Morphology and Anatomy:

Cuticle coarsely striated in anterior body region (annuli ~ 0.6â€“0.8 Î¼m width) but narrower at mid-body (annuli ~ 0.5 Î¼m). Head capsule well-developed. Inner and outer labial sensilla setiform papillae. Four cephalic sensilla (4â€“6 Î¼m long) and eight subcephalic setae (4â€“6 Î¼m long) almost at the same level on the head capsule. Amphidial fovea spiral with 2.0â€“2.5 turns. Eight longitudinal rows of short somatic setae (~ 1â€“3 Î¼m long), reduced to six rows at mid body and four rows in the posterior region. Buccal cavity with 12 cheilorhabdia, a strong dorsal tooth and two smaller ventrosublateral teeth. Pharynx muscular with posterior bulb and plasmatic interruptions, internal lining conspicuous and well-sclerotized. Cardia relatively small. Secretory-excretory system not observable. Tail conical, showing sexual dimorphism i.e., markedly bent in males and with two short subterminal setae in the tip, while more regularly conical and without subterminal setae in female

	Females: Female didelphic, ovaries antidromously refl exed, both genital branches to the left of intestine. Vulva a narrow transversal aperture Ref: Armanteros et al., 201`4


Males: Male monorchic, anterior testis to the right of the intestine. Spicules wide, curved, weakly cephalated. Gubernaculum a narrow rod. One or two small post-cloacal supplements in form of pits
