There are similarities between Tylaphelenchus Kanzaki, Giblin-Davis, Scheffrahn, Center & Davies, 2009 and
Pseudaphelenchus Ruhm, 1956 so Kanzaki et al (2014) established the
Lan & Giblin-Davis, 2014 and both genera are included
in the subfamily
Tylephelenchinae of the Aphalenchoididae..
Pseudaphelenchus is considered to be an intermediate clade
between Aphelenchidae Fuchs, 1937 and Aphelenchoididae Skarbilovich, 1947
because it has a tylenchid-like bursa and aphelench-like esophageal glands
and a phylogenetic position that is basal to the other aphelenchoidids.
General characteristics of Tylaphelenchus:
Species are associated with wood-inhabiting beetles.
