= Eudorylaimus diadematus (Cobb in Thorne & Swanger, 1936) Andrassy, 1959

= Allodorylaimus diadematus (Cobb in Thorne& Swanger, 1936) Andrassy, 1986

= Dorylaimus cinctus Cobb in Thorne & Swanger, 1936

Morphology and Anatomy:

General: Per Pena-Santiago and Varela-Benavides (2018) The monophyly of Aporcelinus is confirmed on the basis of a definite and recognizable morphological pattern and a highly supported clade obtained by molecular genetic analysis.  However, there is some doubt regarding the classification of Aporcelinus under Aporcelaimidae, as originally proposed, because molecular genetic analysis shows a tentative closer (but not highly supported) relationship with Allodorylaimus, a member of the family Qudsianematidae

• Body length 0.8-2.7 mm; slender.
• Cuticle dorylaimid with two layers, the outer layer thin with very fine striations
• Lip region offset from body contour by a constriction; lip rtegion quite variable among species of the genus, lips angular and elevated or rounded and low, separated or amalgamated.
• Amphid fovea usually stirrup-shaped; amphid aperture usually > 50% of lip width.
• Esophagus doerlaimid with basal; expansion 44-56% of total length.
• Esophago-intestinal junction a cardiawith a dorsal lobe; also a dorsal cell mass adjacent to the junction.
• Tail region consistent across species: conical, tapering gradually to a finely-rounded or acute tip; convex and then concave in lateral view

Distribution:

The genus is widely distributed found in soils and freshwater sediments of world-wide except for Australia, New Zealand or Antarctica, with diversity apparently greater in tropical regions (Varela-Benavides and Pena-Santiago, 2018).  Considered well-represented in natural and culivated areas of Vietnam (Nguyen et al., 2017).
