• Heterocheilidae

  half-bridge flies

  Heterocheilidae is a family of parasitic nematodes (phylum Nematoda) within the order Rhabditida and infraorder Ascaridomorpha. Members are intestinal parasites primarily infecting fish hosts, including elasmobranchs and teleosts. The family includes genera such as Brevimulticaecum, Ortleppascaris, and Dujardinascaris. Notably, the name 'Heterocheilidae' has also been applied to a family of dipteran insects (true flies), but this usage is taxonomically distinct and not accepted in current nematode classification.
