However, upon examination of the type specimen, it was found that the type locality indicated on the initial handwritten label was Kiu-h (= Kiu [渠] - hien [县], = Qu County [渠县] of Dazhou City) (Fig. 7). Qu County is located in the mountainous area of northeastern Sichuan, hundreds of kilometers away from Chongqing (Tchong-King), with significant environmental and aquatic animal fauna differences (Guo et al. 2021; Guo 2022). In order to find out the true type locality and distribution, we conducted a survey in Chongqing and Sichuan. Finally, we only found specimens that fit the type specimens around Chengdu (Fig. 6). We cannot determine whether the species became extinct in the Qujiang River Basin or if the type locality was incorrect.</p></div>	https://treatment.plazi.org/id/4D584C3A740A5FBD9D9474EC71FC0343	Public Domain	No known copyright restrictions apply.

The first author identified similar specimens during fish surveys in the Qingyijiang River at Yaan (Fig. 6) from 2017 to 2020 but did not preserve the specimens.

In terms of morphology, Shupaludina gen. nov. is most similar to Bapaludina gen. nov. by the similar shell shape, the outward folding and tightly overlapping inner lip, and the small operculum. It can be distinguished from Bapaludina gen. nov. by the presence of keels on the teleoconch (vs. absence), the larger and thicker operculum (OH / AH = 0.72–0.83 vs. 0.55–0.61), the larger crescent-shaped fortification, and the larger, broader, and blunter central denticle of the lateral and inner marginal teeth. Shupaludina gen. nov. is somewhat similar to Sinotaia by the similar shell size and shape (Fig. 5), but differs by the different early teleoconch (almost smooth or with spiral lines vs. smooth but covered with hairs, although these are lost as specimens mature), the larger aperture (AH / SH&gt; 1 / 2 vs. &lt;1 / 2), the outward folding and tightly overlapping inner lip (vs. thin and simple), and the operculum much smaller than aperture (vs. almost same size as aperture). In terms of molecular phylogeny, Shupaludina gen. nov. is the sister group of Dalipaludina but differs by the smaller shell, the blunt apex (vs. pointed), the larger aperture (AH / SH&gt; 1 / 2 vs. &lt;1 / 2), the outward folding and tightly overlapping inner lip (vs. thin and simple), and the operculum much smaller than aperture (vs. almost same size as aperture). Shupaludina gen. nov. has a special overlapping inner lip and small operculum, which is similar to Bakyietaia Zhang, Yen &amp; von Rintelen, 2025. The two genera can be distinguished by the different apex (blunt vs. pointed), the different early teleoconch (rounded vs. keeled), the different keels on the teleoconch (very weak vs. strong), and the larger aperture (AH / SH&gt; 1 / 2 vs. &lt;1 / 2 in most species). Molecular phylogeny and isolated distributions also supported the difference between them. Shupaludina gen. nov. is distributed in the Changjiang River, while Bakyietaia is distributed in the Pearl River, the Red River, the Hainan insular rivers, and the mainland coastal rivers in southern China (Zhang et al. 2025). Yen (1938) recorded Bakyietaia polyzonata (Frauenfeld, 1862) in Sichuan. However, the specimens presented in the article appear to be more akin to Sinotaia . Bakyietaia polyzonata is endemic to the upper Pearl River in southwestern Guangxi and northern Vietnam (Zhang et al. 2025). Bakyietaia wilhelmi (Yen, 1939) recorded in Chengdu were also artificially introduced (Zhang et al. 2025).</p></div>	https://treatment.plazi.org/id/5190098CCD655FE5A8F13A4CE8F4AB13	Public Domain	No known copyright restrictions apply.
