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).
