Apex obtuse, apical whorls without micro-sculpture, surface rough (Fig. 3). Body whorl slightly swollen, some individuals with a keel. Lip thin, inner lip little thickened and reflexed, outer lip little reflexed. Without tooth on the columella. Umbilicus narrow.</p><p>All individuals examined to date absence of eyes, with complete degeneration of ocular structures. Snout slender, anterior slight enlargement; tentacles slender, translucent. Mantle smooth, translucent, lack pigment.</p><p>Etymology.</p><p>The name of this species is derived from Di Jiang, a creature from ancient Chinese mythology.</p><p>Habitat and distribution.</p><p>(Fig. 4 A – C) To date, this species has only been found in the vicinity of the cave at its type locality. During the rainy season, the rapid water flow from the cave’s outlet flushes a small number of individuals of this species out of the cave, and the water temperature within the cave is nearly 20 ° C. Nevertheless, no individuals of this species were found in streams near the cave. The few individuals washed out by water during the rainy season were all within two meters of the cave entrance. This species inhabits the gravel and crushed stones underwater in caves, with a dwelling depth of less than 1 meter. Only three live adult individuals of this species were collected. Another species belonging to the family Pomatiopsidae W. Stimpson, 1865 was also discovered at the same locality (Fig. 4 D); its body is also highly transparent, yet it possesses normal eyes. However, only a single individual of this species was found, so no further investigation of it is conducted in the present study. In addition, empty shells of some species of the genus Gyraulus Charpentier, 1837 were found at the locality. Since no live individuals were discovered, it remains unclear whether these belong to cavesnail. Living individuals were maintained in aquaria in the laboratory for observational experiments. They were observed to be photophobic, preferring to hide in dark crevices under rocks; they accepted artificially supplied fish food and also fed on diatoms growing on rock surfaces. Based on its habitat preference, lack of pigmentation, and absence of eyes, we consider this species to be a troglobiont.</p><p>Remarks.</p><p>This species bears resemblance only to certain species of the genus Erhaia xiaoboqiani H. Chen, Y.-M. He, H.-Q. Xiang &amp; X.-P. Wu, 2025, yet it can be distinguished from them by the characteristics of absence of eyes, a thin lip, and a slightly reflexed outer lip. In addition, its relatively slender conical shell, absence of a columellar tooth, and slightly thickened and reflexed inner lip can distinguish it from all currently known species of the genus Erhaia .</p></div>	https://treatment.plazi.org/id/DD19C69ABF9E5137B2CEF8869A856162	Public Domain	No known copyright restrictions apply.
