Oplegnathidae (Knifejaws)
Etymology: Oplegnathus: Greek, hoplon = weapon + Greek, gnathos = jaw (Ref. 45335).
Eponymy: Peão Lopes of the Lourenco Marques Museum was described as “…a most able collector and technician”. He collected eight of the records of fishes in or near Delagoa Bay that Smith discussed in his paper, presumably including the knifejaw holotype. (Ref. 128868), visit book page.
