Material examined. Holotype: XHQ 24011501, shell height 8.0 mm. Yanjiang Town , Qilin District, Qujing City, Yunnan Province, China, 25.48°N, 103.87°E, June 2022, collected by Yue-Ming He and Hong-Quan Xiang ( Fig. 1 ).

Paratypes: 2 specimens, XHQ 24011502-03, shell height 8.0- 8.1 mm, June 2022, locality and habitat same as holotype.

Diagnosis. Shell small, elongate conic, white, with eight whorls, body whorl and the second to whorl last big and swollen, aperture ovate, outer lip thickened.

Description. Shell small, but solid, ovate-conic, white, with eight spiral whorls, including two protoconch whorls, teleoconch whorl inflated; third to fifth spiral whorls smooth, sometimes with a keels; other whorls smooth; the second to last whorls swollen, sometime with axial ribs; body whorl big and swollen. Teleoconch whorl with a shoulder that is not obviously ramp-like. Apex obtuse. Umbilicus opened, base white. Aperture ovate, near than half of shell in height, inner lip thickened and smooth, outer lip thickened, lips from different growing periods little outward-folding and overlapping.

Etymology. The species name "longfeichen" originates from a biology enthusiast in Yantai, Shandong. We suggest the Chinese common name as " k氏dzǝDz ".

Distribution and ecology. This species is only found in the lake sediments in Qilin District, Qujing, Yunnan Province.
