DIAGNOSIS. — The medial part of the paracymbium has a pair of separated teeth of similar length. The lamella characteristica of the male bulb has a short and wide distal denticle. In the epigyne, the visible part of the scape has the shape of an anchor in its posterior end, in the middle separating two lateral semicircular projections. Frequently, the opisthosoma presents black spots in the form of circumflex accents, especially marked in its posterior half.

DISTRIBUTION. — T. tenuis has been cited from a large number of localities in the Maghreb area, especially from Algeria and Morocco (Bosmans 2006). It is a common species in the Iberian fauna and with a wide distribution in Europe (Nentwig et al. 2018).
