Tyleptinae

Scalpenchus scabrosus Siddiqi, 1995

The type species of the genus.

Morphology and Anatomy:

Small nematodes, 0.6 to 0.7 mm long
Lip region not offset, rounded.
Cuticle tylencholaimoid with loose inner layer.
Odontostyle asymmetrical with wide lumen and large aperture.
Odontophore simple, not flanged.
Basal expansion of esophagus pyriform, short.
Tail conoid, ventrally arcuate.

Note:: The asymmetric odontostyle with wide lumen and large aperture is not characteristic of the Leptonchidae and the genus was initally placed in the Mydonomidae by Siddiqi (1995). However, Pena-Santiago (2006) pointed out that the tylencholaimoid cuticle and pyriform basal expansion of the esophagus were more typlical of Leptonchidae.

Female:

Monodelphic, prodelphic.

Males:

2-3 ventromedian supplements.

Distribution:

Sclerolaimus scabrosus described from soil in Cameroon.

Feeding:

The odontostyle with wide lumen and large aperture are not typical of other Leptonchidae and cast doubt on assignment of this genus as a fungal feeder.
