Morphology and Anatomy:

• Adult worms are long and slender, up to 12 cm in length.
• 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: Posteriorly attenuated and spiraled. No caudal alae but a pair of lateral cuticular appendages near the tail tip. Spicules unequal, dissimilar, and winged. Ref: Dzimianski et al, 2020

Distribution:

Worldwide

Economic Importance:

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

Feeding:

Inhabit the peritoneal cavity surface and are free in the lumen of the pleural cavities of ruminants, equids, and swine.

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).
