Morphology and Anatomy:

• Differences between described species are quite subtle. Features with diagnostic value include size and shape of amphidial fovea, number of subcephalic setae, presence/absence of denticles, de Man ratio a, number of precloacal supplements and length of spicules and gubernaculum.
• Head capsule conspicuous, characterized by the thickened cuticle and mostly with an external demarcation between labial and cephalic regions
• Cuticle strongly striated, especially anteriorly
• Amphidial fovea not surrounded by cuticle striations
•  Buccal cavity with distinct teeth and denticles.
• Spinneret present
