Amaurobius tristis L. Koch, 1875

Amaurobius tristis L. Koch, 1875b: 31, pl. 3, f. 3 (♀).

Comment. This species is known from Eritrea only. The type deposition is unknown. Lehtinen (1967) supposed that it is a member of the Titanoecidae . Judging from the schematic figure of the epigyne, an abdomen lacking a pattern and its size it could be Pandava laminata (Thorell, 1878) (Titanoecidae), a species known from this region. The epigyne illustrated by L. Koch is rather more similar to that in Nurscia, and particularly to N. albosignata Simon, 1874 and N. albomaculata (Lucas, 1846), but unlike in A. tristis all species of Nurscia have an abdominal pattern formed by a series of white paired spots. Nurscia albomaculata is known from Northern Africa (Bonnet 1959).
