Material examined.

Holotype CUIZM 2839 (Ver 025) (reimaged for this study); Thailand (Mae Hong Son): Pangmapa District: Lod Cave , ex S. Panha 2008 (CUMZ 2831), SMF 331472/ 1 paratype.

Diagnosis.

A medium-sized to large, conical Angustopila species with relatively dense spiral striation, a strong parietal tooth, and a weaker upper palatal tooth.

Differential diagnosis.

Angustopila bidentata sp. nov. has a strongly oblique aperture, more rounded whorls, and its parietal callus is detached from the penultimate whorl. Angustopila dominikae is smaller, has a globular shell with a narrower, more horizontally oriented aperture. Angustopila majuscula sp. nov. is larger, has a half whorl more and a wider umbilicus.
