vulva, sharply pointed at tip.

Male:

Spicules paired, apparently partially fused, slender with elongated apex and narrow rostrum.
Male tail spike-like, narrowing abruptly just posterior to spicules.

Sheraphelenchus is distinguished from other genera in the Aphelenchodinae by the well-developed stylet without basal knobs or swellings, vulva located at > 80% of body length and tail having a digitiform spike with a finely pointed terminus (Hunt, 1993). The genus is quite rare. Phylogenetic analysis suggests a close realtionship to Bursapehelenchus (Fang et al., 2015).

Distribution:

Nematodes of the genus Sheraphelenchus have been described or isolated from nitidulid beetles and their typical habitats, i.e., rotten fruit and sap flow (Kanzaki, 2021).

Feeding:

Probably fungal feeders with phoretic associattions with insects. Have been found in associated with decaying fruit and sap flow as substrates.
