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.

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."
