With 128 described species and 5 subspecies, the spider genus Troglohyphantes (Araneae, Linyphiidae) is a remarkable example of species diversification in the subterranean environment.

Abstract

With 128 described species and 5 subspecies, the spider genus Troglohyphantes (Araneae, Linyphiidae) is a remarkable example of species diversification in the subterranean environment. In this paper, we conducted a systematic revision of the Troglohyphantes species of the Italian Alps, with a special focus on the Lucifuga complex, including the description of two new species (T. lucifer n. sp. and T. apenninicus n. sp). In addition, we provided new diagnostic drawings of the holotype of T. henroti (Henroti complex) and established three new synonymies within the genus. The molecular analysis of the animal DNA barcode confirms the validity of this method of identification of the Alpine Troglohyphantes and provides additional support for the morphology-based species complexes. Finally, we revised the known distribution range of additional Troglohyphantes species, as well as other poorly known alpine cave-dwelling spiders.
