Porrhomma subterraneum Simon, 1884 — Simon (1884): p. 359 (descr. juv.); considered a nomen dubium by Thaler (1968: 384); synonymised with P. rosenhaueri by Thaler (1991: 238).

P. subterraneum —Simon (1926): p. 464, 527, Fig. 796 (descr. ♀).

Porrhomma subterraneum must be definitively considered a nomen dubium, because it was described according to a juvenile specimen. It cannot be exactly distinguished from similar species.
