N2 - Recent examinations of some marine fishes from off the coast of South Australia revealed the presence of two species of Philometra Costa, 1845 (Nematoda: Philometridae): P. inconveniens n. sp. from the ovary (males) and body cavity (subgravid female) of the southern garfish Hyporhamphus melanochir (Valenciennes) (Beloniformes, Hemiramphidae) and Philometra sp. (gravid and subgravid females) from the body cavity of the Australian barracuda Sphyraena novaehollandiae
Günther (Perciformes, Sphyraenidae) (new host and geographical
records). Specimens of species are described and illustrated based on
light and scanning electron microscopical examinations. Philometra inconveniens n. sp. differs from the most similar species P. longa
Moravec, Barton & Shamsi, 2021, a parasite of the body cavity of
the congeneric host off eastern Australia, mainly by a different
structure of the gubernaculum (absence of dorsal barbs and presence of
lateral extensions on its distal portion). This indicates a high degree
of host specificity of these nematodes in co-occuring congeneric hosts.
