Morphology and Anatomy:

The genus Corollonema is characterized by:

• Small nematodes; body with numerous transverse annulations;
• Cephalic collar with two amphids and four domed, setigerous submedian cephalic papillae.
• Mouth opening with leaf-crown of eight elements arising from the base of the buccal capsule;
• Buccal capsule composed of two regions, anterior part with thin wall, posterior part reduced, surrounded by a thickened annulus.
• Esophagus short; corpus slightly broader posteriorly; isthmus distinct; bulb globose without sclerotised thickenings of lining. Deirids anterior to bulb.

Male;

• Bursa short, lobes distinct. Ventral rays apposed; externolateral ray divergent from and shorter than other laterals; externodorsal ray arises close to lateral trunk; dorsal ray with four branches.
• Spicules elongate, alate, equal.
• Gubernaculum poorly sclerotized.

Female:

• Tail conical.
• Vulva immediately anterior to anus.
• Ovejector J-shaped.
• Egg thin-shelled, ellipsoidal.
