Deladenus bonabensis Bonab, Atighi & Pedram, 2023

Morphology and Anatomy:

Although many species of Deladenus are dimorphic with a fungivorous stage and an insectivorous stage, only a fungivorous stage has been found for D. bonabensis

Female:

Mycetophagous (fungivorous), free-living
Body slender, gradually narrowing toward anteriorly.
Six lines are present in lateral fields.
Lip region low, not offset from body contour.
Stylet small, knobbed, shaft longer than conus.
DEGO at base of the stylet knobs.
Hemizonid at level of nerve ring; secretory-excretory pore posterior to hemizonid.
Pharynx with no median bulb, and with junction with intestine is anterior to the nerve ring; dorsal pharyngeal gland is long, overlapping intestine.
Rectum and anus functional.
Monodelphic-prodelphic; ovary outstretched, oocytes in single or double rows, spermatheca oblong-oval, filled with large sperm cells; crustoformeria with more than four cells in each row.
Vagina modernity sclerotized, vulva with elevated lips, no post-uterine sac and no vulval flap.
Tail is conical, uniformly narrowing to the end, with a small mucro at the tip.

Male:

Present as frequently as females/
General morphology and pharynx similar to females.
Monorchis
Spicules are tylenchiod. Gubernaculum is small and thin. A penial tube is present.
Bursa well developed, enveloping the entire tail.
