Material examined. Holotype: XHQ 24012101, shell height 12.0 mm. Zhongshu Town , Luliang County, Qujing City, Yunnan Province, China, 25.02°N, 103.66°E, June 2022, collected by Yue-Ming He and Hong-Quan Xiang ( Fig. 1 ).

Paratypes: 2 specimens, XHQ 24012102-03, shell height 10.0 mm, June 2022, locality and habitat same as holotype.

Diagnosis. Shell small, ovate-conic, white, with five whorls, shell surface with a keels, body whorl big and swollen, aperture ovate, outer lip thickened.

Description. Shell small, but solid, ovate-conic, white, with five spiral whorls, including two protoconch whorls, teleoconch whorl inflated; other whorls with a keels and fine growth lines, body whorl big and swollen. Apex obtuse. Umbilicus narrow, base white. Aperture ovate, more than half of shell in height, inner lip thickened and smooth, outer lip thickened.

Differential diagnosis. Compared with F. kreitneri , F. sinensis and F. undata , Fenouilia gaorange sp. nov. shell surface smooth, without axial ribs. Compared with Fenouilia pluvia sp. nov., Fenouilia gaorange sp. nov. shell bigger and with a keels.

Etymology. The species name "gaorange " originates from the name of Han Gao's pet cat. We suggest the Chinese common name as " fl吉AEḄDz ".

Distribution and ecology. This species is only found in the lake sediments of Lake Lulianghai in Qujing, Yunnan Province.
