Abstract: Paraprososthenia bronyaae Xiang, He, Lu & Chen, sp. nov. https://zoobank.org/ urn:lsid:zoobank.org:act: 753EF7A4-D8B0-49D4-82E9-54E3E8A716CD Fig. 2 A, Fig. 3 A-C Material examined. Holotype: XHQ 24010101, shell height 21.0 mm. Zhongshu Town [中ŀDz], Luliang County [La县], Qujing City [曲⁂市], Yunnan Province, China, 25.02°N, 103.66°E, June 2021, collected by Yue-Ming He and Hong-Quan Xiang (Fig. 1). Paratypes: 2 specimens, XHQ 24010102-03, shell height 20.2-25.0 mm, June 2023, locality and habitat same as holotype. Diagnosis. Shell small, elongate conic, grey, with ten whorls, the whorls with very obvious keels, aperture ovate, inner lip thickened, outer lip reflexed and thickened. Description. Shell small, but solid, elongate conic, grey, with ten whorls, including two protoconch whorls, teleoconch whorl not swollen; third to fifth whorls with very week keels; other whorls with two very obvious keels; body whorls not swollen. Shell surface with axial growth lines. Apex obtuse. Umbilicus narrow and small, base with one keel around umbilical area. Aperture ovate, inner lip thickened and smooth; outer lip thickened and reflexed. Differential diagnosis. Compared with P. costata (Tchang & Tsi, 1949) and P. constricta (Tchang & Tsi, 1949), Paraprososthenia bronyaae sp. nov. shell surface lacks nodules and with two very obvious keels. Compared to Parapyrgula coggini (Annandale & Prashad, 1919), the shell of Paraprososthenia bronyaae sp. nov. is larger, with more whorls, and more pronounced keels. Etymology. The species name " bronyaae " originates from female characters in the games Honkai Impact 3rd and Honkai: Star Rail. We suggest the Chinese common name as " 布洛ĸṅ川ϐ ". Distribution and ecology. This species is only found in the lake sediments of Lake Lulianghai in Luliang, Yunnan Province.
