Cricodorylaimus Ahmad & Sturhan, 2001

Type species of the genus is Cricodorylaimus africanus Ahmad & Sturhan, 2001

Morphology and Anatomy:

Cricodorylaimus is distinguished by the short obese body with strongly striated subcuticle, cuticularised pieces around the stoma and a monodelphic prodelphic female genital tract.

It differs from all known genera in the family Qudsianematidae in the nature of its subcuticle and in being monodelphic prodelphic. .

Less than 1mm length, moderately obese.
Cuticle finely striated.
Subcuticle distinctly striated; striae with serrate margin and with rows of punctations which are more pronounced in the posterior region of body.
Sr\triations of posterior region of body sometimes appearing as scales.
Lip region distinctly offset, wider than the adjoining body; cuticularized pieces present around stoma.
Amphids large with funnel shaped fovea and slitlike aperture.
Odontostyle typical dorylaimid with aperture about one-third of its length. Guiding ring double.
Odontophore simple, rod-like.
Esophagus enlarging posterior to its middle. Cardia short, conoid.
Tail short, conical with bluntly rounded tip.
