Diphyus is a genus of parasitoid wasps belonging to the family Ichneumonidae.
The genus was first described in 1890 by Joseph Kriechbaumer. (In the contents, the new genus is listed as Diphyes, a genus name which had already been used (1817) in the animal kingdom for a cnidarian genus, but in the text he described the genus Diphyus. He immediately follows this description with a description of Diphyes tricolor, which he references later in 1891 with the name Diphyus tricolor. Thus, the species is Diphyus tricolor.
The genus has an almost cosmopolitan distribution.
