Aorolaimus capsici Jimenez Millan, Arias & Fijo, 1964

Synonyms:

Aorolaimus perscitus (Doucet, 1980) Fortuner, 1987 (considered a junior synonym of A. capsici per Arias et al.,(1994)

Pelatamigratus perscitus Doucet, 1980

Morphology and Anatomy:

Female:

Body ventrally curved, tapering slightly towards anterior end.
Cuticle with two layers, outer disinctly annulated and inner finely striated, annuli almost the same width along th
Lateral field with four incisures occupying 18-21 % of body width at midbody,
Areolations present along the neck region and around scutella.
Lip region conical with truncate or somewhat rounded terminus slightly offset, about twice as wide as high; four to five annules and some longitudinal striations
Cephalic framework well developed.
Stylet about three times as long as head width, conus and shaft almost of the same length.
Median bulb rounded to oval, muscular, with sclerotized valve plates,
Pharyngeal gland varying in length, overlapping the intestine dorsally and laterally.
Scutella, always preanal, variable in position, one posterior to the vulva level and another near the caudal region.
Didelphic amphidelphid, ovaries outstretched. Spermatheca rounded to oval,
Vulva as a transverse slit. Epiptygma double, not projecting out of the body surface.
Tail convexo-conoid to hemispherical, nine or ten annuli on ventral side
