Allodiplogaster sudhausi is a free-living nematode species in the Diplogastridae family. It was described in 2008 as Koerneria sudhausi,[1] before being moved to the genus Allodiplogaster in 2014.[2] A. sudhausi is omnivorous. It predates on other nematodes,[3] but can be cultured on Escherichia coli OP50 bacterium on agar.[1]

Mouth dimorphism
Like many other Diplogastridae, such as Pristionchus pacificus, A. sudhausi displays phenotypic plasticity, with a polyphenism in its adult mouth-form that leads to formation of one of two distinct stomas (mouth openings) of different dimensions.[1][4] The two morphs that differ in stoma dimension are termed stenostomatous (narrow-mouthed) and eurystomatous (wide-mouthed).[1]
Cannibalism
A. sudhausi has displayed cannibalistic traits, with differences in behaviour observed between the stenostomatous and eurystomatous morphs.[1]
Biocontrol
A. sudhausi is a potential biological control agent. It has been shown to feed on juveniles and eggs of the plant-pathogenic root-knot nematode Meloidogyne javanica in vitro, and introducing A. sudhausi to M. javanica-inoculated soil also reduced tomato root galling.[5]
