Troglohyphantes vignai
species of arachnid
Troglohyphantes vignai is a species of cave spider of the family Linyphiidae. It is endemic to Italy.
Morphology
Troglohyphantes vignai is a small sized spider with a body length ranging from 3.05 mm to 3.35 mm. It shows remarkable adaptations to the subterranean life, namely loss of pigmentation, reduction of the eye apparatus, thinning of integuments and heavy spination.
Synonymy
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 ), which is distinguished from T. vignai by small morphological features. In recent years, the species validity of T. rupicapra was questioned by Pesarini, who proposed the synonymy T. rupicapra = T. vignai. Such synonymy was recently confirmed on genetic base, and its currently accepted in the World Spider Catalog.
Distribution
Troglohyphantes vignai is endemic to the Western Italian Alps, distributed from the Cottian to the Maritime Alps. Populations of T. vignai are highly isolated from genetic point of view.
The public source identifies “Troglohyphantes vignai” as species of arachnid. This brief keeps that definition visible, then builds a research path around Troglohyphantes, vignai and species.
Why this record matters
A short description can identify a subject without explaining its stakes. For “Troglohyphantes vignai”, the useful work is to connect “species of arachnid” to the records capable of establishing context and consequence.
The date and method of observation matter as much as the stated conclusion, especially where classification or consensus has changed. The source revision retrieved here is dated Jun 9, 2026. The linked authority identifier is Q2138695. None of the 0 selected statements returned an explicit reference.
Scientific names, classifications and consensus can change while older terminology persists in catalogues and historical literature. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
