Pseudaphelenchus yukiae Kanzaki, Giblin-Davis, Scheffrahn, Center & Davies, 2009

Morphology and Anatomy:

Isolated from a subterranean termite, Cylindrotermes macrognathus, in La Selva, Costa Rica.
Morphologically, Pseudaphelenchus yukiae is intermediate between the families Aphelenchidae and Aphelenchoididae in that it has a true bursa supported by bursal limb-like genital papillae but lacks a clear esophageal isthmus.
The molecular phylogenetic status is an inferred position basal to the family Aphelenchoididae and is clearly not part of the clade containing the genus Aphelenchus (=Aphelenchidae).
The authors emended the family definition of Aphelenchoididae to include the unique morphological characters of this new genus.
