Taxonomy As far as I can tell: In 1929, Dollfus lists the known genera of trypanorhychs. Genus no. 3 is Hepatoxylon with H. squali Bosc as type species (p. 317).
Genus no 8 is Dibothriocephalus with D. lepidopi Blainville, 1828 as type species (p. 323) .
Then, on the same page, there is a footnote to say that lepidopi falls as a synonym of trichiuri Holten 1802, apparently because Holten got the name of the host wrong and it was the same host (Lepidopus) as Blainville’s.
In Dollfus, 1930 (actually published in 1931), Dollfus again lists the valid genera of trypanorhynchs, but there is no mention of Hepatoxylon, only Dibothriorhynchus with D. trichiuri (Holten, 1802) as the type species.
In 1942 (p. 86), he explains that in 1929 he thought that Hepatoxylon may have been a synonym of Dibothriocephalus (he may have meant that he thought this in 1930/1931), but that he had changed his mind and considered Dibothriocephalus to be a synonym of Hepatoxylon. And so, he takes the oldest species in the genus, H. trichiurid Holten, 1802 as the type species. QED.
I guess that does mean that the synonymy of H. squali with H. trichiuri is on p. 86 of Dollfus (1942), but you really have to read all three papers to sort this out.
