A new species of acanthocephala, Arhythmacathus mysturi is described and compared with similar species. The body of the new species is medium sized and spindle-like in shape and its anterior is covered with spines arrayed in 50 longitudinal rows, 15 in each. Its proboscis is large (0.35～0.46 × 0.11～0.14 mm for the male and 0.38～0.49 × 0.12-0.160 mm for the female), armed with 6 longitudinal rows of hooks, 7 in each. Its lemnisci is 0.55～0.79 × 0.046 ～ 0.098 mm in size. Its testes are oval in shape. The size of the anterior testis is 0.16 ～0.20 mm × 0.15～0.19 mm and that of the posterior testis is 0.15～0.18 mm × 0.14～0.17 mm. Its eggs are 0.0207～0.0294 mm× 0.0051 ～ 0.0069 mm.
