Aporcelaimus Thorne and Swanger, 1936

Diagnosis:   “Aporcelaiminae.  Large nematodes, 3-10mm long.  Body strongly tapering towards the anterior end.  Cuticle thick, marked with criss-cross lines.  Lip region offset by a deep constriction; lips rather amalgamated.  Mouth a dorsoventral slit.  Odontostyle about as long as lip region width; aperture occupying more than half its length.  Amphids  with fine median support.  Pharynx expanding before its middle.  Vulva transverse; vagina generally with sclerotized pieces.  Spicules of two types: either slender dorylaimoid or strongly swollen.  Tail similar in two sexes, short and rounded or conoid-rounded, in some cases subdigitate. The species of Aporcelaimus are widespread in terrestrial habitats but some species have been found in freshwater habitats” Vinciguerra, 2006.
