Porrhomma microps inhabited soil layers at depths between 5 and 135 cm. Porrhomma aff. myops was found at depths of 35–95 cm. Specimens of both species were depigmented and had highly reduced eyes. Compared with the epigean P. pygmaeum, P. myops, which inhabits scree and caves, exhibits significantly longer legs. We interpret it as an example of troglomorphism. Compared with the epigean P. pygmaeum, P. aff. myops is found deep in the soil, and exhibits a significantly smaller cephalothorax. We interpret this as edaphomorphism. We consider the edaphomorphic population of P. aff. myops to be a permanent soil inhabiters.
