Oscheius

Oscheius is a genus of nematode.
"O. tipulae" is a satellite developmental genetic model organism used to study vulva formation.
In phylogenetic studies, based on the analysis of sequences of three nuclear genes, "Oscheius" groups with "Caenorhabditis" species and the "Diploscapter", "Protorhabditis" and "Prodontorhabditis" 'Protorhabditis' group, all included in the 'Eurhabditis' group of Rhabditidae genera.
