Aporcelaimoides Heyns, 1965

Refer to the subfamily Sectonematinae for a discussion of the placement of this subfamily in the Aporcelaimidae rather than the Nygolaimidae.

Morphology and Anatomy:

Slender to very slender nematodes (a = 23â€“75), medium to large size, 1.95â€“5.66 mm long.
Cuticle three-layered, especially obvious at caudal region, with the intermediate layer more refringent and thicker than the outer and the inner ones.
Oral aperture a dorso-ventral, nearly hexagonal slit.
Lip region offset by a distinct constriction or a depression.
Mural tooth attached subventrally, short and with aperture often occupying more than one-half its length.
Guiding ring simple and plicate.
Odontophore rod-like.
Esophagus enlarging gradually, with basal expansion occupying around 0.6 of total length.
Tail similar in both sexes, short, rounded conoid, rounded or truncate.

Female:

Female genital system didelphic-amphidelphic; pars refringens vaginae present or absent;
Vulva a transverse slit.

Ref: Alvarez-Ortega et al (2015).

Males:

Spicules dorylaimoid, well developed.
Ventromedian supplements fewr (0â€“4), widely separated.
