Material examined. 4 ex. The springs around Huaguodaqing , Heizhiguo Township, Wenshan City, Yunnan Province, China; 23.69°N, 105.18°E, August 2023 by Jun- Da Zhao leg. GoogleMaps
Holotype. NNUH20240601 , shell height 10.67 mm, width 6.39 mm, height of the body whorl 7.74 mm.
Paratypes. 3 ex. NNUH20240602–4 , shell height 9.14–10.27 mm, width 6.31–7.07 mm, height of the body whorl 7.39–8.41 mm, locality and habitat same as holotype .
Locus typicus. Heizhiguo Township, Wenshan City, Yunnan Province, China; 23.69°N, 105.18°E.
Etymology. This new species is named after Jun-Da Zhao, the collectors of this species. We suggest the Chinese common name as " fl氏华ĸ ".
Description. Shell small, thick, solid, conical, black brown; apex eroded, left three whorls; surface near smooth, growth lines obvious, without spiral ribs, body whorl swollen, taking up most of the shell about 77%. Suture low. Lip thin, inner lip slightly thickened and smooth, brown, outer lip hazel. Umbilicus absent.
Operculum. ( Fig. 2 K View Figure 2 ) Ovate, smaller than aperture, corneous, thin, brown, length 3.32 mm, width 2.24 mm, and the nucleus located at the bottom left about 2/5.
Radula. ( Fig. 3 K View Figure 3 ) Central teeth with triangle-shaped pointed major cusp, and 4–5 smaller rounded cusps on each side. Lateral teeth with enlarged, pointed major cusp and one smaller cusp on inner side. The outer sider of lateral teeth with four smaller cusps. Inner marginal teeth with four and outer with five to six flattened, rounded denticles.
Anatomy. Snout, foot and tentacles grey, around with a brown pigmented. Snout broad, cylindrical, with long cephalic tentacles, tentacles longer than snout in length.
Remarks. Lateral teeth with enlarged, pointed major cusp and one smaller cusps on inner side of H. jundazhaoi sp. nov., which is a significant feature that distinguishes other Hua species. H . jundazhaoi sp. nov. is most similar to H. funingensis ( Du, Köhler, Chen & Yang, 2019) , but can nevertheless be easily separated by the operculum nucleus located at about 2/5 (vs. located at the bottom left edge in H. funingensis ), and apex eroded, left three whorls. 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 five to six flattened (vs. more than or equal to ten flattened in H. vultuosa , H. kunmingensis , and H. luquanensis ).
Habitat and distribution. This species is collected from the springs around Huaguodaqing in Heizhiguo Township, Wenshan City, Yunnan Province. The species inhabits rivers with a depth of less than 30 cm, slow flowing, and the substrate is stone and sand.
