What is "monodontus"

Monodontus is a genus of parasitic nematodes in the subfamily Bunostominae of family Ancylostomatidae. Most of its species occur in rodents and suids, but Monodontus louisianensis is from the white-tailed deer (Odocoileus virginianus) and Monodontus giraffae from the giraffe (Giraffa camelopardalis). An unspecified Monodontus has been recorded from the marsh rice rat (Oryzomys palustris) in Florida.
