Morphology and Anatomy:

General Characteristics:

• Small, thin nematodes, body not coiled.
• Body length 3-6 mm
• Cephalic vesicle well developed and longer than wide with delicate annulations.
• Buccal capsule as wide as long (about 3.7 um wide, and 3.3 um long)
•  Synlophe, as in Molineus, with tips of cuticular ridges oriented perpendicular to body wall.

Males:

• Monorchic, testis long
• One median papilla anterior to cloaca
• Spicules short, divided distally into three branches.
•  Bursa type 2-3 with dorsal ray terminating in 2 sets of 3 branches each. Rays 2 to 6 parallel, ray 4 longer than rays 3 and 5;
• In Neomolineus, ray 4 is longer than the other rays of the lateral lobes and very narrow. In contrast, in all species in Molineus, ray 4 is shorter than the other rays of the lateral lobes
• Tail subconical ending in digitate process

Females:

• didelphic/amphidelphic.
• Vulva at around 75% of body length
