Material examined. 2 ex. Duoyi River , Shizong County, Qujing City, Yunnan Province, China; 24.75°N, 104.49°E, November 2023 by Cen- Song Yang leg. GoogleMaps
Holotype. NNUH20241801 , shell height 8.91 mm, width 7.91 mm, height of the body whorl 7.69 mm.
Paratypes. 1 ex. NNUH20241802 , shell height 8.84 mm, width 7.91 mm, height of the body whorl 7.69 mm, locality and habitat same as holotype .
Locus typicus. Duoyi River, Shizong County, Qujing City, Yunnan Province, China; 24.75°N, 104.49°E.
Etymology. The specific name " heimao " derived from the protagonist in the animated series "Black Cat Detective". We suggest the Chinese common name as " Dzĕ华ĸ ".
Description. Shell small, thick, solid, oval shape, yellow, with black thick 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 81%, with very faint transverse lines. Apex eroded. Suture low. Aperture oval shape, lip thin, inner lip slightly thickened and smooth, white-yellow, outer lip yellowish. Umbilicus absent.
Operculum. ( Fig. 2 E View Figure 2 ) Ovate, smaller than aperture, corneous, thin, brown, length 6.29 mm, width 3.91 mm, and the nucleus located at the bottom left about 1/4.
Radula. ( Fig. 3 E 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. Snout broad, squarish, with long cephalic tentacles, tentacles roughly greater than snout in length.
Remarks. Body whorl taking up most of the shell about 81% of H. heimao sp. nov. (vs. more than H.ovata ), which is a significant feature that distinguishes other Hua species. Hua heimao sp. nov. is most similar to H. yangi , but can nevertheless be easily separated by the outer marginal teeth with four to five denticles.
Habitat and distribution. This species was collected in the Duoyi River, Shizong County, Qujing City, Yunnan Province, China. The species inhabits rivers with a depth of less than 30 cm, slow water flow, and a substrate made of stones and sand.
