Holotype. NNUH20240701 , shell height 14.66 mm, width 11.31 mm, height of the body whorl 12.02 mm.
Paratypes. 3 ex. NNUH20240702–4 , shell height 15.06–15.65 mm, width 12.61–12.76 mm, height of the body whorl 11.75–12.71 mm, locality and habitat same as holotype .
Locus typicus. Dongfeng Town, Wudang District, Guiyang City, Guizhou Province, China; 26.60°N, 106.81°E.
Etymology. The specific name " jiahaojingi " from the name of the collector. We suggest the Chinese common name as " fi氏华ĸ ".
Description. Shell small, thick, solid, oval shape, yellowish-brown, with brown horizontal stripes; shell comprising five whorls, surface near smooth, growth lines no obvious, without spiral ribs, body whorl swollen, taking up most of the shell about 80%, with very faint transverse lines. Apex eroded. Suture low. Aperture oval shape, lip thin, inner lip slightly thickened and smooth, white, outer lip yellowish-brown. Umbilicus absent.
Operculum. ( Fig. 2 L View Figure 2 ) Ovate, smaller than aperture, corneous, thin, brown, length 6.91 mm, width 4.37 mm, and the nucleus located at the bottom left about 1/4–3/10.
Radula. ( Fig. 3 L View Figure 3 ) Central teeth with triangle-shaped pointed major cusp, and 2–3 smaller cusps on each side. Lateral teeth with enlarged, pointed major cusp on inner side. The outer sider of lateral teeth takes a faint wavy shape, or even none. Inner marginal teeth with three to four and outer with four to five lattened, rounded denticles.
Anatomy. Snout, foot and tentacles grey, around with a brown pigmented. Snout broad, squarish, with long cephalic tentacles, tentacles roughly greater than snout in length.
Remarks. Lateral teeth have no smaller cusps on inner side of H. jiahaojingi sp. nov., which is a significant feature that distinguishes other Hua species. Hua jiahaojingi sp. nov. is most similar to H. pallens , H. yangi (Du, Yang & Chen, 2023) and H. rotundata , but can nevertheless be easily separated by the operculum nucleus located at about 1/4–3/10 (vs. located at the bottom left edge in H. pallens , H. yangi and H. rotundata ), and the outer sider of lateral teeth takes a faint wavy shape, or even none. The new species can also be clearly distinguished from other Hua congeners by the following features: shell smooth (vs. shell sculptured in H. aristarchorum and H. aubryana ), outer marginal teeth with four to five flattened (vs. more than or equal to eight flattened in H. qiannanensis , H. vultuosa , H. kunmingensis , and H. luquanensis ).
Habitat and distribution. This species was collected from Toubao River in Wudang District, Guiyang City, Guizhou Province. The species inhabits rivers with a depth of less than 100 cm, the water flow was slow, and the substrate was stones.
