Two new species of Acanthobothrium collected from marine fishes in Xiamen, Fujian, China are reported. The type specimens deposited in Parasitology Research Laboratory, Xiamen University. All measurements are given in millimeter unless otherwise stated. Acanthobothrium polytesticularis sp nov. (Fig. 1 — 4) Host Squalus sp.

Genital pores 36. 1%— 42. 9% of proglottid length from posterior end, irregularly alternating. Testes oval, 208 — 228 in number per segment. Cirrus pouch 0. 370-0. 434 (0. 408 + 0. 022) long by 0. 262-0. 294 (0. 278 ± 0. 012) wide, containing spined eversible cirrus. Ovarian arms equal. Vitellaria finely follicular, extending on each side along outer boundary of testes. Acanthobothrium macrocephalum sp nov.

Scolex 2. 705-3. 950 (3. 271 ±0. 544) long by 3. 150-4. 845 (3. 758±0. 746) wide, composed of 4 triloculate bothridia. Each bothridium with a apical sucker and a pad, armed with a pair of bifid hooks. Bothridia 1. 405-2. 275 (1. 850±0. 301) long by 1. 120- 2.020 (1. 683±0. 272) wide.

Mature proglottid wider than long, 0. 490 — 0. 880 (0. 683±0.150) long by 2.105-2. 800 (2. 454±0. 277) wide. Testes 0. 089-0. 114 (0. 097±0. 007) long by 0. 061 — 0. 097 (0. 081 + 0. 012) wide, 124 — 145 in number. Genital pore 59. 6%±4. 2% of proglottid length from posterior end, irregularly alternating.
