A total of 1956 fishes of 107 species from 3 regions of the Atlantic ocean were examined for larval cestodes and an identification key for larval cestodes of the order Trypanorhyncha is presented. Two species of pseudophyllid larvae were found in 5 out of 11 fish species (n=330) from the Weddell-Sea (Antarctic). Glandicephalus perfoliatus infested Chionodraco myersi (88 %), Cryodraco antarcticus (100 %), Pagetopsis maculatus (10 %) and Trematomus eulepidotus (12 %), while Diphyllobothrium sp. occurred only in Trematomus scotti (1,5 %). Nine different trypanorhynchid larval cestodes could be isolated from 14 out of 44 examined fish species (n= l120) from the Gulf of Guinea (Nigeria): Nybelinia dakari (Pomadasys peroteti (2,6 %)), Otobothrium cysticum (Arius latiscutatus (3,8); Caranx senegallus (40 %); Cynoponticus ferox (20 %); Psettias sebae (62,9 %); Pseudotolithus brachygnathus (8,6 %); P. elongatus (56 %); P. typus (19,4 %); Sphyraena guachancho (40 %)), Otobothrium dipsacum ( Petrocephalus bane (4,3 % ), Otobothrium sp. (Stroma teus fiatola (100 %)), Poecilancistrium caryophyllum (Pseudotolithus senegalensis (4,8 %)), Pseudogrillotia perelica nov. comb. (Caranx senegallus (81,8 %)), Pterobothrium sp. (Galeoides decadactylus (3,2 %)), Tetrarhynchobothriidae (Epinephelus aeneus (12,5 %)) and one unidentified trypanorhynchid larva from Galeoides decadactylus (3,2 %). Two tetraphyllid and eight trypanorhynchid larval cestodes were found in 12 out of 52 fish species (n=506) from the north-east Brazilian coast: Calli tetrarhynchus qracilis (Caranx crysos (25 %); Harengula clupeola (33,3 %); Oligoplites palometa (14,3 %); Opisthonema oglinum (40 %); Scomberomorus maculatus (28,6 %); Selene vomer (20 %)), Lacistorhvnchus sp. (Haemulon aurolineatum (9,1 %), Pseudupeneus maculatus (83,3 %); Scomberomorus maculatus (14,3 %)), Nybelinia sp. I (Haemulon plumieri (10 %); Pseudupeneus maculatus (20 %); Selene vomer (20 %)), Nybelinia sp. II (Pseudupeneus maculatus (10 %)), Nybelinia sp. III (Pseudupeneus maculatus (10 ...
