Mouth surrounded by a protruding cuticular peribuccal ring forming four lips.
Cuticle transversely striated
Cervical alae are absent.

Microfilariae are sheathed, found in the blood of the host

Female:

Posteriorly twisted into a loose spiral ending in a rounded spiny knob with a pair of lateral cuticular appendages at the tip

Reported median body size for this species (Length mm; width micrometers; weight micrograms) - Click:

Male:

Economic Importance:

Setaria labiatopapillosa can cause cerebrospinal nematodosis (lumbar paralysis) in sheep and goats, which is irreversible and often fatal (Dzimianski et al., 2020).

Ecosystem Functions and Services:

Management:

Albendazole and other anthelminthics are effective for treatent of infected hosts..

Molecular detection methods are expanding the knowledge base of the importance of many species of mosquitoes as vectors of filerial nematodes (Kemenesi et al., 2015).
