Conchological description. Medium-sized Cyclophorus species, overall shell shape rounded, aperture typically circular. Shell height 23.1 to 26.5 mm (mean = 25.0 mm), shell breadth 28.7 to 31.9 mm (mean = 29.9 mm). Number of whorls 5.25. Early whorls with or without bluish colouration. Shape of body whorl uncompressed or slightly compressed; rounded or well-rounded. Lip reflected and simple. Lip colour yellow. Wing-shaped projection at columellar margin present and not pronounced, absent, or present and pronounced. Peripheral band dark brown or absent. Colour pattern generally variable. Typical elements of pattern above position of peripheral band: spiral lines, spiral bands and zig-zag stripes in different shades of brown. Typical elements of pattern below position of peripheral band: spiral lines, spiral bands and transverse lines in darker shades of brown.

Locality and sampling data. VNM073, VNM074, VNM075: Vietnam, Hoa Binh, Cao Duong commune, bought at market stall (20.72542˚, 105.64899˚), collected nearby according to the merchant; purchased on 26 May 2016; purchased by Tu Van Do, Takahiro Hirano & Takumi Saito.
Diagnosis. Cyclophorus sp. 1 can be differentiated from all herein characterised Cyclophorus species based on DNA sequence data. Diagnostic nucleotide substitutions of the cytochrome c oxidase subunit I (COI) gene: 55:A, 94:A, 97:G, 412:G, 511:G (numbers indicate the position in the studied COI fragment).
Remarks. This species is so far undescribed. As the studied material of Cyclophorus sp. 1 has been bought on a market, the species’ exact distribution remains unknown.
