| Redescription |
Caira, J. N. 1985. An emendation of the generic diagnosis of Phoreiobothrium Linton, 1889 (Tetraphyllidea: Onchobothriidae) with a detailed description of bothridia and hooks. Canadian Journal of Zoology 63: 1199-1206. (88) Download PDF |
| Scientific Name Notes | It appears that the Linton paper was published twice. Once, as a separate article in 1924 and again in 1925 along with the other papers in Volume 64. Thus, 1924 is the correct date for this name. |
