Willinema is a rare (infrequent) but widely distributed dorylaimid genus, with some uncertainties about its taxonomy. It was originally proposed by Baqri and Jairajpuri (1967) to accommodate one known species, W. parvum (Williams, 1959), transferred from Thornenema
Andrássy, 1959 and regarded as its type species, and a new species, W. indicum. The genus
was classified under Dorylaiminae de Man 1876, and characterised by a morphological pattern
very similar to that observed in Thornenema, with the very significant difference of its short
and rounded (vs long and filiform) caudal region. Nevertheless, Baqri and Jairajpuri (1967,
p. 364) pointed out that Willinema was closely related to Mesodorylaimus and Labronema too.
In 1969, Siddiqi proposed the new family Thornenematidae to include several long-tailed
genera, Thornenema among them, and suggested that Willinema might be identical to
Thorneella Andrássy, 1960, a member of Thorniidae De Coninck, 1965
