Morphology and Anatomy:

Differs from other species of the genus in:

• Unique structure of the anterior, elevated cloacal lip with a large posterior outgrowth covering the cloacal aperture

• The presence of cervical alae

• Two small preanal papillae on the median dome-shaped precloacal elevation.

• See genus and other species descriptions for general characteristics Cucullanus, C. austropacificus, C. dodsworthi)

Female:

• not known

Male:

• Medium-sized nematodes. Body whitish, elongate,

• Narrow lateral alae present, extending from approximately level of base of pseudobuccal capsule to level of posterior oesophagus

• Oral aperture dorsoventrally elongate, surrounded by raised narrow membraneous ala (collarette) supported by row of ca 100 minute basal teeth.

• Four submedian cephalic papillae and pair of lateral amphids present

• Eesophagus muscular, expanded at anterior end to form bulbous pseudobuccal capsule; posterior part of esophagus also expanded,

• Esophagus opens into intestine through large valve

• Ventral precloacal sucker and subventral oblique muscle bands in region between sucker and cloacal aperture

• Anterior lip of cloaca elevated, forming large outgrowth covering cloacal aperture;

• Large median dome-shaped formation containing 2 papillae present just anterior to anterior cloacal lip

• Spicules equal, alate, with pointed distal ends representing 10% of body length;

• Gubernaculum small, rod-like in lateral view, well sclerotised,

• Genital papillae 10 pairs: 4 pairs of subventral preanal papillae, 1 pair of subventral adanal papillae and 5 pairs of postanal papillae, of which 3 pairs subventral and 2 pairs dorsolateral.

•  Phasmids small, lateral, slightly anterior to level of second pair of subventral postanal papillae

• Tail conical, with rather obtuse tip.
