Classification:

    Type species of the genus:  Pungentella microdenteta Andrassy, 2009

Morphology and Anatomy:

Most (perhaps all) of the species of Pungentella were in the genus Pungentus.  Andrassy (1963) pointed out that the species listed under Pungentus fell into two groups: one group with a long, curved odontostyle with a small aperture and a double guiding ring, the other with a short straight odontostyle with a larger aperture and a simple guiding ring.  In Andrassy (2009), he established the genus Pungentella to accomodate the latter group.

• Small to medium length, 0.6-2.2 mm
• Cuticle smooth
• Lip region offset from body contour, lips fairly angular
• Vestibule with four small, sclerotized, platelets
• Odontostyle straight, approximately as lons as labials diameter with aperture 25-33% of its length
• Guiding ring simple
• Cylindrus wiedening at > 50% of esophagus length
• Tail short, conoid, ventrally curved or bluntly rounded

Female:

• amphidelphic or opisthodelphic
• Vulva transverse, with or without sclerotization.

Male:

• Spicules dorylaimoid
• Supplements begin anterior to spicules.
