Host: Haemulopsis corvinaeformis (Steindachner, 1868) ( Haemulidae ).

New record. Brazil, Atlantic Ocean – Rio de Janeiro State • coast of Angra dos Reis, “ Saco Piraraquara de Dentro ”; 23°00’24”S, 44°19’05”W; CHIOC 39729 .

Type-host: Haemulopsis corvinaeformis [ = Pomadasys corvinaeformis (Steindachner, 1868) ]

Type-locality: Guanajibo and Boquilla, Mayaguez, Puerto Rico (Caribbean) and Loíza, Puerto Rico (Atlantic Ocean).

Description (based on six specimens). Body 2,750 –3,550 (3,079; n = 6) long by 480–550 (513; n = 6) wide. Anterior end with a pair of oval buccal suckers, 80–105 (93; n = 12) long by 75–110 (95; n = 12) wide. Pharynx 62–87 (79; n = 5) long by 70–77 (74; n = 5) wide. Oesophagus short. Intestinal caeca bifurcate at level of genital atrium and extend to posterior region of body proper, joining in one and reaching the haptor. Genital atrium 42–55 (47; n=5) long by 47–50 (47; n=5) wide, with eight to nine spines. Haptor composed of four pairs of pedunculated clamps. Each clamp is formed by two plate-like valves and sclerites: central sclerite with bifurcated base and lateral sclerites. Clamps: pair 1, 80–92 (84; n = 12), pair 2, 85–97 (90; n = 11), pair 3, 80–97 (90; n = 12), pair 4, 77–100 (85; n = 11). Testes 12 in number, post ovarian.
