[1] It shows remarkable adaptations to the subterranean life, namely loss of pigmentation, reduction of the eye apparatus, thinning of integuments and heavy spination.

[2] Troglohyphantes vignai was described by Brignoli from specimens collected by Augusto Vigna Taglianti (to whom the species was dedicated) in the cave Buco di Valenza.

In the same publication, Pier Marcello Brignoli also described a second Troglohyphantes species (T. rupicapra [2]), which is distinguished from T. vignai by small morphological features.

Such synonymy was recently confirmed on genetic base,[4] and its currently accepted in the World Spider Catalog.

[6] The species show a preference for prey-rich areas of the cave, where the climatic stability is higher.
