Genus Aporcelaimus
Thorne & Swanger, 1936
Definition: Dorylaiminae. Characterized by the form
of the guiding sheath which, at its forward end, splays out in a funnel-shaped
way, the wide end joining the stoma wall as the anterior fixed ring.
This flared part is frequently plicated. The previous interpretation
of this part was that the guiding ring was absent. The ring is almost
always in the single state.
Mostly largish species varying from 1.5 to 10 mm.
Cuticle often marked by fine interwoven straie. Lip region offset
by constriction. Amphids stirrup-shaped; some species appearing to
have a cuticularized median support. Labial papillae in the usual
apical ring of 6 and a more lateral one of 10. Entrance to stoma
dorso-ventrally elongate, more so than in Dorylaimus (sensu lato).
Spear axial, its aperture 1/2 or more of its length. Posterior part
of the oesophagus massive. Female gonads paired, opposed, reflexed;
orientation of vulva not stated for most species. Spicules large,
arcuate, dorylaimoid. Lateral guiding pieces present. Tails
of both sexes blunt, rounded, convex-conoid to hemispherical.
