Ichthyofilaroides is a genus of parasitic nematodes, belonging to the family Guyanemidae Petter, 1974.
Species of Ichthyofilaroides are parasitic as adults in fish, in the musculature, surface of visceral organs and body cavity.[1] According to the World Register of Marine Species, the genus currently (2021) includes a single species, Ichthyofilaroides novaecaledoniensis (Moravec et Justine, 2009) Moravec & Justine, 2020.[2] This species was originally described in 2009 as Ichthyofilaria novaecaledoniensis,[3] then transferred to the genus Ichthyofilaroides in 2020 to become the type-species of the genus.
The new genus was differentiated from Ichthyofilaria mainly by the presence of the buccal capsule and the number and arrangement of the cephalic papillae. Moravec & Justine (2020) added that "since the buccal capsule has not yet been described in any species of the Guyanemidae, it may be necessary to create a new family for Ichthyofilaroides in the future. Nevertheless, since the male of its type species remains unknown, we provisionally assign Ichthyofilaroides to the family Guyanemidae, subfamily Travassosneminae."
